Sierra Leone - US Consular Information Sheet
June 11, 2007
COUNTRY DESCRIPTION: Sierra Leone is a developing country in western Africa still recovering from a ten-year civil war that ended in 2002.
English is the official language, but Kri
, an English-based language, is widely used.
Tourist facilities in the capital, Freetown, are limited; elsewhere, they are rudimentary or nonexistent.
Read the Department of State Background Notes on Sierra Leone for additional information.

ENTRY/EXIT REQUIREMENTS:
A passport and visa are required.
Visitors are strongly encouraged to obtain visas in advance of travel to Sierra Leone.
Visitors to Sierra Leone are required to show International Certificates of Vaccination (yellow card) upon arrival at the airport with a record of vaccination against yellow fever. See our Foreign Entry Requirements brochure for more information on Sierra Leone and other countries.
The Embassy of Sierra Leone is located at 1701 19th Street NW, Washington, DC 20009; telephone (202) 939-9261.
The Embassy also maintains a website at www.embassyofsierraleone.org.
Information may also be obtained from the Sierra Leonean Mission to the United Nations, 245 East 49th St., New York, NY 10017; telephone (212) 688-1656 and from the website of the Sierra Leonean High Commission in London at http://www.slhc-uk.org.uk/.
Overseas, inquiries should be made at the nearest Sierra Leonean embassy or consulate.

See Entry and Exit Requirements for more information pertaining to dual nationality and the prevention of international child abduction.
Please refer to our Customs Information to learn more about customs regulations.

SAFETY AND SECURITY:
Security in Sierra Leone has improved significantly since the end of the civil war in 2002.
The United Nations Peacekeeping Mission in Sierra Leone (UNAMSIL) withdrew in December 2005 and Sierra Leone resumed responsibilities for its own security. The Sierra Leonean police are working to improve their professionalism and capabilities, but fall short of American standards in response time, communications, and specialty skills.

Areas outside Freetown lack most basic services. Embassy employees are free to travel throughout Sierra Leone.
Travelers are urged to exercise caution, however, especially when traveling beyond the capital.
Road conditions are hazardous and serious vehicle accidents are common.
Emergency response to vehicular and other accidents ranges from slow to nonexistent.

There are occasional unauthorized, possibly armed, roadblocks outside Freetown, where travelers might be asked to pay a small amount of money to the personnel manning the roadblock.
Because many Sierra Leoneans do not speak English, especially outside of Freetown, it can be difficult for foreigners to communicate their identity.
Public demonstrations are rare but can turn violent.
U.S. citizens should are advised to avoid large crowds, political rallies, and street demonstrations, and maintain security awareness at all times.

For the latest security information, Americans traveling abroad should regularly monitor the Department's Internet web site where the current Worldwide Caution Public Announcement, Travel Warnings and Public Announcements can be found.

Up-to-date information on safety and security can also be obtained by calling 1-888-407-4747 toll free in the U.S., or for callers outside the U.S. and Canada, a regular toll-line at 1-202-501-4444.
These numbers are available from 8:00 a.m. to 8:00 p.m. Eastern Time, Monday through Friday (except U.S. federal holidays).

The Department of State urges American citizens to take responsibility for their own personal security while traveling overseas.
For general information about appropriate measures travelers can take to protect themselves in an overseas environment, see the Department of State’s pamphlet A Safe Trip Abroad.
CRIME:
Entrenched poverty in Sierra Leone has led to criminality.
There has been an increase in homicide, armed robbery, and residential burglary.
Petty crime and pick pocketing of wallets, cell phones, and passports are very common.
Law enforcement authorities usually respond to crimes slowly, if at all.
Police investigative response are often incomplete and don’t provide support to victims.
Inefficiency is a serious problem at all levels within the government of Sierra Leone.
Americans traveling to or residing in Sierra Leone should maintain a heightened sense of awareness of their surroundings to help avoid becoming the victims of crime.

Business fraud is rampant and the perpetrators often target foreigners, including Americans.
Schemes previously associated with Nigeria are now prevalent throughout West Africa, including Sierra Leone, and pose a danger of grave financial loss.
Typically these scams begin with unsolicited communication (usually e-mails) from strangers who promise quick financial gain, often by transferring large sums of money or valuables out of the country, but then require a series of "advance fees" to be paid, such as fees for legal documents or taxes.
Of course, the final payoff does not exist; the purpose of the scam is simply to collect the advance fees.
A common variation is the scammer’s claim to be a refugee or émigré of a prominent West African family, or a relative of a present or former political leader who needs assistance in transferring large sums of cash.
Still other variations appear to be legitimate business deals that require advance payments on contracts.
Sometimes victims are convinced to provide bank account and credit card information and financial authorization that drains their accounts, incurs large debts against their credit, and takes their life savings.

The best way to avoid becoming a victim of advance-fee fraud is common sense – if a proposition looks too good to be true, it probably is.
You should carefully check and research any unsolicited business proposal before committing any funds, providing any goods or services, or undertaking any travel.
It is virtually impossible to recover money lost through these scams. Please see the Department of State’s brochures on Advance Fee Business Scams and on International Financial Scams for more information.

INFORMATION FOR VICTIMS OF CRIME:
The loss or theft abroad of a U.S. passport should be reported immediately to the local police and the nearest U.S. Embassy or Consulate.
If you are the victim of a crime while overseas, in addition to reporting to local police, please contact the nearest U.S. Embassy or Consulate for assistance.
The Embassy/Consulate staff can, for example, assist you to find appropriate medical care, contact family members or friends and explain how funds could be transferred.
Although the investigation and prosecution of the crime is solely the responsibility of local authorities, consular officers can help you to understand the local criminal justice process and to find an attorney if needed.

See our information on Victims of Crime.

MEDICAL FACILITIES AND HEALTH INFORMATION:
Quality and comprehensive medical services are very limited in Freetown, and are almost nonexistent for all but most minor treatment outside of the capital.
Persons with unstable chronic medical conditions that require on-going medical treatment or medications are discouraged from traveling to Sierra Leone.
Medicines are in short supply and due to inadequate diagnostic equipment, lack of medical resources and limited medical specialty personnel, complex diagnosis and treatment are unavailable.
The quality of medications in Sierra Leone is inconsistent and counterfeit drugs remain a problem.
Local pharmacies are generally unreliable. In the event medications are needed, such as over-the-counter medication, antibiotics, allergy remedies, or malaria prophylaxis, travelers may contact U.S. Embassy Health Unit personnel to receive general information about reliable pharmacies.

Medical facilities in Sierra Leone are scarce and for the most part sub-standard; outside the capital, standards are even lower.
There is no ambulance service in Sierra Leone, trauma care is extremely limited, and local hospitals should only be used in the event of an extreme medical emergency.
Many primary health care workers, especially in rural areas, lack adequate professional training.
Instances of misdiagnosis, improper treatment, and the administration of improper drugs have been reported.
Life-threatening emergencies often require evacuation by air ambulance at the patient's expense.
For a list of hospitals, visit our website at http://freetown.usembassy.gov/ .

Gastrointestinal diseases and malaria pose serious risk to travelers in Sierra Leone.
For additional information on malaria, including protective measures, see the CDC Travelers’ Health web site at http://www.cdc.gov/malaria/.

Information on vaccinations and other health precautions, such as safe food and water precautions and insect bite protection, may be obtained from the Centers for Disease Control and Prevention’s hotline for international travelers at 1-877-FYI-TRIP (1-877-394-8747) or via the CDC’s internet site at http://www.cdc.gov/travel.
For information about outbreaks of infectious diseases abroad consult the World Health Organization’s (WHO) website at http://www.who.int/en.
Further health information for travelers is available at http://www.who.int/ith.

