Recife, Brazil, Nov 4, 2019 (AFP) - Months after thick oil began turning idyllic beaches in Brazil into "black carpets," workers and volunteers wearing rubber gloves race against time to scrape off the remaining fragments ahead of the country's peak tourism season.   Paiva, Itapuama and Enseada dos Corais in the northeastern state of Pernambuco are among hundreds of beaches fouled by an oil spill that began to appear in early September and has affected more than 2,000 kilometers (1,250 miles) of Atlantic coastline.

As ocean currents brought large globs of crude to shore near the capital Recife in recent weeks, locals rushed to the normally picturesque beaches and used their bare hands to remove the toxic material coating sand, rocks and wildlife.    "I was shocked, there were people entering the water without gloves, without safety equipment, in the middle of the oil," coconut seller Glaucia Dias de Lima, 35, told AFP as she picked up chunks of crude from Itapuama beach.

Thousands of military personnel have been dispatched to help clean up the oil that has killed dozens of animals, including turtles, and reached a humpback whale sanctuary off Bahia state that has some of the country's richest biodiversity.   It is the third major environmental disaster to strike Brazil this year. In recent months fires ravaged the Amazon rainforest and in January a mine dam collapsed in the southeast, spewing millions of tons of toxic waste across the countryside.    Wildfires are still raging across the Pantanal tropical wetlands.

While thousands of tons of crude waste have been recovered so far, the space agency INPE said Friday there might still be oil at sea being pushed by currents. It could reach as far south as Rio de Janeiro state, the agency said.   President Jair Bolsonaro warned Sunday that "the worst is yet to come," saying only a fraction of the spilled crude had been collected so far.    The government on Friday named a Greek-flagged tanker as the prime suspect for being the source of the oil slicks.   The ship Bouboulina took on oil in Venezuela and was headed for Singapore, it said. The tanker's operators have denied the vessel was to blame.

- Fishing paralyzed -
As the southern hemisphere's summer approaches, people dependent on the fishing and tourism industries are nervously waiting for test results to show if the water is safe to swim in and eat from.   Northeastern Brazil is a popular tourist destination all year round, but visitor numbers usually explode in the hotter months. 

Eco-tourism guide Giovana Eulina said the disaster would affect the sector and she called for a campaign to "encourage people to come here."   Fishing in the region also has been largely paralyzed by the oil spill, even in areas where crude has not been detected.   "We still don't have a concrete answer from a scientist who says that (the water) is really contaminated," said Sandra Lima, head of a local fishing association.    Edileuza Nascimento, 63, stands in muddy water near Recife and extracts shellfish that she will sanitize at home, freeze and then sell.   It was already a struggle for fishermen to make a living, she said. But the oil slick has been "too much."    "It has come to finish off the fishing families."

Sao Paulo, Oct 31, 2019 (AFP) - Wildfires are raging across the Pantanal tropical wetlands in southern Brazil, one of the most biodiverse areas in the world and a major tourist destination, regional authorities said Thursday.   The governor's office in the state of Mato Grosso do Sul said the fires were "bigger than anything seen before" in the region.    So far, more than 50,000 hectares (nearly 125,000 acres) have been affected.   The blazes follow other wildfires that environmental groups say ravaged millions of hectares in the Amazon rainforest in August.

The statement from the governor's office said the situation was "critical," with blazes ravaging three towns in the Pantanal, a popular eco-tourism spot.   "Intense flames and reddish smoke have disrupted traffic" on the highways, the statement said.   The coordinator of the National Risk Management Center, Paulo Barbosa de Souza, said the blaze -- fed by wind and dry vegetation -- was causing "logistical difficulties."   Satellite images from the INPE space institute showed there were nearly 8,500 fires in the Pantanal area between January and October this year.   That was the worst record since 2007.

Despite successive warnings in recent years, Brazil has not yet managed to stop the advance of syphilis. Last year [2018], the country recorded the largest number of cases of the disease since 2010, when reporting began to occur regularly, according to data from the Ministry of Health.

In 2018 alone, there were 158 000 cases of acquired syphilis, equivalent to 75.8 cases per 100,000 inhabitants. For comparison, a year earlier, this rate was 59.1 cases per 100,000.

Experts reason better detection, but there is also lack of penicillin and a refusal to prevent. Preliminary data from 2019 indicate that the trend is unlikely to reverse this year [2019].

This advance trend is global and worries the World Health Organization, although the organization does not have updated numbers of disease prevalence.

Experts say data represent an improvement in identifying cases through examinations and difficulty in controlling the progress of the disease in the country.  "At least 3 times a week I get test results that show syphilis. Many are from patients who have had treatment but became infected again. Every day this becomes more frequent," said infectious disease specialist Eliana Bicudo, consultant to the Brazilian Society of Infectious Diseases.

According to the Ministry of Health, other factors have contributed to the increase in cases. "There is progress in the disease [increasing incidence], related both to greater detection capacity and the reduction of preventive measures," said the Secretary of Health Surveillance, Wanderson Oliveira. Chief among them, he says, is a reduction in condom use, in a context where people have more [multiple] sexual partners.

