Chile US Consular Information Sheet
August 20, 2008
COUNTRY DESCRIPTION:
Chile is a rapidly developing country with a large, educated middle class and a robust free-market economy.
Tourist facilities are generally good and are continu
usly improving.
Read the Department of State’s Background Notes on Chile for additional information.
ENTRY/EXIT REQUIREMENTS:
U.S. citizens entering Chile must have a valid passport.
U.S. visitors will be charged a reciprocity fee at the port of entry, and a small receipt for the fee will be stapled in the last page of the passport.
This visa is valid for multiple entries and remains valid until the expiration of the passport.
In addition, visitors will be issued a tourist visa consisting of a single sheet of paper placed in the passport. This visa is valid for a stay of up to 90 days.
An extension of stay for an additional 90 days is possible, but requires payment of an extension fee.
The visa document must be surrendered to immigration authorities upon departure.

Chilean entry and exit control laws require that a minor child under age 18 traveling unaccompanied must have permission from the parents or legal guardians.
The document must be notarized and, if issued in the United States, authenticated by a Chilean consul in the United States.

If the child is traveling in the company of only one parent or guardian, the non-traveling parent or guardian will also be required to grant permission for travel.
In this case, the document will also need to be notarized and authenticated by a Chilean consul.
The permission to travel may also be notarized by a Chilean notary in Chile.

Parents are required to have documentary evidence of their relationship to the child.
An original birth certificate or certified copy of an original birth certificate is required.
This requirement applies to all foreigners as well as Chileans.
This requirement is increasingly being enforced by Chilean immigration officers.
When traveling with a minor child in Chile on a tourist visa, having such documentation on hand will facilitate entry and departure.

Visit the Embassy of Chile web site www.chile-usa.org for the most current visa information and entry/exit requirements.
Visitors should be aware of the severe Chilean restrictions on the importation of fruit, vegetables & agricultural products.

CRIME:
Crime rates are low to moderate throughout Chile and are moderate in Santiago, Valparaiso, and other major cities.
American citizens visiting Chile should be as careful in cities as they would be in any city in the United States.
There have been few violent crimes committed against Americans.
However, American tourists are at a heightened risk for pick-pocketing, purse or camera snatching, and theft from backpacks and rental cars.
Such crimes have been reported in all areas of Chile frequented by tourists.
In Santiago, visitors should be especially alert to the possibility of crime at the Plaza de Armas and the Mercado Central; at major hotels and restaurants in the Las Condes, Vitacura, and Providencia areas, and in the Suecia and Bellavista entertainment districts.
In Valparaiso, visitors should be especially alert in the port and adjoining tourist areas.
Tourists using taxis in Santiago should be alert to possible scams involving currency switching.
Tourists should also be especially alert while using public transportation, such as the Santiago Metro Subway and public buses and while in the vicinity of Metro stations and bus terminals. The emergency number for the police (Carabineros) is 133.

In many countries around the world, counterfeit and pirated goods are widely available.
Transactions involving such products may be illegal under local law.
In addition, bringing them back to the United States may result in forfeitures and/or fines.
More information on this serious problem is available at www.cybercrime.gov/18usc2320.htm.
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.

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 Chile is provided for general reference only, and may not be totally accurate in a particular location or circumstance
Driving in Chile is on the right-hand side of the road.
Traffic laws in Chile differ from traffic laws in the United States in some respects.
Right-hand turns are generally prohibited at red lights unless otherwise posted.
Seat belts are mandatory. Several modern toll highways have recently been opened in and around Santiago, dramatically improving transit into and through the city.
Major roads are generally in good condition throughout the country.
Some secondary roads, however, may be poorly maintained.
At night, occasional heavy fog in rural areas may lead to vehicle accidents with occasional deaths and injuries.
Care should be taken while driving in the mountains because the roads tend to have many tight switchbacks and may not have guardrails.
Chains are often required and should be used on mountain roads during the winter.
Many major highways in Chile are toll roads; drivers should carry a sufficient amount of local currency to cover the tolls.
The new major highways in and around Santiago generally collect tolls through use of an electronic transmitter issued by the concessionaire and placed on the vehicle.
“Day passes” may be purchased separately.
Vehicles rented at Santiago airport generally are equipped with the electronic transmitter and the rental car companies charge a surcharge for its use.
Some major arteries remain under construction in Santiago and drivers should be alert for detours and delays. Information on the major highways in the Metropolitan Region requiring an electronic transmitter is found at www.concesiones.cl.
Throughout Chile, care should be exercised when changing lanes or merging because many drivers do not signal lane changes and rarely yield to merging traffic.
Many Chilean drivers exceed posted speed limits, do not maintain safe distances, and do not observe posted road signs.
Buses are especially aggressive in moving between lanes.
Speeding is common, including in urban areas.
Traffic jams and detours in Santiago and other areas are common.
Taxis are plentiful and relatively inexpensive.
Drivers should drive with car doors locked at all times, especially in the southern parts of the city and near the airport, as there have been reports of thieves entering cars stopped at traffic lights or moving in slow traffic.
In Santiago, certain major arteries switch directions during morning and evening rush hours.
Visitors to Santiago should obtain up-to-date information on these changes from their auto rental company or the Chilean Automobile Association (please see below).
Visitors that wish to use the public bus and subway system in Santiago should visit the following websites for information on purchasing a “BIP” card, a prepaid ticket required for public buses, routes and other helpful information regarding the public transportation systems: www.transantiagoinforma.cl; www.metrosantiago.cl and www.micros.cl.
Driving under the influence of alcohol in Chile is severely punished, and can result in incarceration if the driver is involved in an accident. In accidents involving injuries or death, police may detain both drivers for many hours.
Visitors must have an international driver’s permit in order to drive legally in Chile. The international driver’s license must be obtained in the United States before traveling to Chile.
Although car rental firms may rent to customers with only a U.S. driver’s license, the police fine foreigners for driving without a valid international permit.