MEDICAL INSURANCE:
The Department of State strongly urges Americans to consult with their medical insurance company prior to traveling abroad to confirm whether their policy applies overseas and whether it will cover emergency expenses such as a medical evacuation.
Please see our information on medical insurance overseas.
TRAFFIC SAFETY AND ROAD CONDITIONS:
While in a foreign country, U.S. citizens may encounter road conditions that differ significantly from those in the United States.
The information below concerning Sierra Leone is provided for general reference only, and may not be totally accurate in a particular location or circumstance.

Most main roads in Freetown are narrow and paved but have potholes; extremely narrow unpaved side streets are generally navigable.
Most roads outside Freetown are unpaved and are generally passable with a 4-wheel drive vehicle.
However, certain stretches of mapped road are often impassable during the rainy season, which usually lasts from May to September.
During the rainy season, add several hours to travel time between Freetown and outlying areas.
There is a major road repair and resurfacing program going on throughout the country that is slowly improving the quality of roads.
Public transport (bus or group taxi) is erratic, unsafe, and not recommended.
U.S. government employees are prohibited from using public transportation except for taxis that operate in conjunction with an approved hotel and that are rented on a daily basis.

Many vehicles on the road in Sierra Leone are unsafe and accidents resulting from the poor condition of these vehicles, including multi-vehicle accidents, are common.
Many drivers on the road in Sierra Leone are inexperienced and often drive without proper license or training.
Serious accidents are common, especially outside of Freetown, where the relative lack of traffic allows for greater speeds.
The chance of being involved in an accident increases greatly when traveling at night, and Embassy officials are not authorized to travel outside of major cities after dark.

Please refer to our Road Safety page for more information.

AVIATION SAFETY OVERSIGHT: As there is no direct commercial air service between the United States and Sierra Leone, the U.S. Federal Aviation Administration (FAA) has not assessed Sierra Leone’s Civil Aviation Authority for compliance with International Civil Aviation Organization (ICAO) aviation safety standards.
For more information, travelers may visit the FAA’s Internet website at http://www.faa.gov/safety/programs_initiatives/oversight/iasa.

Passengers departing Freetown on certain airlines should expect to pay an airport tax of $40.00 (payable in U.S. Dollars).
Several regional airlines service Freetown’s Lungi International Airport; however, it is not uncommon for them to alter scheduled stops, cancel or postpone flights on short notice, and overbook flights.
Travelers may experience unexpected delays even after checking in and must be prepared to handle alternate ticketing and/or increased food and lodging expenses.
European carriers are typically more reliable.
American citizens departing Lungi Airport have reported incidents of attempted extortion by officials claiming that travel documents were not in order.
Luggage can often be lost or pilfered.

Lungi Airport is located across a large body of water from Freetown.
There are helicopter and ferry services in connection with most major flights to transport passengers to the capital; however, the ferry service has frequent delays.
It should be noted that the ferry terminal is located in East Freetown, which has a higher crime rate than other parts of the capital.
Embassy personnel use available helicopter services, which usually cost $50 each way, to transit from Freetown to the airport.


SPECIAL CIRCUMSTANCES:
Sierra Leone is a cash economy; however, an anti-money laundering law passed in July 2005 prohibits importing more than $10,000 in cash except through a financial institution.
Travelers are advised not to use credit cards in Sierra Leone because very few facilities accept them and there is a serious risk that using a card will lead to the number being stolen for use in fraudulent transactions.
There are no ATMs connected to international networks.
Travelers' checks are not usually accepted as payment; however, travelers’ checks can be cashed at some banks including Sierra Leone Commercial Bank, Standard Chartered Bank and Rokel Commercial Bank.
The traveler must, however, have proof of identification and a signed receipt by the institution where the travelers’ checks were purchased.
Currency exchanges should be handled through a bank or established foreign exchange bureau.
Exchanging money with street vendors is dangerous because criminals may "mark" such people for future attack and there is the risk of receiving counterfeit currency.

Sierra Leone's customs authorities enforce strict regulations concerning the export of gems and precious minerals, such as diamonds and gold.
All mineral resources, including gold and diamonds, belong to the State and only the government of Sierra Leone can issue mining and export licenses.
The legal authority for the issuance of licenses is vested in the Ministry of Mines and Mineral Resources.
Failure to comply with relevant legislation can lead to serious criminal penalties.
For further information on mining activities in Sierra Leone, contact the Ministry of Mines and Mineral Resources:
The Director of Mines, Ministry of Mines and Mineral Resources, Fifth Floor, Youyi Building, Brookfields, Freetown, Sierra Leone; tel. (232-22) 240-420 or 240-176; fax (232-22) 240-574.

Corruption is a problem in Sierra Leone.
Travelers requesting service from government officials at any level may be asked for bribes.
You should report corrupt government officials to the Anti-Corruption Commission at one of the following locations:
The Sierra Leone Anti-Corruption Commission, 3 Gloucester Street, Freetown; 14a Lightfoot Boston Street, Freetown; 37 Kissy Town Road, Bo, Southern Province; Independence Square, Rogbaneh Road, Makeni; tel. (232- 22) 229-984 or 227-100 or 221-701; fax (232-22) 221-900; email: acc@sierratel.sl or info@anticorruption.sl;
and websites www.anticorruptionsl.org/anonymous.html and www.anticorruptionsl.org.

You must obtain official permission to photograph government buildings, airports, bridges, or official facilities including the Special Court for Sierra Leone and the American Embassy.
Areas where photography is prohibited may not be clearly marked or defined.
People sometimes do not want to be photographed for religious reasons or may want to be paid for posing.
Photographers should ask permission before taking someone’s picture.

U.S. citizens who are also Sierra Leonean nationals must provide proof of payment of taxes on revenues earned in Sierra Leone before being granted clearance to depart the country.
The Government of Sierra Leone now recognizes dual U.S.-Sierra Leonean citizenship; however; the U.S. Embassy may have difficulty assisting American citizens involved in legal or criminal proceedings if they entered the country on a Sierra Leonean passport.


Please see our Customs Information.

CRIMINAL PENALTIES:
While in a foreign country, a U.S. citizen is subject to that country's laws and regulations, which sometimes differ significantly from those in the United States and may not afford the protections available to the individual under U.S. law.
Sierra Leone’s judiciary is under-funded and overburdened, and offenders often must endure lengthy pre-trial or pre-hearing delays and detention.
Penalties for breaking the law can be more severe than in the United States for similar offenses.
Persons violating Sierra Leone laws, even unknowingly, may be expelled, arrested or imprisoned.
Penalties for possession, use, or trafficking in illegal drugs in Sierra Leone are severe, and convicted offenders can expect long jail sentences and heavy fines.
Engaging in sexual conduct with children or using or disseminating child pornography in a foreign country is a crime, prosecutable in the United States.
Please see our information on Criminal Penalties.

Travelers should carefully check their passport to see the length of time they are permitted to remain in the country and the validity of their visa.
Travelers leaving the country with an expired visa may incur additional charges.
Any Sierra Leonean visa issues can be regulated at the immigration office at Rawdon Street in Freetown.

CHILDREN'S ISSUES:
For information on international adoption of children and international parental child abduction, see the Office of Children’s Issues website.

A significant number of American prospective adoptive parents have found that Sierra Leonean children offered for adoption are not orphans under U.S. immigration law, which has ultimately resulted in denials of U.S. immigrant visas for children they adopt in Sierra Leonean courts.
Please refer to the Sierra Leone adoption flyer for more information.