Still, according to the secretary, problems in the supply of penicillin in recent years also helped to boost the disease in different countries.  [Byline: Natalia Cancian, Kiratiana Freelon]
=================
[The news report above fails to say much about the epidemiology of syphilis in Brazil, other than that there is an increasing incidence (presumably primary and secondary (P&S) syphilis, the most infectious stages of the disease), although the specific stage of syphilis being reported is not mentioned in the article; in 2018 the reported incidence was 75.8 cases per 100,000 population, the highest since 2010, when reporting began to occur regularly, according to data from the Ministry of Health. The health authorities are attributing this rising incidence to greater detection and decreased condom use, especially among people with multiple sexual partners.

In the US, after syphilis reached historic lows in 2000, with less than 6000 reported cases and an incidence of only 2.1 cases per 100,000 people, the country has since experienced a rising incidence of P&S syphilis. In 2018, 35,063 cases of P&S syphilis were reported, yielding a rate of 10.8 cases per 100,000 population (<https://www.cdc.gov/std/stats18/STDSurveillance2018-full-report.pdf>).

During 2000-2015, the rise in the rate of reported P&S syphilis in the US was primarily attributable to increased cases among men, specifically among gay, bisexual, and other men who have sex with men (MSM). Similar to past years, in 2018, MSM accounted for the majority (53.5%) of all reported cases of P&S syphilis and, of these, 41.6% were known to be living with diagnosed HIV.

Although rates of P&S syphilis are lower among women, rates have increased substantially in recent years, increasing 30.4% during 2017-2018 and 172.7% during 2014-2018, suggesting a rapidly growing heterosexual epidemic (<https://www.cdc.gov/std/stats18/STDSurveillance2018-full-report.pdf>).

The increasing incidence in women has been associated with increasing rates of congenital syphilis. Since 2013, the rate of congenital syphilis has increased each year. In 2018, 1306 cases of congenital syphilis were reported  (<https://www.cdc.gov/std/stats18/STDSurveillance2018-full-report.pdf>).

Similar trends have been seen in other countries (such as Australia, New Zealand, Canada, and Japan), where increases have recently also occurred in the incidence of syphilis among women, accompanied in some countries by increases in congenital syphilis. ECDC reported a similar trend in some western EU/EEA countries, but not in eastern EU countries (<https://ecdc.europa.eu/en/news-events/syphilis-notifications-eueea-70-2010>).

The reasons for the increases in the incidence of syphilis are varied and likely differ by locality and the patient population affected. Increased diagnostic testing for syphilis could contribute to some extent to the increased incidence in some groups, such as MSM. Some of the factors that could promote unprotected (condomless) sex include lack of sex education and access to condoms for teenagers and young adults; the opioid epidemic and sale of sex for drugs; the popularity of cell phone geolocating dating apps that facilitate sexual activity with multiple anonymous partners; use of Internet chat rooms to meet sex partners; use of psychoactive "party drugs"; and use among MSM of pre-exposure HIV prophylaxis, or PrEP, which is a way to prevent HIV infection for people who do not have HIV but who are at substantial risk of getting it by engaging in risky condomless sexual activity (<https://www.cdc.gov/hiv/pdf/PrEP_fact_sheet_final.pdf>).

A CDC study showed that during 2013-2017, when the P&S syphilis rate increased 72.7% nationally in the US and 155.6% among women, the use of methamphetamine, injection drugs, and heroin more than doubled among women and heterosexual men with P&S syphilis. Similar trends have been seen in Canada (ProMED-mail post Syphilis - Canada: (MB) increased incidence, methamphetamine use, 2018 http://promedmail.org/post/20190131.6287056). The data in the US did not reveal the same increases in drug use among gay men with syphilis, the group with the highest rates of the disease.

The linkage of illicit drug 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.

The Teresina Municipal Health Foundation (FMS), through the Neuroinvasive Syndromes Surveillance program, confirmed the 4th case of West Nile fever in the state of Piaui [PI]. This is a female patient who suffered from acute encephalitis, inflammation of the nervous system, in April 2019.

"The FMS is investigating the possibility of a case acquired in Piaui (an indigenous case). This is because the patient was in the municipalities of Cabeceiras, PI and Lagoa Alegre, PI, in the weeks before the illness. She was admitted to the HUT [Teresina Emergency Hospital] and was discharged after treatment, leaving neurological sequelae ", explains FMS neurologist Marcelo Vieira.

West Nile fever virus is transmitted through the bite of an infected mosquito, usually of the _Culex_ genus. Natural hosts are some wild birds that act as virus amplifiers and can be a source of infection for mosquitoes. It can also infect humans, horses, primates, and other mammals. There is no person to person transmission.

"Disease prevention is done through measures to minimize the proliferation and contact of mosquitoes with humans. All suspected cases in Teresina are reported and laboratory investigated for West Nile fever, in partnership with the Central Public Health Laboratory of the Piaui and the Evandro Chagas Institute," concludes Marcelo Vieira.