Minefields are found in Chile’s northern border with Peru and Bolivia and on the southern border with Argentina in Patagonia.
Minefields are generally marked, but markers may have been shifted, become obscured or been vandalized.
Travelers should pay attention to markers and follow clearly identified roads and trails when traveling in minefield areas.
Border crossings should only be made at authorized locations.
Persons visiting wilderness areas in the border regions mentioned above should check with park or other local officials concerning minefields and other potential hazards.
Chile is a popular destination for outdoors and adventure sports.
Much of the country is mountain, forest, desert, or glacier.
Despite the best efforts of local authorities, assisting persons lost or injured in such areas can be problematic.
American citizens have been killed in recent years in mountain climbing and whitewater rafting accidents, and seriously injured while skiing.
Persons planning to travel in isolated and wilderness areas should first learn about local hazards and weather conditions.

By Paulina ABRAMOVICH

Santiago, Aug 16, 2019 (AFP) - Once deep in powder this time of year, Chile's ski stations are fighting the ravages of climate change and pollution that have brought less and less snow to the central Andes.   Just a few decades ago, the Andes mountain range could be buried under four meters of snow, forcing the closure of access roads and requiring the use of tractors to get around.

But this year, it's snowed only three times in the Chilean Andes, and never more than 30 centimetres.   It's not just Chile affected, but the whole of the Andes where the area of snow cover in the central zone has diminished by five to 10 percent each decade, according to Raul Cordero, an academic at the University of Santiago.   "But it's not just snow cover that's decreasing, the thickness of the snow cover is also reducing," he said.   "So when we talk about a decrease of the cover of five to 10 percent, this probably signifies a much greater reduction in the volume of available snow over the Andes."

Rising temperatures mean the snow line -- above which snow never melts all year round -- keeps creeping upwards.   The snow melt is even more pronounced in the central zone due to pollution from the Chilean capital, one of the most contaminated urban areas in the region.   A recent study led by Cordero found that soot, or black carbon, from Santiago was settling in the Andes and accelerating the snow melt.   As it's black, it absorbs more solar radiation and heats up quicker.   "When this pollution is over the cities it poisons people and when the wind blows, this pollution goes and is deposited on the mountains and contributes to the snow melt," said Cordero.

- Essential snow cannons -
The upshot is that Chile's ski stations have had a difficult season.    But thanks to the snow cannons, the erection of fences and a tailored piste management policy, the resorts have managed to stay open throughout a winter in which there has been almost no snow.   "All the ski centers in the central zone are without natural snow. However, thanks to the fabrication of snow we've been able to keep open pistes that without this fabrication would not have been able to stay open," Fernando Montenegro, the operations director at Andacor, which operates the El Colorado and Parque Farellones ski stations, told AFP.

El Colorado is 50 kilometers from Santiago and sits at 2,800-meters. It pumps out snow whenever the conditions allow it.   Low temperatures and high humidity is what's needed for the snow cannons to chug into gear and churn out snowflakes from water.   This technology has been around since 1994, but it's never before been in use as much as it is now -- and even then the ski station is only operating at 70 percent capacity.   But even if the situation gets worse, the ski stations will manage, according to Montenegro.   "There's no risk. However, we need to manage the snow and manage the water in the mountain range in a good way."   El Colorado has already invested almost $4 million in buying snow cannons and hopes to increase that to $10 million over the coming years.

- 'Variety so important' -
Last weekend, some 7,000 people descended on El Colorado where ski and snowboard national teams come to train -- although, they're not necessarily happy.   "If there's not enough snow, there's not as many hills. We don't get the variety, we don't get steepness, (or) different slopes: it's so important for us to have that variety," Megan Farrell, a member of the Canadian snowboard team, told AFP.   Amateur skiers also noticed the difference from previous years.   "You can see that the snow is harder. It's not very deep, there are a lot of stones and snow made by the cannons, which makes it feel like you're skiing on a different type of snow," said Chilean Rado Milosevic, 24.

Health authorities in Chile today [28 Mar 2019] confirmed the detection in the north of the country of _Aedes aegypti_, the vector of dangerous diseases such as dengue, Zika, chikungunya, and yellow fever [viruses].

The secretariat of the Ministry of Health in the northern Tarapaca region states that on 21 Mar [2019], a specimen of the mosquito was captured in a ovaposition trap for monitoring the presence of these insects in a women's penitentiary in Iquique city.

According to press reports from this region, the presence of larvae of the mosquito was confirmed by the Public Health Institute, although up to now, no locally acquired clinical cases of these _Aedes aegypti_-transmitted diseases have been reported.

The Tarapaca Secretary of Health, Manuel Fernandez, stated that 193 household visits have been made in the area of detection as part of preventive efforts. The official indicated that the mosquito is not able to transmit the indicated diseases without having previously had contact [bitten] with a person infected by any of these viruses. He also called on the public to collaborate with measures against this vector by opening the doors of their houses to the teams that visit to view hygienic conditions and to maximize the recommended measures with that objective.

According to health authorities, Chile, which borders Peru, Bolivia and Argentina [all of which have the mosquito and these viruses], has natural protection with the Andes mountain chain for the length of the country and extensive deserts in the north that make it difficult, but not impossible, for the mosquito to migrate [into the country]. In this respect, he advised that the effects of climate change could be favourable for the arrival of the mosquito and facilitate its reproduction due to the increase of temperature and humidity in some areas.