REGISTRATION / EMBASSY LOCATION:
Americans living or traveling in Sierra Leone are encouraged to register with the nearest U.S. Embassy or Consulate through the State Department’s travel registration website and to obtain updated information on travel and security within Sierra Leone.
Americans without Internet access may register directly with the nearest U.S. Embassy or Consulate.
By registering, American citizens make it easier for the Embassy or Consulate to contact them in case of emergency.

Date: Thu 28 Nov 2019
Source: World Health Organization Disease Outbreak News [edited]

Sierra Leone health officials, supported by WHO, the US Centers for Disease Control and Prevention (CDC), and other partners, are responding to an outbreak of Lassa fever. On 20 Nov 2019, WHO was informed by the Netherlands' International Health Regulations (IHR) National Focal Point of one imported case of Lassa fever from Sierra Leone. The patient was a male doctor, a Dutch national who worked in a rural Masanga hospital in Tonkolili district, Northern province in Sierra Leone.

The probable route of transmission is believed to be through exposures during a surgical procedure he performed on 2 patients in Masanga hospital on 4 Nov 2019. Both patients died following surgical interventions; one died on 4 Nov [2019] and the 2nd on 19 Nov 2019. Both surgical patients are considered probable cases, and the patient who died on 4 Nov [2019] is believed to be the index case for this outbreak, likely the source of infection of the Dutch doctor.

The doctor's symptoms started on 11 Nov [2019], a week after performing the surgery, and included malaise and headache, followed by fever, diarrhoea, vomiting, and cough. While symptomatic, he attended a surgical training event in Freetown, Sierra Leone, on 11-12 Nov [2019]. This event was also attended by several international participants from the Netherlands and United Kingdom in addition to 35 local participants. On 19 Nov [2019], the symptomatic doctor was medically evacuated to the Netherlands after he did not respond to treatment with antimalarials and antibiotics. The evacuation was managed by a dedicated ambulance plane with 4 staff from a German organization. During the journey, the plane stopped in Morocco (Agadir Airport). As the illness was initially thought to be malaria or typhoid fever, personal protective equipment, other than gloves, were not used, and no specific containment procedures were used during the medical evacuation.

Laboratory specimens from the patient tested positive for Lassa fever by polymerase chain reaction (PCR) and sequencing at Erasmus University Medical Centre in Rotterdam on 20 Nov 2019.

The patient died on the night of 23 Nov 2019.

On 22 Nov 2019, WHO was informed of a 2nd laboratory-confirmed case of Lassa fever in another Dutch healthcare worker, who also worked in the Masanga hospital. Samples from this 2nd case were sent to the Erasmus University Medical Centre in Rotterdam and tested positive for Lassa fever by PCR. The 2nd case also participated in one of the surgical procedures performed by the medically evacuated Dutch doctor. The date of onset of symptoms of the 2nd case was 11 Nov [2019]. This case was subsequently medically evacuated in high containment isolation to the Netherlands and is currently under treatment. Isolation precautions have been implemented.

The Masanga hospital in Sierra Leone where the Dutch doctor worked is supported by several non-governmental organizations with international healthcare workers including staff from countries including Denmark, the Netherlands, and the United Kingdom, alongside national healthcare workers.

Contact tracing and monitoring activities have been initiated in these countries as required.

Sierra Leone
An outbreak investigation and response is ongoing under leadership of the Ministry of Health (MoH), supported by CDC and WHO. As of 24 Nov 2019, in addition to the 2 Dutch cases, 2 further cases among national healthcare workers, one confirmed and another suspected, have been reported from Masanga hospital. Both healthcare workers were involved in the management of the 2 surgical patients operated by the Dutch doctor on 4 Nov [2019]. All high-risk contacts in Masanga hospital are being monitored.

The Netherlands
Several high- and low-risk contacts have been identified among personal contacts and healthcare workers. According to Dutch protocols, they will be monitored until 21 days after the last potential exposure. Five high-risk Dutch contacts who were in Sierra Leone have been repatriated through a dedicated flight and are now under monitoring. Dutch low-risk contacts in Sierra Leone have been advised to perform self-monitoring in situ.

Germany
The 4 medical evacuation flight staff (2 pilots and 2 healthcare workers) spent 8 flight hours in a confined space in the ambulance plane without any barrier between the cockpit and cabin. They have been assessed as moderate-risk contacts. According to German recommendations, they are being monitored for 21 days following the last potential exposure on 19 Nov (until 10 Dec 2019).

United Kingdom (UK)
UK authorities have identified 18 UK nationals as contacts of the 1st Dutch case. Of these 18, 8 are high-risk contacts and were exposed in Masanga hospital while working alongside the doctor or may have been exposed to the 2 patients he operated on 4 Nov [2019]. Of these 8 high-risk contacts, 7 returned to the UK and one went to Uganda. In addition, 13 UK nationals attended a surgical training event in Freetown, Sierra Leone, on 11-12 Nov [2019], which was also attended by the 1st Dutch case while already symptomatic. Of these 13 participants, 3 came from Masanga hospital and belong to the above group of 8 high-risk contacts. The remaining 10 participants were possibly exposed during the training and are considered low-risk contacts. Of these 18 contacts identified (8 high-risk and 10 low-risk contacts), 17 have returned to the UK and are under public health follow-up for 21 days; one high-risk contact went to Uganda. There were also several Dutch and 35 local participants who attended this event. UK authorities are in contact with the organizers, and the names of participants from Sierra Leone and the Netherlands have been shared with respective National IHR Focal Points.

Uganda
One contact, a UK national, who may have been exposed in Masanga hospital on 15 Nov [2019] and subsequently travelled to Uganda on 16 Nov [2019], is now being followed up by the Uganda authorities, and the UK authorities are providing support remotely though public health and consular channels.

The National IHR Focal Point of the Netherlands has also informed their counterpart in Morocco about the potential risk of exposure at the Agadir Airport. Morocco National IHR Focal Point confirmed that the investigation is conducted, and control measures have been implemented to ensure there was no transmission in Agadir.

Sierra Leone is endemic for Lassa fever. Previously, sporadic cases have been exported to Europe from endemic countries in Africa, such as Togo, Liberia and Nigeria. In 2018, a total of 23 confirmed Lassa fever cases with 14 deaths (case fatality rate 61%) were reported from 2 districts of Sierra Leone: Bo district (2 cases; 2 deaths) and Kenema district (21 cases; 12 deaths).

From 1 Jan-17 Nov 2019, of the 182 suspected cases, 10 cases with 6 deaths (case fatality ratio 60%) have been confirmed for Lassa virus infection. All confirmed cases during this period were reported from Kenema district, which has been reporting cases of Lassa fever every year.

Public health response
The International Health Regulations Focal Points and Health Authorities in Denmark, Germany, Morocco, the Netherlands, Sierra Leone, Uganda, and the UK have been collaborating to share information about this event, together with the WHO and US CDC. Contact tracing and monitoring activities for 21 days following the last potential exposure have been initiated in Sierra Leone, Germany, the Netherlands, Uganda, and the UK. Investigations are ongoing in Sierra Leone in Masanga hospital and surrounding areas in Tonkolili district with a deployment of a national rapid-response team, supported by US CDC and WHO.

WHO risk assessment
Lassa fever is an acute viral haemorrhagic fever illness that is transmitted to humans via contact with food or household items contaminated with rodent urine or faeces. Human-to-human infections and laboratory transmission can also occur through direct contact with the blood, urine, faeces, or other bodily secretions of a person with Lassa fever. The overall case fatality rate is 1%; it is 15% among patients hospitalized with severe illness.