According to Amariles Borba, FMS Health Surveillance Director, the 1st human case was registered in the municipality of Aroeiras do Itaim, PI, in 2014. "Since then, 2 other cases had been confirmed in the municipalities of Picos, PI and Piripiri, PI, both in 2017. Cases in horses have been detected in the states of Ceara, Espirito Santo, and Sao Paulo," she says.

==================================
[West Nile virus transmission in Piaui and other states in Brazil, beginning in 2014 has continued. The 2014 date is interesting considering that West Nile virus arrived in North America in 1999 and has taken only 15 years or less to reach Brazil. With cases occurring in several states in Brazil in the past 5 years, it is likely that the virus has become established there. The virus has caused cases in South America earlier than that. West Nile virus (WNV) was first reported in South America in equine animals in Colombia in 2004 and in 2006 in horses in Argentina, 5 and 7 years, respectively, after it was introduced into the Americas in New York in 1999. Owners of equine animals would be wise to vaccinate their animals and human prudent to avoid mosquito bites. - ProMED Mod.TY]

In one week, Pernambuco recorded 14 new cases of measles. According to the latest epidemiological bulletin released on Wednesday [9 Oct 2019] by the State Department of Health (SES), the state has accumulated, in 2019, 37 confirmations of the disease. Since the beginning of the year [2019], 799 suspected viruses have been reported in Pernambuco cities. Among the investigated cases, 284 were discarded and 515 are still under evaluation. The state is one of 16 federation units with active disease outbreak in Brazil.

The municipalities with confirmed measles cases in Pernambuco are as follows: Northern Taquaritinga (14), Caruaru (6), Strands (5), Recife (3), Capibaribe Holy Cross (3), Toritama (3), Calves (1), Friar Miguelinho (1), Jaboatao of the Guararapes (1).

Despite the significant number of new confirmations, the state secretary of health, Andre Longo, considers that the new cases included in the newsletter are old. "These are people who fell ill between July and August [2019]. All measures to treat patients and investigate and block new cases are implemented soon after notification," he says.

According to the secretary, regardless of the positive result after laboratory tests, suspected cases are treated as if it were a confirmed case. The intention, according to the SES, is to prevent sequelae and deaths in patients and death and minimize the possibility of contagion. With the strengthening of vaccination, until 4 Oct [2019], 507 814 people were immunized with the triple virus in Pernambuco.

Among the number of vaccinated patients, 215 986 doses were administered to children between 6 months and 4 years. The figures also reveal that the state was able to achieve 98% coverage in the 1st dose of the triple virus in one-year-olds. In the 2nd dose, which should be done 3 months after the 1st dose, the coverage is lower: 74.5%.

According to the Ministry of Health, children are the most susceptible to complications and deaths from measles, since the incidence of cases in children under one year is 9 times higher than the general population. The 2nd-most-affected age group is 1-4 years.

Since the 2nd half of August [2019], immunization of infants between 6 months and 11 months with the triple virus has been instituted throughout Brazil. Until then, the vaccination schedule of the 3 diseases began only after the 1st year. After administration of the "zero dose," it will still be necessary to follow the basic vaccination schedule from 12 months, with one more dose and a booster at 15 months.

Little coverage of 2nd dose of vaccine in children is still worrying in Pernambuco Although Pernambuco has already reached the minimum target of vaccination of the 1st dose of the triple viral in children up to 12 months, the index was not reached in the set of municipalities of I and VIII Regional Health Management (Abreu e Lima, Aracoiaba, Cabo de St. Augustine, Camaragibe, Big Ch, Tea of Joy, Glory of Goita, Fernando de Noronha, Igarassu, Ipojuca, Itamaraca, Itapissuma, Jaboatao of the Guararapes, Moreno, Olinda, Paulista, Pigeons, Reef, Sao Lourenco da Mata Antao, Afranio, Cabrobo, Sleepers, Big Pond, Oroco, Petrolina, Santa Maria da Boa Vista).

"These are populated areas that have a large circulation of tourists all the time. That is why the importance of intensifying actions and actively searching to avoid pockets of unprotected children," points out the superintendent of immunization of the State Department of Health (SES-PE), Ana Catarina de Melo. According to her, regarding the 2nd dose of the vaccine, considered essential for the protection of children, only the Geres de Palmares and Salgueiro were able to reach the minimum target of 95%.

Children between 6 months and under one year old, residing in the following 9 municipalities, should [get vaccinated] take one dose of the triple viral: Recife, Paulista, Calves, Caruaru, Santa Cruz do Capibaribe, Taquaritinga do Norte, Vertentes, Friar Miguelinho, and Salgueiro. Importantly, these children will need to follow the normal immunization schedule from 12 months.

At the moment, vaccination is still indicated for children from 6 months to under one year who are going to move to municipalities with an active measles outbreak. Immunization must be done at least 15 days before travel.