To date, no cases of dengue or Zika have been reported in the country except for imported ones.
===========================
[Chile has been fortunate in having escaped locally transmitted cases of these viruses due to the absence of _Aedes aegypti_ (except for far distant Easter Island, which has had cases of dengue and Zika virus infections). That situation of geographic and ecological isolation may now be changing with the discovery of a breeding population of this mosquito in the far north of the country. One hopes that this early detection and a timely surveillance effort will permit the mosquito's elimination. Continued surveillance will be critical, since this mosquito is famous for its ability to be moved around by human activity. - ProMED Mod.TY]

Health authorities alerted the population about the consumption of raw fish after detecting 6 confirmed cases and another 14 suspects of contagion with difilobotriasis [_Diphyllobothrium latum_] at Puerto Octay Hospital. Also known as the tapeworm of fish, [_Diphyllobothrium latum_] is the largest parasite that infects humans.

This animal has the appearance of a worm, can reach up to 10 m [approx. 32 ft] and is lodged in the intestines, where it is able to reproduce. According to Las Últimas Noticias, the Health Seremi of Los Lagos, Scarlett Molt, called on the population to "be responsible with their health and avoid the risk of getting sick through the consumption of raw fish." He also warned that "food should be consumed and purchased only in established places, with sanitary certification."

The academic and member of the Chilean Society of Parasitology, Veronica Madrid, stressed that the parasite is common in dishes such as ceviche, sushi and even in "smoking processes that do not reach enough temperature to devitalize the larva." According to the specialist, the only way to be sure of avoiding its presence in fish is to cook it or freeze it to more than 24 deg C below zero [approx. -11 deg F], something that can only be achieved at an industrial level.
=================================
[_Diphyllobothrium latum_ is only seen in fish caught in fresh water, not in salt water fish. A 10 years-old report from Chile indicated that a resurgence of _D. latum_ in Chile could be linked to salmon aquaculture (Cabello FC. Aquaculture and public health. The emergence of diphyllobothriasis in Chile and the world. Rev Med Chil. 2007;135:1064-71, available at: <https://scielo.conicyt.cl/scielo.php?script=sci_arttext&pid=S0034-98872007000800016&lng=en&nrm=iso&tlng=en>).

Another study found that introduced trout in Lake Panguipulli was much more susceptible to _D. latum_ than the native fish (Torres P, Leyán V and Puga S. Prevalence, intensity, and abundance of infection and pathogenesis caused by diphyllobothriosis in vulnerable, native fish and introduced trout in Lake Panguipulli, Chile.

A 140% increase has occurred in 2018 in cases of hepatitis A, in the area that includes the regions of Bio Bio and Nuble, compared to the same date of 2017. In fact, in 2018, 779 cases have been reported, worrying figures for the authorities due to the increase registered since the start of the outbreak of the disease in 2013. According to the health secretary in Bio Bio, Erick Jimenez, the causes could be associated with the consumption of non-potable water, incorrect handwashing, and lack of adequate cooking of seafood.

The communes most affected by hepatitis A are Coronel, where 122 cases were reported, followed by Talcahuano with 94 and Concepción with 78. Despite the figures recorded in the commune of Cuenca del Carbón, epidemiologist Andrea Silva indicated that there will be no focused work in that commune. As of 9 Sep 2018, a total of 11 940 infants in the area had been vaccinated against hepatitis A. [byline: Nicolas Parra]
======================
[The cases are not broken down in regards to age. In children, most cases of HAV infection are subclinical so it is likely that the cases reported were in adults. In the developing world, HAV is not reported much in adults as most children have been infected, and therefore immune to subsequent infection, by the age of 10. That outbreaks are occurring in the area suggests improvement in potable water so less children are infected and therefore still susceptible to HAV as adults. - ProMED Mod.LL]

The Ministry of Health confirmed that from June 2018 to date, 31 people have been infected with cholera in 3 different regions of the country. The microorganism has been present in Chile for some time, but the Undersecretary of Public Health, Paula Daza, told El Mercurio that "this year [2018] what we have had is an outbreak, because we've had a larger number of cases in a short period of time."

According to data from the Regional Ministerial Secretariat (Seremi) of Health of the [Santiago] Metropolitan Region, of the total number of patients, 29 are in this region, with the municipality of La Florida leading the list with 4 infections. Other communes with reported cases are Huechuraba, Las Condes, Vitacura, La Reina, Penalolen, Puente Alto, La Cisterna, Pedro Aguirre Cerda, Santiago, Maipu, Central Station, Renca, Quinta Normal, Conchali, Independencia, Recoleta, and Providencia.

The list is magnified by other cases that occurred in the regions of Valparaiso and Atacama. Of the total number of patients registered so far, 19 are women, and 18 had a history of other underlying diseases.

The symptoms of the infection are similar to a prominent gastroenteritis. The Ministry of Health confirmed that currently no deaths have been recorded as a result of the infections, but 9 people had to be hospitalized.

As to which polluted irrigated waters were the trigger of the outbreak, the Health Seremi of the Metropolitan Region, Rosa Oyarce, assured the same media that "it was ruled out because all the necessary tests were done to the irrigation canals that go directly to the irrigations of the vegetables." Meanwhile, Deputy Secretary Paula Daza indicated that the cause of the outbreak cannot yet be determined. The health authority stressed that it has been ruled out that the bacterium came from abroad, because the ministry's information indicates that none of the patients took previous trips to other countries that could have caused the infection.  [Byline: Felipe Diaz]
===============================
[In the previous post, 14 cases were reported; now that number has more than doubled. Chile had a toxigenic cholera outbreak that originated in neighboring Peru between 1991 and 1994, affecting approximately 150 persons.

It is not stated if this cluster of cases is related to a non-toxigenic O1 or O139 strain or a non-epidemic strain of non-O1, non-O139 _Vibrio cholerae_. As a review, the flagellar (H) antigens of _V. cholerae_ are shared with many water vibrios and therefore are of no use in distinguishing strains causing epidemic cholera. The O (somatic) antigens, however, do distinguish strains of _V. cholerae_ into 139 known serogroups. Almost all of these strains of _V. cholerae_ are non-virulent. Until the emergence of the Bengal (O139) strain (which is "non-O1"), a single serogroup, designated O1, has been responsible for epidemic cholera.