Sierra Leone is endemic for Lassa fever, and sporadic cases have been exported to Europe from endemic countries in Africa, such as Togo, Liberia and Nigeria in recent years. However, in general, the secondary transmission of Lassa fever through human contacts is rare.

Data from recent imported cases show that secondary transmission of Lassa fever is rare when standard infection-control precautions are observed. Further, epidemiological investigations are ongoing: human-to-human transmission occurs in both community and healthcare settings, where the virus may spread by contaminated medical equipment. Healthcare workers are at risk if caring for Lassa fever patients in the absence of appropriate infection prevention and control measures. Considering the seasonal flare-ups of cases in humid zones between December and March, countries in West Africa that are endemic for Lassa fever are encouraged to strengthen their related surveillance systems.

WHO advice
Prevention of Lassa fever relies on community engagement and promoting hygienic conditions to discourage rodents from entering homes.  There is currently no approved vaccine. Early supportive care with rehydration and symptomatic treatment improves survival. Family members and healthcare workers should always be careful to avoid contact with blood and body fluids while caring for sick persons.

According to WHO guidance for viral haemorrhagic fever, healthcare staff should consistently implement standard precautions when caring for all patients to prevent infections acquired in a healthcare setting and strictly apply contact precautions, including isolation, when caring for suspected or confirmed Lassa fever patients or handling their clinical specimens or body fluids. Standard precautions are meant to reduce the risk of transmission of bloodborne and other pathogens from both recognized and unrecognized sources. Standard precautions are recommended in the care and treatment of all patients regardless of their perceived or confirmed infectious status. They represent the basic fundamental level of infection prevention and control and include hand hygiene, use of personal protective equipment to avoid direct contact with blood and body fluids, prevention of needle stick and injuries from other sharp instruments, and a set of environmental controls. Sterilization and environmental cleaning should also be particularly strengthened and undergo quality control assessments.

In order to avoid any direct contact with blood and body fluids and/or splashes onto facial mucosa (eyes, nose, mouth) when providing direct care for a patient with suspected or confirmed Lassa virus, personal protective equipment should include
1) clean non-sterile gloves,
2) a clean, non-sterile fluid-resistant gown, and
3) protection of facial mucosa against splashes (mask and eye protection, or a face shield).

Given the nonspecific presentation of viral haemorrhagic fevers, isolation of ill travellers and consistent implementation of standard precautions are key to preventing secondary transmission. When consistently applied, these measures can prevent secondary transmission even if travel history information is not obtained, not immediately available, or the diagnosis of a viral haemorrhagic fever is delayed.

WHO continues to advise all countries in the Lassa fever belt due to the need to enhance early detection and treatment of cases to reduce the case fatality rate as well as strengthen cross-border collaboration. WHO advises against any restrictions on travel or trade to or from Sierra Leone based on the current available information.
======================
[The above report provides the details and timelines related to the 2 confirmed cases of the Dutch physicians and the many suspected contacts. The 2 confirmed cases illustrate the difficulty in identifying Lassa fever cases when the infected individuals are early in the course of the disease so that barriers to transmission of the virus can be implemented. The 1st Dutch physician initially was thought to have malaria or typhoid fever, diseases more common in the area than Lassa fever. It will be interesting to learn if any of the contact individuals in the UK, Germany, or Uganda become infected. - ProMED Mod.TY]

The Hague, Nov 24, 2019 (AFP) - A Dutch doctor who contracted Lassa haemorrhagic fever in Sierra Leone after treating patients has died in hospital, while a second doctor is undergoing treatment, the top Dutch health official said Sunday.

The unnamed doctor was flown back to the Netherlands on Tuesday and had been treated at a special isolation ward at a hospital in Leiden near Schiphol airport.   "The patient... which has been treated in strict isolation, has died last night," Dutch Health Minister Bruno Bruins said.   "A second doctor also has Lassa fever and has been repatriated to the Netherlands. Both doctors were infected in Sierra Leone, most likely during medical treatment," the minister said.

The second patient has been admitted to a hospital in the central Dutch city of Utrecht in an isolation unit which was also used to treat a patient who contracted Ebola in 2014.   In a statement, the Sierra Leonean Health Ministry said the deceased Dutch doctor developed Lassa fever symptoms after performing a cesarean section on a pregnant woman at the Masanga Hospital in central Sierra Leone.

The doctor also helped with the evacuation of a second woman who suffered from a septic wound after an abortion.   Both the women died shortly afterwards.    "He developed signs of fever, headache, and general malaise... and was treated for typhoid, malaria and influenza but symptoms persisted."   He was then flown back to the Netherlands where he tested "positive for Lassa fever on the same day."   The second doctor helped in both the cases and tested positive for the disease. 

Dutch minister Bruins said the Netherlands "is in close contact with those involved in Sierra Leone" and that Dutch nurses who had been in contact with the two Sierra Leonean patients are being flown back.   Lassa fever -- named after the place in Nigeria where it was first discovered in 1969 -- is caused by a haemorrhagic virus which belongs to the same family as Marburg and Ebola, according to the Centres for Disease Control (CDC).    It is mainly spread by rodents and is endemic to parts of West Africa including Sierra Leone, Guinea, Liberia and Nigeria.

A Dutch doctor who was evacuated from Sierra Leone after contracting Lassa fever has died in hospital. The medic was flown home on Tuesday [19 Nov 2019] after being infected in the northern town of Masanga, an area not previously known to have been affected.  He reportedly developed symptoms of the viral haemorrhagic illness after operating on a pregnant woman.  A 2nd Dutch doctor who was also evacuated is being treated for the disease.

Described as a cousin of Ebola [a very distant one virologically - ProMED Mod.TY], Lassa fever is endemic in eastern Sierra Leone, but cases have also been reported in northern and southern parts of the country in the last 5 years. It is also endemic in neighbouring Liberia, Guinea and several other West African states.

The doctor died while being treated in "strict isolation" at a hospital in the city of Leiden, Dutch Health Minister Bruno Bruins was quoted by AFP news agency as saying.

The minister confirmed that a 2nd doctor was in an isolation ward in hospital in the central city of Utrecht after being infected with the virus.

The doctors, who have not been named, were linked to a medical charity and had been working at a hospital in Masanga. In a statement, Sierra Leone's Health Ministry said the deceased doctor showed symptoms of Lassa fever after performing a Caesarean section.  "He developed signs of fever, headache, and general malaise ... and was treated for typhoid, malaria, and influenza but symptoms persisted," it said. He was then airlifted to the Netherlands where he was diagnosed with the disease.

The doctor had also helped with the evacuation of a 2nd woman who suffered from a septic wound after an abortion, AFP reports. Both women died shortly afterwards.
======================
[Lassa fever virus is endemic in Sierra Leone, and cases occur there sporadically. It is unfortunate that these physicians became infected while attending to Lassa fever virus-infected patients. Nosocomial transmission of Lassa fever virus in healthcare facilities, especially hospitals, is not unusual.

It is curious that the BBC report says nothing about the other 5 Dutch nationals and the 3 British doctors who were evacuated also who were mentioned in the tweet. - ProMED Mod.TY]

Freetown, Aug 7, 2019 (AFP) - Seven people have died and more than 8,000 have been made homeless after torrential rain in Sierra Leone caused massive floods, officials said.   "We can confirm the death of seven people, with 8,000 people severely affected by the flooding in Freetown and other parts of the country since last Friday," John Vandy, director of the Disaster Management Office in the National Security Office told AFP on Wednesday.   "The majority of the flood victims are from slum communities and swampy areas," Vandy said.   The government is working with development partners to assess the damage and offer relief, with more heavy rain forecast.   The authorities have urged people to leave flood-prone areas in Freetown after reports of a minor mudslide in an area where more than 1,100 people died in a landslip in 2017.

