Yellow fever outbreak reported in Brazil.
WHO warned that a large epidemic of yellow fever is possible in Brazil after dozens of suspected deaths from the disease were reported in an area with low vaccination coverage.As of Jan. 13, the Brazil Ministry of Health (MOH) said 133 suspected cases and 38 suspected deaths from yellow fever had been reported since Dec. 18 in Minas Gerais — the first yellow fever outbreak in the inland state since 2002-2003, according to WHO. In response, the MOH sent 735,000 doses of vaccine to Mina Gerais last week, increasing the total number in the state to more than 1 million doses. The ministry recommended that people living in rural areas of the 24 affected municipalities in Minas Gerais get vaccinated. According to WHO, one dose of yellow fever vaccine offers lifetime protection. However, the MOH recommends two doses for people in Brazil: one at age 9 months and another at age 4 years. Travelers wishing to protect themselves from yellow fever should be vaccinated at least 10 days before their trip. The rapid spread of yellow fever could be due to low vaccine coverage in Minas Gerais, and there is concern that the outbreak will cross the border to neighboring states that also have low vaccine coverage but favorable ecosystems for the transmission of the virus, such as Espirito Santo and Bahia, WHO said. These areas were previously considered to be at low risk of transmission and, consequently, yellow fever vaccination was not recommended,” WHO said in a report about the outbreak. “The introduction of the virus in these areas could potentially trigger large epidemics of yellow fever.” The outbreak response includes a house-to-house immunization campaign in rural areas of the affected municipalities of Minas Gerais and preparedness activities in bordering states, according to WHO.source