There are 3 distinct O1 serotypes -- Ogawa, Inaba, and Hikojima -- each of which may display the "classical" or El Tor phenotype (or biotype). The biotypes are distinguished by their expression of surface antigens A, B, and C. Ogawa contains antigens A and B; Inaba contains antigens A and C; and Hikojima contains antigens A, B, and C. The latter serotype is relatively rare.

In almost all cases, non-O1, non-O139 _V. cholerae_ isolates do not possess the genes for cholera toxin. Some isolates can cause substantial diarrhea (1-4). The type III secretion system (TTSS) is a mechanism for Gram-negative bacilli to introduce effector proteins into host cell cytoplasm (5). It has been reported that a functional TTSS is required for at least in some non-O1, non-O139 isolates to induce diarrhea in an animal model associated with small-bowel damage and production of proinflammatory cytokines (6). In addition, TTSS contributes to virulence even in the presence of cholera toxin and TCP (6).

Santiago, Aug 16, 2019 (AFP) - Once deep in powder this time of year, Chile's ski stations are fighting the ravages of climate change and pollution that have brought less and less snow to the central Andes.   Just a few decades ago, the Andes mountain range could be buried under four meters of snow, forcing the closure of access roads and requiring the use of tractors to get around.

But this year, it's snowed only three times in the Chilean Andes, and never more than 30 centimetres.   It's not just Chile affected, but the whole of the Andes where the area of snow cover in the central zone has diminished by five to 10 percent each decade, according to Raul Cordero, an academic at the University of Santiago.   "But it's not just snow cover that's decreasing, the thickness of the snow cover is also reducing," he said.   "So when we talk about a decrease of the cover of five to 10 percent, this probably signifies a much greater reduction in the volume of available snow over the Andes."

Rising temperatures mean the snow line -- above which snow never melts all year round -- keeps creeping upwards.   The snow melt is even more pronounced in the central zone due to pollution from the Chilean capital, one of the most contaminated urban areas in the region.   A recent study led by Cordero found that soot, or black carbon, from Santiago was settling in the Andes and accelerating the snow melt.   As it's black, it absorbs more solar radiation and heats up quicker.   "When this pollution is over the cities it poisons people and when the wind blows, this pollution goes and is deposited on the mountains and contributes to the snow melt," said Cordero.

- Essential snow cannons -
The upshot is that Chile's ski stations have had a difficult season.    But thanks to the snow cannons, the erection of fences and a tailored piste management policy, the resorts have managed to stay open throughout a winter in which there has been almost no snow.   "All the ski centers in the central zone are without natural snow. However, thanks to the fabrication of snow we've been able to keep open pistes that without this fabrication would not have been able to stay open," Fernando Montenegro, the operations director at Andacor, which operates the El Colorado and Parque Farellones ski stations, told AFP.

El Colorado is 50 kilometers from Santiago and sits at 2,800-meters. It pumps out snow whenever the conditions allow it.   Low temperatures and high humidity is what's needed for the snow cannons to chug into gear and churn out snowflakes from water.   This technology has been around since 1994, but it's never before been in use as much as it is now -- and even then the ski station is only operating at 70 percent capacity.   But even if the situation gets worse, the ski stations will manage, according to Montenegro.   "There's no risk. However, we need to manage the snow and manage the water in the mountain range in a good way."   El Colorado has already invested almost $4 million in buying snow cannons and hopes to increase that to $10 million over the coming years.

- 'Variety so important' -
Last weekend, some 7,000 people descended on El Colorado where ski and snowboard national teams come to train -- although, they're not necessarily happy.   "If there's not enough snow, there's not as many hills. We don't get the variety, we don't get steepness, (or) different slopes: it's so important for us to have that variety," Megan Farrell, a member of the Canadian snowboard team, told AFP.   Amateur skiers also noticed the difference from previous years.   "You can see that the snow is harder. It's not very deep, there are a lot of stones and snow made by the cannons, which makes it feel like you're skiing on a different type of snow," said Chilean Rado Milosevic, 24.

Tokyo, Aug 15, 2019 (AFP) - A powerful tropical storm lashed Japan on Thursday, bringing strong winds and torrential rain that claimed at least one life, prompted warnings of landslides and flooding, and sparked evacuation advisories and travel chaos at a peak holiday period.   Severe Tropical Storm Krosa -- one notch below a typhoon -- slammed into the southern Hiroshima region, packing wind gusts of up to 126 kilometres (78 miles) per hour.   Dramatic television footage showed violent winds uprooting trees, snapping lampposts and spinning pods on a Ferris wheel.

Meanwhile, high waves smashed into a breakwater, engulfing a 10-metre lighthouse, while swollen rivers broke their banks and swamped nearby roads.  Authorities issued a voluntary evacuation advisory to around 430,000 people in the storm's path, although few appeared to have heeded the warning.

A 82-year-old man was confirmed dead after he fell in the sea in Hiroshima while trying to moor his boat, a local government spokesman said.    Japanese news agency Kyodo reported that a total of 49 people were injured from Wednesday to Thursday.   "We still have intermittent downpours," said Takayoshi Sugimoto, a disaster management official in the southwestern province of Tokushima.   "We will remain vigilant," he told AFP.

The national disaster management agency said a party of 18 people, including children, were stranded during a barbeque in a valley when a river rose rapidly on Wednesday. They were rescued Thursday morning.   Krosa also sparked travel chaos as people battled to return to major cities following the Obon holiday.   More than 800 domestic flights were cancelled to and from cities in western Japan, and bullet train services were either scrapped or sharply reduced.   Ferries connecting the southern Shikoku island and other parts of Japan were also cancelled as high waves lashed the coast.