A 5-year-old girl was brought to the emergency room at Evelina London Children's Hospital [UK] with itchy, rather unsightly sores on both legs. She had recently returned from a weeks-long trip to Sierra Leone, and the lesions, which 1st appeared 3 weeks into her stay there, had become larger and ulcerated.

Diagnosis: cutaneous diphtheria, a disease rarely seen in many industrialised countries, including Britain and the United States, where most children are protected by the diphtheria toxoid vaccine, DTaP, and a booster shot of the tetanus-diphtheria-pertussis vaccine, Tdap.

Still, as more and more Americans of all ages travel abroad, often to less developed areas, travellers and doctors in this country need to be alert to unusual and often perplexing skin infections.

Even though cutaneous diphtheria is not a notifiable disease here [the U.S.], from September 2015 to March 2018, 4 cases were reported to the Centers for Disease Control and Prevention [1]. The patients, 2 from Minnesota and 1 each from Washington and New Mexico, had recently returned from Somalia, Ethiopia and the Philippines. The CDC noted in a weekly report in March [2019] [1] that reported cases of this highly contagious infection had recently increased 10-fold, from an average of only 3 a year during the period 1998 to 2011, to 33 a year during 2012 to 2017.

Still, the agency said, these numbers underestimate the true incidence of such infections. Although the 4 new cases were confined to the skin, the lesions can be a source of a life-threatening respiratory infection in people not adequately immunised against diphtheria. Thus, people who might have had close contact with the patients needed to be checked, perhaps treated with antibiotics, and if they lacked immunity to diphtheria, immunised with diphtheria toxoid-containing vaccine.

Before travelling to developing countries, people often check with the CDC or a travel health clinic to determine what immunisations they may need to update and which health precautions -- like drinking only bottled water -- are recommended. But having visited some pretty wild areas in the last 5 decades, I know that many people neglect to consult travel health experts in advance of their trips and are lax about updating needed vaccines.

Upon returning home with a health complaint, they often consult physicians who may have never seen the condition before or even heard of it since medical school, if then.

While emerging diseases like SARS and Ebola rightly garner widespread attention, Dr Jay S. Keystone of the Toronto Medisys Travel Health Clinic has noted that "skin problems are among the most frequent medical problems in returned travellers."

In a large series of traveller-related skin problems analysed by the GeoSentinel Surveillance Network, Dr Keystone reported that among ill travellers who sought medical care, cutaneous larva migrans, insect bites and bacterial infections were the most common disorders, making up 30 per cent of 4742 cases [<https://wwwnc.cdc.gov/travel/yellowbook/2018/post-travel-evaluation/skin-soft-tissue-infections-in-returned-travelers#5024>]. He added that the reported cases did not include those that were easily treated during travel or that cleared up on their own, probably many more.

"Either toxigenic or nontoxigenic strains of _C. diphtheriae_ can cause cutaneous diphtheria. Cutaneous diphtheria due to toxigenic strains is endemic in tropical countries and has been responsible for infections in travelers to these countries, even in those who are vaccinated. In the United States, cutaneous diphtheria has been most often associated with homeless persons [poor sanitation, poverty, and crowded living conditions] and the organisms isolated from recent cases were nontoxigenic (<http://www.cdc.gov/vaccines/pubs/pinkbook/downloads/dip.pdf>). Cutaneous diphtheria is characterized by skin ulcers, which are usually chronic and may become coinfected with other pathogens such as _Staphylococcus aureus_ and _Streptococcus pyogenes_. Cutaneous diphtheria is uncommonly complicated by toxic cardiac or neurologic manifestations.

Humans are the only reservoir of _C. diphtheriae_. Transmission of _C. diphtheriae_ can occur through respiratory droplets, direct contact with cutaneous infections, and articles soiled with discharges from the respiratory tract or skin lesions. Organisms can be shed for up to 4 weeks without antibiotics, but chronic carriers may shed organisms for 6 months or more. Effective antibiotic therapy promptly terminates shedding. The organisms can survive in dust and clothing for up to 6 months (<http://www.cdc.gov/vaccines/pubs/pinkbook/downloads/dip.pdf>). Shedding from cutaneous lesions can cause respiratory and cutaneous infections in contacts.

Cutaneous diphtheria is treated with erythromycin or penicillin for 14 days. The disease is usually not contagious 48 hours after starting antibiotics. Elimination of the organism should be documented by 2 consecutive negative cultures after therapy is completed. Management of contacts of cutaneous diphtheria should include screening for possible respiratory or cutaneous diphtheria and obtaining nasopharyngeal cultures for _C. diphtheriae_. For close contacts, especially household contacts, a diphtheria booster, appropriate for age, is given. Contacts should also receive antibiotics -- benzathine penicillin G or a 7- to 10-day course of oral erythromycin. Identified carriers in the community should also receive antibiotics. However, if the strain is shown to be nontoxigenic, the CDC recommends that investigation of contacts can be discontinued (<http://www.cdc.gov/vaccines/pubs/pinkbook/downloads/dip.pdf>). Since 1980, cutaneous diphtheria is not a nationally reportable disease in the U.S.  (<http://www.cdc.gov/vaccines/pubs/surv-manual/chpt01-dip.html>)." - ProMED Mod.ML]

Sydney, Dec 10, 2019 (AFP) - The death toll from New Zealand's White Island volcano eruption rose to six late Tuesday, after an injured person died in an Auckland hospital, police said.   "Police can confirm a further person has died following the eruption on Whakaari/White Island, bringing the official toll to six," a police statement said.   Eight more people who remain missing are presumed dead after the volcano erupted Monday.

Sydney, Dec 10, 2019 (AFP) - Toxic haze blanketed Sydney Tuesday triggering a chorus of smoke alarms to ring across the city and forcing school children inside, as "severe" weather conditions fuelled deadly bush blazes along Australia's east coast.   Fire engines raced office-to-office in the city centre with sirens blaring, as inland bushfires poured smoke laden with toxic particles into commercial buildings.   Emergency services responded to an "unprecedented" 500 automatic call-outs inside a few hours according to New South Wales Fire and Rescue's Roger Mentha.

A regional fire headquarters miles from the nearest blazes was itself evacuated while throngs of mask-wearing commuters choked their way through thick acrid air and the organisers of a harbour yacht race declared it was unsafe to proceed.   "The smoke from all the fires is just so severe here on the harbour that you just can't see anything, so it's just too dangerous," said spokeswoman Di Pearson of an event that normally foreshadows the famed Sydney-Hobart yacht race. "The vision is just so poor."   Some of the city's commuter ferries were also cancelled "due to thick smoke" and school kids were kept inside at breaktime and sent home early as pollution levels soared far above "hazardous" levels.

For weeks the east of the country has been smothered in smoke as drought and climate-fuelled bushfires have burned. But the scale of the problem on Tuesday shocked even hardened residents.   Bruce Baker -- an 82-year-old who lives in Gosford, north of Sydney -- said he was skipping his daily morning walk because of the smoke.   "This is the worst it's been, for sure," he told AFP. "It dries your throat. Even if you're not asthmatic, you feel it."   Authorities recommended that the vulnerable cease outdoor activity altogether and that everyone stay inside as much as possible, although one couple braved the toxic air to get married on the waterfront in front of Sydney Harbour Bridge shrouded in smog.