The storm brought strong winds and downpours to the capital Tokyo.   Several ceremonies commemorating the end of World War II were cancelled in western Japan due to bad weather.    Krosa weakened significantly from earlier in the week as it stalled in the Pacific Ocean but it boasts an unusually large eye, meaning it is likely to dump rain over a wide area.   It was moving north at 35 kilometres (22 miles) per hour and the rain was expected to last for an extended period.   The storm crossed Japan's mainland and hit the Sea of Japan late Thursday.

Tripoli, Aug 15, 2019 (AFP) - Flights at the Libyan capital's sole functioning airport were suspended Thursday after deadly overnight rocket fire, a spokesman for the country's unity government said.   Wednesday night's rocket fire "killed a guard and wounded several security agents tasked with protecting the airport," said Moustafa al-Mejii, spokesman for the Tripoli-based Government of National Accord (GNA).   He blamed the attack on "the militias of (Khalifa) Haftar" whose forces launched an offensive on the Libyan capital in April.   Arrivals and departures at Mitiga airport were suspended as a result, Mejii said.   Located east of Tripoli, Mitiga is a former military airbase that has been used by civilian traffic since Tripoli international airport suffered severe damage during fighting in 2014.

Mitiga is in a zone under the control of forces loyal to the GNA and has often been targeted, leading to repeated suspensions of flights.   United Nations envoy Ghassan Salame, in a report to the UN Security Council last month, urged "authorities in Tripoli to cease using the (Mitiga) airport for military purposes and for the attacking forces to halt immediately their targeting of it."   The GNA protested at what it said were "untruths" in the envoy's report.   Haftar's self-styled Libyan National Army (LNA) has encountered fierce resistance from pro-government forces in the battle for Tripoli.   A stalemate on the ground in the capital's southern outskirts has led to a greater reliance on air strikes by both sides.

The fighting since April has killed 1,093 people and wounded 5,752 others, according to the World Health Organization.   More than 120,000 people have been displaced.   The LNA said Thursday its air force carried out a strike against an airfield in Zuwara, a town west of Tripoli, and destroyed two hangars allegedly used to house Turkish drones.   "The runway and terminals were spared" at the airfield, which is not open to commercial flights, LNA spokesman General Ahmed al-Mesmari wrote on Facebook.   The GNA, however, posted pictures of a huge crater and debris on the tarmac.   Libya has been mired in chaos since a NATO-backed uprising that toppled and killed dictator Moamer Kadhafi in 2011.

Hong Kong, Aug 15, 2019 (AFP) - Hong Kong's government unveiled HK$19.1 billion (US$2.44 billion) worth of economic relief measures and downgraded its growth forecasts on Thursday as the international hub reels from simmering pro-democracy protests and the US-China trade war.   Last week city leader Carrie Lam warned that 10-weeks of anti-government protests were hitting businesses like a "tsunami".    On Thursday, financial chief Paul Chan predicted the city's economy would grow by a miserly zero to one percent this year, the worst rate since 2009 after the global crash hit.

But as he announced a raft of sweeteners in a surprise "mini-budget", he denied the move was linked to the roiling unrest.   "The measures that we have just announced... trying to tackle the current economic difficulties and the coming economic headwinds, is not related to the political difficulties that we are facing," Chan told reporters.   Instead, he said, the primary headwinds remained ongoing trade tensions between Washington and Beijing -- two major markets for Hong Kong -- and the possible impact of Brexit.    "Based on the latest developments and assessments on the outlook, the Hong Kong economy will continue to face an austere environment for the rest of the year," he said.

Nonetheless, the sweeteners seemed to be aimed at winning over support from moderate Hong Kongers as the city reels from the protests.    The measures included financial breaks for small businesses, more generous student subsidies and goodies for low-income households.  Ten weeks of unprecedented rallies, demonstrations and occupations in Hong Kong have seen millions of people take to the streets in the biggest challenge to China's rule of the semi-autonomous city since its 1997 handover from Britain.   The social and political unrest was triggered by a controversial bill which would have allowed extraditions to mainland China, but has evolved into a call for wider democratic reforms and a halt to sliding freedoms.

The retail and tourism sectors have been especially hit by the drop in arriving visitors to the city, but the property market remains strong.   At a "citizens press conference" on Thursday, one protest group blamed the city's economic woes on the local leaders who they accused of undermining the city's business appeal by kowtowing to Beijing.

Johannesburg, Aug 15, 2019 (AFP) - South Africa on Thursday announced visa waivers for four countries in a bid to boost tourism amid an economic crisis and falling visitor numbers.   Visitors from Qatar, Saudi Arabia, United Arab Emirates and New Zealand will no longer require a visa to visit for holiday, conferencing and business purposes, Home Affairs Minister Dr Aaron Motsoaledi said.

The unilateral decision comes as official tourism figures released in May reflected a dip in the overall number of visitors to South Africa from Europe and the Middle East in the first financial quarter of the year, normally one of the most popular times to visit.   Foreign traveller arrivals decreased by more than 10 percent between April and May 2019 alone.   Motsoaledi said the South African government was engaging with Qatar, Saudi Arabia, United Arab Emirates and New Zealand about a similar relaxation of entry requirements for SA citizens.   He argued the move by his department would boost tourism "and by extension growing the economy and creating jobs".

South Africa's economy has hit trouble, with gross domestic product (GDP) contracting by 3.2 percent in the first three months of 2019 and unemployment at a record high of 29 percent.   The government estimates there is potential to create 2.1 million jobs in the tourism sector by 2028.   South Africa is in talks to extend the visa waiver to Ghana, Cuba and Principe and Sao Tome.    The country has already waived the visa requirement for 82 of the 193 countries who are UN members.

In early July [2019], 2 children from Sathyamangalam in Tamil Nadu's Erode district succumbed to diphtheria. Around this time, several other cases of diphtheria were being reported from the state. The latest information shows that at least 50 people have been admitted to the Coimbatore Medical College and Hospital with diphtheria.

Health officials in the state have begun stepping up measures to ensure that the spread of the disease is contained and that more people are vaccinated. The Directorate of Public Health (DPH) even issued an alert to doctors in Chennai to treat all children presenting with sore throat with an antibiotic used to treat the disease, without waiting for the confirmation of a diagnosis.

Despite several campaigns to raise awareness about the importance of vaccination and ensuring that children are vaccinated according to the immunisation schedule, officials note that discrepancies in immunisation have played a large role in the current outbreak of diphtheria.

Tamil Nadu's Deputy Director of Public Health, Dr. K Kolandaswamy, had earlier told TNM that the current spike in the number of cases had to do with lack of immunisation. While several parents had skipped vaccinating their children at a young age, many others had not ensured that the booster dose was taken at a later age. However, in light of the recent outbreak in which both young people and adults have been affected, preventive measures have been stepped up. Not only are children being given the vaccine and booster doses (as deemed necessary), but so are adults.

Diphtheria is a disease caused by the organism _Corynebacterium diphtheriae_ and is highly contagious. Symptoms of diphtheria are often very similar to that of a common cold or any mild respiratory infection, which makes it difficult to differentiate between diphtheria and a more generic infection.

An infected individual may begin to present with symptoms anywhere from 2 to 10 days after exposure to the bacteria. The infected person usually develops a sore throat, which aggravates and will generally develop other respiratory issues as well, if left untreated. While the treatment for diphtheria consists of antibiotics and supportive measures as necessary (painkillers, fluids, etc), it has been determined that the best course of action is to take preventive measures.

The vaccine against diphtheria is given as a pentavalent vaccine (offers immunisation against 5 diseases: diphtheria, pertussis, tetanus, hepatitis B and Hib-Haemophilus influenza type b). It is given at 1.5, 2.5 and 3.5 months of age. The DPT vaccine (trivalent, covers 3 diseases: diphtheria, pertussis and tetanus) is given between 16 to 24 months of age. When the child is around 6 years old, another booster dose is required. In addition, the Centre has also advised that children be given the Td vaccine (covers tetanus and diphtheria) at age 10 and age 15.  [Byline: Dr Nimeshika Jayachandran]
========================
[Erode, with a population of about 2.25 million residents in 2011, is the largest district in the Indian state of Tamil Nadu, located in the state's westernmost region; its headquarters is the city of Erode (<https://en.wikipedia.org/wiki/Erode_district>).

Diphtheria is caused by toxin-producing strains of _Corynebacterium diphtheriae_, an aerobic Gram positive bacillus. _C. diphtheriae_ causes respiratory tract or cutaneous diphtheria. Toxin production occurs only when the bacillus is infected (lysogenized) by a specific bacteriophage that carries the gene encoding the toxin. The most common sites of diphtheria infection are the pharynx and the tonsils, where an adherent pseudomembrane forms, which may result in respiratory obstruction. The toxin is responsible for the major complications, myocarditis (such as cardiac arrhythmias and heart failure) and neuritis (such as paralysis of the soft palate, eye muscles, limbs, and diaphragm). The overall case fatality rate for diphtheria is 5-10% but is higher (up to 20%) among persons younger than 5 and older than 40 years of age.

Close contacts, especially household contacts, should receive a diphtheria booster, appropriate for age, and antibiotics, such as benzathine penicillin G or a 7-10-day course of oral erythromycin. - ProMED Mod.ML]

[Minnesota] state health officials said [Tue 13 Aug 2019], 3 children are sick from _E. coli_ bacteria after swimming in a Minneapolis lake. The children have tested positive for the same strain of _E. coli_ after swimming at Lake Nokomis beaches between [26 Jul and 2 Aug 2019]. 2 beaches of the lake are closed until further notice, the Minnesota Department of Health said. The children, all under the age of 10, were not hospitalized.

Minneapolis Park Board Superintendent Al Bangoura said it's the 1st time someone has fallen ill after swimming in a Minneapolis lake in more than 20 years. "We take this very seriously and are working closely with the Minnesota Department of Health as they conduct their investigation," Bangoura said in a news release.

Symptoms of illness caused by _E. coli_ bacteria include stomach cramps and diarrhea, with mild or no fever. People typically become ill 1 to 8 days after exposure. It's rare, but the infections sometimes lead to a serious complication involving kidney failure. Health officials say children younger than 10 years old, the elderly, and those with weakened immune systems have a higher chance of developing complications from _E. coli_ infections.

"This is also an important reminder that anyone who is experiencing diarrhoea should not go swimming while they are sick," said Trisha Robinson, waterborne disease supervisor at the Health Department.

Officials also want to hear from anyone else who may have become ill after swimming in Lake Nokomis.

"If there are other people who have gone swimming and are concerned about their symptoms of illness, we very much encourage them to contact their health care providers," Robinson said.
===================
[It is important to understand that there are many different kinds of _E coli_. The organism is an important component of the human intestinal tract and can perform important functions helpful to its host. These strains can cause human infections if they "escape" from the usual location into the urinary tract, gall bladder, or abdominal cavity. They are also what are mentioned when a beach is closed for _E. coli_ contamination. In this circumstance, officials are measuring the organism or "coliforms" in the water to reflect human sewage contamination.