A cricket match between New South Wales and Queensland also went ahead, despite a barely visible ball.   Tuesday had been expected to bring strong winds and high temperatures that made for "severe conditions where embers can be blown ahead of the fire into suburbs and threaten properties."   But New South Wales Rural Fire Service said "deteriorating fire conditions have been delayed by a thick blanket of smoke" over the east of the state.   As the day developed there were nearly 100 bushfire incidents in the state of New South Wales alone and dozens more in Queensland.   Total fire bans were put in place across much of the east of the country and in large parts of western Australia.   Temperatures in some inland areas eased past 44 degrees Celsius (111 Fahrenheit).

- The 'big dry' -
To the northwest of Sydney, several fires already burning for weeks have combined to create a "megafire" that has already destroyed 319,000 hectares (788,000 acres) of land, mostly inside national parks.   Prime Minister Scott Morrison  -- who for weeks has not commented on the smoke haze -- defended his government's handling of the fires and said there were no plans to professionalise the countryside's largely volunteer force.    "Our policy is sensible when it comes to addressing and taking action on climate change. Our actions on climate change are getting the results they're intended to get," he said.   Morrison's conservative coalition has been criticised by former fire chiefs for failing to heed warnings about climate change.   The crisis has been propelled by a prolonged drought that has made vegetation tinder dry.

The Bureau of Meteorology has reported that Australia experienced its driest November on record this year.   The "big dry" has left farmers desperate and small towns facing the prospect of running out of water completely.   A swathe of the east of the country has seen "rainfall deficiencies" since early 2017 -- almost three years.   Many dams in New South Wales are empty and almost all are well below capacity.   Firefighters south of Brisbane recently reported 1,000 litres of water were stolen from tanks at their station.   Amid the shortage, Tuesday also saw the toughest water restrictions in a decade being introduced for Sydney -- with curbs on everything from hosepipe use to washing cars.

Sao Paulo, Dec 10, 2019 (AFP) - Gripping the deadly snake behind its jaws, Fabiola de Souza massages its venom glands to squeeze out drops that will save lives around Brazil where thousands of people are bitten every year.   De Souza and her colleagues at the Butantan Institute in Sao Paulo harvest the toxin from hundreds of snakes kept in captivity to produce antivenom.    It is distributed by the health ministry to medical facilities across the country.

Dozens of poisonous snake species, including the jararaca, thrive in Brazil's hot and humid climate.    Nearly 29,000 people were bitten in 2018 and more than 100 died, official figures show.   States with the highest rates of snakebite were in the vast and remote Amazon basin where it can take hours to reach a hospital stocked with antivenom.   Venom is extracted from each snake once a month in a delicate and potentially dangerous process.

Using a hooked stick, de Souza carefully lifts one of the slithering creatures out of its plastic box and maneuvers it into a drum of carbon dioxide.    Within minutes the reptile is asleep.    "It's less stress for the animal," de Souza explains.    The snake is then placed on a stainless steel bench in the room where the temperature hovers around 27 degrees Celsius (80 degrees Fahrenheit).    De Souza has a few minutes to safely extract venom before the snake begins to stir.      "It's important to have fear because when people have fear they are careful," she says.

- Antivenom 'crisis' -
The snakes are fed a diet of rats and mice that are raised at the leafy institute and killed before being served up once a month.   After milking the snake, de Souza records its weight and length before placing it back in its container.    The antivenom is made by injecting small amounts of the poison into horses -- kept by Butantan on a farm -- to trigger an immune response that produces toxin-attacking antibodies.

Blood is later extracted from the hoofed animals and the antibodies harvested to create a serum that will be administered to snakebite victims who might otherwise die.   Butantan project manager Fan Hui Wen, a Brazilian, says the institute currently makes all of the country's antivenom -- around 250,000 10-15 millilitre vials per year.

Brazil also donates small quantities of antivenom to several countries in Latin America.    There are now plans to sell the life-saving serum abroad to help relieve a global shortage, particularly in Africa.    About 5.4 million people are estimated to be bitten by snakes every year, according to the World Health Organization (WHO). 

Between 81,000 and 138,000 die, while many more suffer amputations and other permanent disabilities as a result of the toxin.   To cut the number of deaths and injuries, WHO unveiled a plan earlier this year that includes boosting production of quality antivenoms.   Brazil is part of the strategy. It could begin to export antivenom as early as next year, Wen says.   "There is interest for Butantan to also supply other countries due to the global crisis of antivenom production," she says.

Dec 9, 2019 (AFP) - New Zealand, struck by a deadly volcanic eruption Monday, lies in a zone where Earth's tectonic plates collide, making it a hotspot for earthquakes and volcanic activity.   In one of its worst natural disasters, a huge mass of volcanic debris from the eruption of Mount Ruapehu triggered a mudslide in 1953 that washed away a bridge and caused a passenger train to plunge into a river with the loss of 151 lives.  After Monday's eruption on New Zealand's White Island, here is a recap of some of the deadliest volcanic eruptions around the world in the past 25 years.

- 2018: Indonesia -
In December the Anak Krakatoa volcano, a small island in the Sunda Strait between Java and Sumatra, erupts and a section of its crater collapses, sliding into the ocean and generating a tsunami. More than 420 people are killed and 7,200 wounded.

- 2018: Guatemala -
The June eruption of the Fuego volcano, about 35 kilometres (22 miles) from the capital, unleashes a torrent of mud and ash that wipes the village of San Miguel Los Lotes from the map. More than 200 people are killed.

- 2014: Japan -
The sudden eruption in September of Mount Ontake, in the central Nagano region, kills more than 60 people in Japan's worst volcanic disaster in nearly 90 years. The mountain is packed with hikers at the time. In 1991 an eruption of the southwestern Unzen volcano kills 43.

- 2014: Indonesia -
At least 16 people are killed on the island of Sumatra in February by a spectacular eruption of Mount Sinabung, which had lain dormant for 400 years before roaring back to life five months earlier. In 2016 villages are scorched and farmland devastated after another eruption kills seven.

- 2010: Indonesia -
Indonesia's most active volcano, Mount Merapi on Java island, starts a series of explosions in October, eventually killing more than 320 people. An 1930 eruption of the volcano killed 1,300 people and one in 1994 claimed more than 60 lives.

- 2002: DR Congo -
The eruption in July of Mount Nyiragongo in the eastern Democratic Republic of Congo destroys the centre of Goma town, along with several residential areas, and kills more than 100 people.

- 1997: Montserrat -
The capital of the small British colony, Plymouth, is wiped off the map and 20 are killed or left missing in avalanches of hot rock and ash clouds when its volcano erupts in June.

- 1995: The Philippines -
At least 70 are killed and another 30 missing after the crater of the Parker volcano in the south of the island of Mindanao collapses. Five years earlier the eruption of Mount Pinatubo, 80 kilometres north of the capital Manila, kills more than 800 people.

- Worst ever -
The explosion of Indonesia's Krakatoa volcano in 1883 is considered the worst ever seen. The eruption sent a jet of ash, stones and smoke shooting more than 20 kilometres (12 miles) into the sky, plunging the region into darkness, and sparking a huge tsunami that was felt around the world. The disaster killed more than 36,000 people.

The most famous eruption in history is that of Mount Vesuvius in modern-day Italy in 79 AD, which destroyed the towns of Herculaneum, Stabiae and Pompeii, wiping out an estimated 10 percent of the population of the three cities.

A total of 31 people have been sickened by salmonellosis at 4 health care facilities in south-eastern Pennsylvania. A majority of those cases occurred after individuals ate pre-cut fruit from New Jersey-based Tailor Cut Produce. The Food and Drug Administration (FDA) announced the salmonellosis outbreak in conjunction with the Pennsylvania Department of Health (DOH) on [Fri 6 Dec 2019]. The North Brunswick distributor has recalled its fruit mix with cantaloupe, honeydew, pineapple and grapes as a result.

Tailor Cut Produce reports that its products may be found in restaurants, banquet facilities, hotels, schools and institutional food service establishments in Pennsylvania, New Jersey and New York. "We recommend that any facility who use Tailor Cut Produce pre-cut fruit to immediately stop and throw it away," Pennsylvania Secretary of Health Dr. Rachel Levine said.

Salmonellosis is an infection caused by _Salmonella_ bacteria that generally affects the intestinal tract. People usually become infected by either eating or drinking contaminated food or water, by contact with infected people or animals, or through contact with contaminated environmental sources.

Dozens of researchers in northwestern China's Gansu province have been infected with brucellosis, an animal-borne disease that causes flu-like symptoms and, potentially, lingering problems. In a statement [Fri 6 Dec 2019], the Lanzhou Veterinary Research Institute, an affiliated institute of the Chinese Academy of Agricultural Sciences, said that the 1st few grad students from the institute's foot-and-mouth disease prevention team tested positive for brucellosis antibodies on [28 Nov 2019]. The labs affected have been closed, the institute said, and national and local health authorities have assembled a team to investigate the outbreak.

Li Hui, an official at the health commission in Lanzhou, the provincial capital, told Sixth Tone on [Mon 9 Dec 2019] that the total number of brucellosis cases at the institute had climbed to 96. None have shown clinical symptoms, according to domestic media, and it remains unclear how they were exposed to the bacteria.

Brucellosis -- also known as Malta, Mediterranean, or undulant fever -- is a zoonotic disease that mainly affects animals, including livestock and dogs, which can in turn transmit the bacteria to humans through direct contact. Symptoms include fever, chills, sweating, lethargy, and aches and pains, according to the WHO. In the absence of early diagnosis and treatment, brucellosis can become a chronic condition that is difficult to cure.

In China, brucellosis is a Class B disease, ranking below a more serious category that includes cholera and plague. Human-to-human transmission has only been known to occur between lactating mothers and their babies. According to state broadcaster China National Radio, the brucellosis outbreak at the Gansu veterinary institute has prompted health checks among local students and staff who fear that they may have come into contact with infected animals.

One of the last brucellosis outbreaks in China occurred in 2011, when an agricultural university in the northeastern Heilongjiang province reported 28 cases stemming from infected goats being used in lab research. The school publicly apologized, fired 2 administrators, and offered each of the students' affected monetary compensation.

Scientific labs are subject to different experimental standards depending on their biosafety level, according to a researcher surnamed Yang at the Shanghai Institutes for Biological Sciences, an affiliate of the Chinese Academy of Sciences.

"If the protection levels don't keep pace (with biosafety levels), there will be a risk of infection," Yang, who studies viruses and works in a Biosafety Level 2+ lab, told Sixth Tone. As a result, labs generally require researchers to undergo safety training or even pass an exam to earn a certification, said Yang, who only used her surname because she was not authorized by her employer to speak to media.

The Lanzhou Veterinary Research Institute describes itself as "China's only authorized research center for working with the live virus that causes foot-and-mouth disease," a highly contagious disease affecting livestock. The institute is reportedly also one of the few in China with Biosafety Level 3 labs, which are required for _brucella_ pathogen studies, according to the National Health Commission.

As the local agriculture department tries to ascertain the source of the recent infections, Lanzhou's health commission said [Fri 6 Dec 2019], it is implementing precautionary measures so that brucellosis does not pose a threat to neighbouring communities. [Byline: Yuan Ye]
=================
[An earlier report suggested that 4 persons were clinically ill but this is not confirmed here.  Brucellosis (<http://www.medicinenet.com/brucellosis/article.htm>) is a disease that is thought to have existed since ancient times, as it was 1st described more than 2000 years ago by the Romans and Hippocrates. It was not until 1887 that a British physician, Dr. David Bruce, isolated the organism that causes brucellosis from several deceased patients from the island of Malta. This disease has had several names throughout its history, including Mediterranean fever, Malta fever, Crimean fever, Bang's disease, and undulant fever (because of the relapsing nature of the fever associated with the disease).

The symptoms and signs of brucellosis may develop from days to months after the initial exposure to the organism. While some individuals may develop mild symptoms, others may go on to develop long-term chronic symptoms. The signs and symptoms of brucellosis are extensive, and they can be similar to many other febrile illnesses, so recognition of potential exposure -- from ingestion of unpasteurized milk or cheese, employment as a veterinarian or veterinary student, in a slaughter house or meat processing plant, or working in a microbiology lab -- is vital. In this outbreak, it is not clear what symptoms the students had or whether they were just seropositive. ProMED would like more information about this episode. - ProMED Mod.LL]

In late November [2019], Uganda health authorities notified the World Health Organization of a fatal Rift Valley fever (RVF) case from Obongi district.  The case was a 35-year-old man from South Sudan who was living in the Palorinya Refugee camp in Obongi district, Uganda. The case had travel history to South Sudan between 12 and 19 Nov 2019 to harvest cassava. While in his home country, he developed fever and other symptoms and was treated for malaria; however, his condition got worse.  He later returned to the refugee camp in Uganda and his symptoms progressed and he was hospitalized. Viral hemorrhagic fever was suspected. Samples were collected and sent to the Uganda Virus Research Institute; however, the patient died. A safe and dignified burial was performed on 22 Nov 2019. As of 24 Nov 2019, a total of 19 contacts were recorded during the active case search including 10 healthcare workers.
===================
[The circumstances and specific location under which the man became infected with Rift Valley fever (RVF) virus in South Sudan is not mentioned. It is worth noting that there was an RVF outbreak in the Eastern Lakes region of South Sudan during the 1st 3 months of last year (2018). At the end of that outbreak, the OIE's follow-up report no. 3 reported: "The event cannot be considered resolved, but the situation is sufficiently stable. No more follow-up reports will be sent. Information about this disease will be included in the next 6-monthly reports."

There were more human cases than animal ones in that outbreak, prompting Mod.AS to comment: "Unfortunately, during the recent South Sudan RVF event, as in most -- if not all -- previous RVF events in other African countries, humans served as sentinels. Improved surveillance in animals is desperately needed in Africa, to allow timely measures applied, predominantly preventive vaccination, before the development of a full-blown epizootic involving secondary infection in humans." Intensified surveillance is needed in South Sudan in those localities where the affected man had been prior to his return to Uganda.

It is likely that RVF virus has persisted in this area in transovarially infected eggs of _Aedes_ mosquito vectors. These eggs can remain viable for long periods of time and hatch when flooded during future rain events, with the subsequent emergence of infected females ready to transmit the virus. This risk provides justification for maintaining livestock of the area well vaccinated into the future. This may have accounted for the reappearance of RVF in South Sudan in 2018, after nearly 2 years without additional reported cases in humans or livestock and again with this human case in 2019. - ProMED Mod.TY]

Obongi district, Uganda is located approximately 50 km (30 mi) from the South Sudan border.
HealthMap/ProMED-mail maps:

According to OIE's data, a total of 2 outbreaks of RVF affecting animals have been reported from Sudan during the event. The 1st outbreak started in the Arabaata dam area, Red Sea state, on 25 Sep 2019, affecting goats. The 2nd (and, so far, last) outbreak started 10 Oct 2019 in the River Nile state, affecting sheep and goats. Both outbreaks have been declared as 'resolved' on 14 Nov 2019.