Additionally, there are some strains of _E. coli_ that can produce toxins that can produce diarrhea, and much of so-called travellers' diarrhoea is caused by these strains. All of these strains are human bacteria, not zoonotic organisms, that is, not spread from animal hosts. One _E. coli_ group called Shiga toxin producing or enterohemorrhagic _E. coli_ (EHEC) is the organism likely to be involved here, are zoonotic. Spread in a number of ways, including via undercooked ground beef, contaminated vegetables, and direct or direct contact with farm animals including contaminated water, EHEC can cause significant disease and even death.

In the spring of 2000, in Walkerton, a town of 5000 in southern Ontario, an outbreak of _E. coli_ O157:H7 infection claimed 7 lives -- 6 adults and a child -- and over 200 were seen at local area hospitals.

38 children in France, including babies, living near what was once Europe's largest gold mine have tested positive for arsenic poisoning.

Children in the Orbiel Valley, in the southern department of Aude, were examined when families became concerned that flooding in October last year [2018] had carried arsenic and heavy metals from the nearby Salsigne mine.

After testing 103 children aged under 11 years, the Occitanie Regional Health Agency confirmed on Tue [13 Aug 2019] that 38 of them had returned positive test results for above-average levels of arsenic.

Salsigne, the world's largest arsenic mine, had been operating for almost a century when it closed in 2004. Millions of tons of toxic waste, which local NGOs say have not been properly sealed, are in storage at 5 nearby sites.

In October 2018, 14 people were killed when the Aude was hit by violent floods. Media reports say the Orbiel river and its tributaries have spread pollutants from the old mine.  [Byline: Eric Cabanis]
=========================
[There are a number of ways products can enter the body: inhalation, absorption, ingestion, and injection. Absorption is often thought of as products being absorbed through the GI tract, but it is also most significantly through the skin (such as a bath if arsenic is in the water). The integument (skin) is one of the largest organs of the body.

There are different forms of arsenic. There are 2 forms of inorganic arsenic: the reduced or trivalent arsenic (+3) or arsenite, and the oxidized or pentavalent (+5) form known as arsenate. Both of these forms can be absorbed and accumulated in tissues and body fluids.

There are also organic arsenics, but these are generally regarded as less harmful, by orders of magnitude.

Arsenic is a known carcinogen. The article does not tell us whether the exposure was to organic or inorganic arsenic. The form of arsenic is important with regard to toxicity. We are not told the specific ages of the children or babies. However, children, babies, and even pregnant women metabolize arsenic differently than non-pregnant adults.

Exposure to higher than average levels of arsenic occur mostly in the workplace, near hazardous waste sites, or in areas with high natural levels. At high levels, inorganic arsenic can cause death. Exposure to lower levels for a long time can cause a discoloration of the skin and the appearance of small corns or warts. In the United States, arsenic has been found in at least 1149 of the 1684 National Priority List sites identified by the Environmental Protection Agency (EPA).

Arsenic is a naturally occurring element widely distributed in the earth's crust. In the environment, arsenic is combined with oxygen, chlorine, and sulfur to form inorganic arsenic compounds. Arsenic in animals and plants combines with carbon and hydrogen to form organic arsenic compounds.

Inorganic arsenic compounds are mainly used to preserve wood. Copper chromated arsenate (CCA) is used to make "pressure-treated" lumber. CCA is no longer used in the U.S. for residential uses; it is still used in industrial applications. Organic arsenic compounds are used as pesticides, primarily on cotton fields and orchards.

What happens to arsenic when it enters the environment?
- Arsenic occurs naturally in soil and minerals and may enter the air, water, and land from wind-blown dust and may get into water from runoff and leaching.
- Arsenic cannot be destroyed in the environment. It can only change its form.
- Rain and snow remove arsenic dust particles from the air.
- Many common arsenic compounds can dissolve in water. Most of the arsenic in water will ultimately end up in soil or sediment.
- Fish and shellfish can accumulate arsenic; most of this arsenic is in an organic form called arsenobetaine that is much less harmful.

How might I be exposed to arsenic?
- Ingesting small amounts present in your food and water or breathing air containing arsenic.
- Breathing sawdust or burning smoke from wood treated with arsenic.
- Living in areas with unusually high natural levels of arsenic in rock.
- Working in a job that involves arsenic production or use, such as copper or lead smelting, wood treating, or pesticide application.

How can arsenic affect my health?
Breathing high levels of inorganic arsenic can give you a sore throat or irritated lungs.

Ingesting very high levels of arsenic can result in death. Exposure to lower levels can cause nausea and vomiting, decreased production of red and white blood cells, abnormal heart rhythm, damage to blood vessels, and a sensation of "pins and needles" in hands and feet.

Ingesting or breathing low levels of inorganic arsenic for a long time can cause a darkening of the skin and the appearance of small "corns" or "warts" on the palms, soles, and torso. Skin contact with inorganic arsenic may cause redness and swelling.

Almost nothing is known regarding health effects of organic arsenic compounds in humans. Studies in animals show that some simple organic arsenic compounds are less toxic than inorganic forms. Ingestion of methyl and dimethyl compounds can cause diarrhea and damage to the kidneys.

Several studies have shown that ingestion of inorganic arsenic can increase the risk of skin cancer and cancer in the liver, bladder, and lungs. Inhalation of inorganic arsenic can cause increased risk of lung cancer. The Department of Health and Human Services (DHHS) and the EPA have determined that inorganic arsenic is a known human carcinogen. The International Agency for Research on Cancer (IARC) has determined that inorganic arsenic is carcinogenic to humans.

There is some evidence that long-term exposure to arsenic in children may result in lower IQ scores. There is also some evidence that exposure to arsenic in the womb and early childhood may increase mortality in young adults.

There is some evidence that inhaled or ingested arsenic can injure pregnant women or their unborn babies, although the studies are not definitive. Studies in animals show that large doses of arsenic that cause illness in pregnant females, can also cause low birth weight, fetal malformations, and even fetal death. Arsenic can cross the placenta and has been found in fetal tissues. Arsenic is found at low levels in breast milk.