Outbreak summary:
Total outbreaks = 2 (Submitted)
Species / Susceptible / Cases / Deaths / Killed and disposed of / Slaughtered
Goats / 1700 / 37 / 7 / 0 / 0
Sheep / 1550 / 37 / 5 / 0 / 0

According to the recent (5 Dec 2019) OCHA (UN Office for the Coordination of Humanitarian Affairs) update, the (human) RVF situation in Sudan, as of 26 Oct 2019, was the following: "a total of 345 suspected RVF cases -- including 11 related deaths -- reported in the states of Red Sea (128), River Nile (212), Khartoum (1), White Nile (1), Kassala (2), and Gedaref (1). The most affected age group is 15 to 45 years, which accounts for 83% of the total suspected cases. The male to female ratio is 2.6, with a high proportion of the cases being farmers (37.5 per cent). RVF is endemic in Sudan and 3 outbreaks affecting people have been documented in 1973, 1976, and 2008. During the outbreak in 2008, a total of 747 laboratory-confirmed cases were reported, including 230 deaths."

Egypt suffered its 1st RVF outbreak in 1977/78 with serious human disease and death as well as severe losses in livestock; several additional events have been recorded since. A recent historical review paper [1] concluded: "due to the availability and abundance of the potential vectors, the suitability of environmental conditions, continuous importation of livestock's from Sudan, and the close association of susceptible domestic animals with humans, the RVF virus could possibly occur and circulate in Egypt."   (https://tinyurl.com/whz3pz5)

A syphilis outbreak is worsening in Alberta [Canada], and the majority of new cases are in the Edmonton zone. Edmonton saw 1186 of the 1753 infectious syphilis [primary, secondary and early latent syphilis] cases reported in Alberta in 2019, a total of 68 per cent.

Alberta Health Services [AHS] declared an outbreak in July 2019, saying cases had 'increased dramatically' in the province since 2014. The number increased again in July [2019]  [<https://edmonton.ctvnews.ca/alberta-declares-province-wide-syphilis-outbreak-1.4510737>].

AHS sent a new public health alert to doctors on [27 Nov 2019], asking for their help to control the outbreak [<https://www.albertahealthservices.ca/assets/info/hp/phys/if-hp-phys-moh-ez-syphilis-outbreak.pdf>]. "It's very significant," said Dr Ameeta Singh, a clinical professor in infectious diseases. "That's an alarming rise in new syphilis cases in Alberta." She said it's the highest number of cases the province has seen since the 1940s.

According to Dr Singh, the increase in cases being reported is partially due to a greater number of people getting tested. "We know more people are coming in to get tested, but if we look a bit closer at the data we have, we do see there's, in fact, a [bigger] rise in the number of cases than we would expect to see," said Singh.

Another factor could be the rise in methamphetamine use in Edmonton. "I believe this is a major factor. Meth also stimulates risky sexual behaviour and increases the chance people will engage in multiple, usually casual or anonymous partners as well and not use precautions such as condoms to protect themselves during sex," she said.

What's also alarming, Singh said, is the spike in cases of congenital syphilis, where the disease is passed on to newborns. According to AHS, there have been 38 cases of congenital syphilis in 2019, 31 of which were in the Edmonton area. That accounts for more than half of the 61 cases of congenital syphilis reported since 2014.

"Those are not numbers we should be talking about in Canada ever...in a country that has universal access to health care, in a major city in Canada where syphilis testing is offered to all pregnant women who access prenatal care," she said. "What we're seeing with the congenital syphilis cases is many of the women are not accessing prenatal care until they come into the hospital to deliver and then the tests are being done."
===================
[A recent ProMED-mail post (Syphilis - Canada (04): (AB) RFI http://promedmail.org/post/20190718.6574300) reported a rise in "infectious syphilis" cases over a 4-year period: from 2014 to 2018 but made no mentioned of contributing factors. As illicit drug use has been cited as a contributing factor to recent increases in syphilis cases in the Canadian provinces of Ontario and Manitoba, I questioned in this prior ProMED-mail post if use of illicit drugs, in particular, methamphetamine, could similarly be contributing to the rise of syphilis cases in Alberta. The news article above reports that the rise in methamphetamine use in Edmonton, as well as increased testing for syphilis, are thought to be contributing factors in Alberta.

Methamphetamine can be swallowed, snorted, smoked or injected by needle and syringe

When methamphetamine is injected, transmission of syphilis may occur as a consequence of sharing a needle/syringe contaminated with infected blood from somebody who has primary or secondary syphilis (<https://ucsdnews.ucsd.edu/archive/newsrel/health/04-28TransmissionSyphilis.asp>); but syphilis can also be acquired by direct contact with an infected lesion during oral, vaginal, or anal sex when the drug is taken by any route of administration. Methamphetamine use is associated with sexual behaviors that increase the risk for acquiring syphilis and other sexually transmitted diseases, including having multiple sex partners, inconsistent condom use, and exchange of sex for drugs or money (<https://www.cdc.gov/mmwr/volumes/68/wr/mm6806a4.htm>).

The linkage of methamphetamine use and syphilis transmission is reminiscent of the increase in syphilis among heterosexuals during the crack cocaine epidemic of the 1980s and 1990s, when the practice of trading sex with multiple partners for drugs, especially crack cocaine, played a major role in the transmission of syphilis. Under these circumstances, the identities of sex partners are often unknown, which weakens the traditional syphilis-control strategy of partner notification.

Bacteremia due to _Treponema pallidum_, the cause of syphilis, which occurs during primary, secondary, and latent syphilis, can result in transplacental transmission of this organism to the fetus during pregnancy and cause congenital syphilis. An increase in the incidence of syphilis in women in the population is commonly accompanied by increasing rates of congenital syphilis.

Cox’s Bazar, Bangladesh

Over 635,000 Rohingya refugees and Bangladeshi host community will be vaccinated against cholera in a 3-week-long campaign beginning today at the refugee camps in Cox’s Bazar and nearby areas, to protect vulnerable population against the deadly disease amidst increasing number of cases of acute watery diarrhoea (AWD).


The Oral Cholera Vaccination (OCV) campaign will be implemented in the refugee camps from 8-14 December to reach 139,888 Rohingya aged 1 year and less than 5 years. In the host community, the campaign will take place from 8-31 December and aims to reach any person older than 1 year (495,197). In total, 635,085 people are expected to be reached.

Led by the Ministry of Health and Family Welfare, with support of the World Health Organization (WHO), UNICEF and other partners, the campaign aims to reach people who missed some or all previous cholera vaccination opportunities. The campaign, including operational costs, is funded by Gavi, the Vaccine Alliance.

“We want to equip these populations with more protection against diarrheal diseases. Despite the progresses made to ensure access to quality water and sanitation, such diseases remain an issue of concern: approximately 80% of host community living near the camps have not been targeted in previous OCV campaigns and are still vulnerable”, says Dr Bardan Jung Rana, WHO Representative in Bangladesh.

Earlier rounds of cholera vaccination, which have taken place since the beginning of the emergency response in 2017, have helped prevent outbreaks of the disease. To this date, over 1 million people were vaccinated against cholera.

Heavy rain has led to rivers bursting their banks, forcing the closure of shops and restaurants

Streets in the South Island tourist towns of Wanaka and Queenstown were slowly going under water on Friday, after Lake Wanaka and Lake Wakatipu burst their banks earlier in the week, flooding businesses and sewerage systems.

Water and large debris closed the main street of Wanaka, a popular spot with Instagrammers thanks to its famous tree that appears to have grown out of the lake. On Friday businesses were sandbagging as heavy rain continued to fall.

Sewerage systems in the town were also at risk of contaminating the lake, with the Queenstown Lakes District council taking the precautionary measure of shutting down the sewer connection to a handful of premises.

Wanaka residents were told to be on “high alert” with heavy rain predicted all weekend.

The streets of the usually bustling tourist town were largely empty, and the popular cafes and restaurants on the lake shore were closed.