How can families reduce their risk for exposure to arsenic?
- If you use arsenic-treated wood in home projects, you should wear dust masks, gloves, and protective clothing to decrease exposure to sawdust.
- If you live in an area with high levels of arsenic in water or soil, you should use cleaner sources of water and limit contact with soil. - If you work in a job that may expose you to arsenic, be aware that you may carry arsenic home on your clothing, skin, hair, or tools. Be sure to shower and change clothes before going home.

There are tests available to measure arsenic in your blood, urine, hair, and fingernails. The urine test is the most reliable test for arsenic exposure within the last few days. Tests on hair and fingernails can measure exposure to high levels of arsenic over the past 6-12 months. These tests can determine if you have been exposed to above-average levels of arsenic. They cannot predict whether the arsenic levels in your body will affect your health.

The EPA has set limits on the amount of arsenic that industrial sources can release to the environment and has restricted or cancelled many of the uses of arsenic in pesticides. EPA has set a limit of 0.01 parts per million (ppm) for arsenic in drinking water.

The Occupational Safety and Health Administration (OSHA) has set a permissible exposure limit (PEL) of 10 micrograms of arsenic per cubic meter of workplace air (10 ug/m3) for 8 hour shifts and 40 hour work weeks.

The Nigeria Centre for Disease Control (NCDC) is aware of a suspected outbreak of yellow fever in Ebonyi state and has had a rapid response team supporting Ebonyi state's response since [Tue 30 Jul 2019], in partnership with the World Health Organization (WHO).

Following a report of cases and deaths from fever of unknown origin in Izzi local government area (LGA) in Ebonyi state, the state public health team commenced an investigation. As at [Wed 31 Jul 2019], 3 cases had tested positive for yellow fever at NCDC's national reference laboratory, which triggered an immediate response.

The Ebonyi State Epidemiology Team is leading the response with support from the Nigeria Centre for Disease Control (NCDC), the National Primary Health Care Development Agency (NPHCDA), and the World Health Organisation (WHO). In the course of investigation, it was discovered that between 1 May-7 Aug 2019, there had been cases that fit into the case definition for yellow fever and 20 deaths in Izzi LGA, Ebonyi state, indicating that the outbreak may have been going on for a few months, undetected by local health authorities. It was too late to collect samples for confirmation from these cases.

Immediately [after] it was notified, NCDC deployed a rapid response team to support Ebonyi state with contact tracing, case finding, risk communications, and the management of cases. Detailed analysis and plans are in advanced stages to apply to the international vaccine stockpile to enable a reactive vaccination campaign in Ebonyi state, in response to the cluster of cases.

Yellow fever virus is spread through bites of an infected mosquito. There is no human-to-human transmission of the virus. Yellow fever is a completely vaccine-preventable disease, and a single shot provides immunity for a lifetime. The yellow fever vaccine is available for free in primary health care centres in Nigeria as part of the routine immunisation schedule. Every child is protected for life if vaccinated. We encourage every family to ensure that children receive all their childhood vaccines.

In addition to the vaccine, the public is advised to keep their environments clean and free of stagnant water to discourage the breeding of mosquitoes and to use insecticide-treated mosquito nets as well as screens on windows and doors to prevent mosquito bites. It is important to avoid self-medication. Visit a health facility immediately if you feel ill.

Since September 2017, Nigeria has recorded suspected cases of yellow fever in all states in the country. As at [Wed 31 Jul 2019], 78 cases have been laboratory confirmed in Nigeria in 2019 alone. A multi-agency yellow fever technical working group coordinated by NCDC has been leading the investigation and response to yellow fever cases. The National Primary Health Care [Development] Agency is leading efforts to provide an additional opportunity of vaccination through preventive vaccination campaigns across the country.

Healthcare workers are reminded that the symptoms of yellow fever include yellowness of the eyes, sudden fever, headache, and body pain. If you have these symptoms or notice someone in your community displaying them, please contact your nearest health centre.
=====================
[The yellow fever [YF] virus is endemic in Nigeria, and cases occur there sporadically. This has been an active year (2019) for YF in Nigeria. The previous ProMED-mail post indicated that 930 suspected cases have been reported this year from 1 Jan-30 Apr 2019. There are 332 suspected cases during the April 2019 reporting period, up from 254 suspected cases on 19 Feb 2019. There are 3 new presumptive and 3 new confirmed yellow fever cases during the April 2019 reporting period.

The current focus of transmission is in Ebonyi state. The above report indicates that YF vaccine is available without cost in primary healthcare centers but does not mention if an organized vaccination campaign is underway or being planned, nor the proportion of the Ebonyi state population that is unvaccinated and, hence, at risk for YF. - ProMED Mod.TY]

A stewardess of Israel's El Al airline died Tuesday [13 Aug 2019], following a months-long battle with measles. The 43-year-old stewardess was infected with the measles virus during a flight from New York to Israel 5 months ago.

After she was infected, the stewardess was hospitalized in serious condition at Meir Medical Center in Kfar Saba in central Israel after she was found unconscious and struggling to breathe. During her hospitalization, the stewardess' condition deteriorated, and she was transferred to the quarantine section of the hospital's intensive care wing.

On Tuesday [13 Aug 2019], doctors at Meir hospital declared her death, following the 5-month struggle.  [Byline: Orly Harari]
===========================
[This is a very sad outcome, and our condolences go out to the family of the flight attendant, who worked for El Al, the Israeli national airline. It is not clear whether she contracted the virus in New York, in Israel, or on a flight between the two locations. The flight attendant received only one dose of the measles vaccine when she was a child. It wasn't discovered until later that one dose is only about 93% effective. More recently -- in the USA, starting in 1989 -- children have been given 2 doses, which is about 97% effective, according to the CDC.
