Yellow Fever in Brazil
Alert - Level 2, Practice Enhanced Precautions
Key Points
There is a large, ongoing outbreak of yellow fever in multiple states of Brazil. Since early 2018, a number of unvaccinated travelers to Brazil contracted yellow fever; many of these travelers were infected on the island of Ilha Grande (Rio de Janeiro State). Several have died.
Travelers to Brazil should protect themselves from yellow fever by getting yellow fever vaccine at least 10 days before travel, and preventing mosquito bites.
In addition to areas in Brazil where yellow fever vaccination has been recommended since before the recent outbreaks, the vaccine is now also recommended for people who are traveling to or living in: All of Espirito Santo State, S?o Paulo State, and Rio de Janeiro State as well as a number of cities in Bahia State.
People who have never been vaccinated against yellow fever should avoid traveling to areas of Brazil where yellow fever vaccination is recommended.
Travelers going to areas with ongoing outbreaks may consider getting a booster dose of yellow fever vaccine if it has been 10 or more years since they were vaccinated.
Yellow fever vaccine is available at a limited number of clinics in the United States, so travelers should plan ahead to get the vaccine.
What is yellow fever?
Yellow fever is caused by a virus that is spread through mosquitoes. Symptoms of yellow fever (fever, chills, headache, backache, and muscle aches) take 3?6 days to develop. About 15% of people who get yellow fever develop serious illness including bleeding, shock, organ failure, and sometimes death.
What is the current situation?
In early 2017, the Brazilian Ministry of Health reported outbreaks of yellow fever in several eastern states, including areas where yellow fever was not traditionally considered to be a risk. Since the end of 2017, yellow fever cases have reoccurred in several states, especially in the states of Rio de Janeiro, Minas Gerais, and S?o Paulo, including areas close to the city of S?o Paulo.
In early 2018, a case of yellow fever was reported in an unvaccinated Dutch traveler who had stayed near the S?o Paulo metropolitan region. Since then, there have been reports of other unvaccinated travelers to Brazil who visited areas with yellow fever outbreaks and contracted yellow fever; many of these travelers were infected on the island of Ilha Grande (Rio de Janieiro State). Several of these travelers died. None were from the United States.
In response to the outbreak that began in early 2017, the World Health Organization has expanded the list of areas where yellow fever vaccination is recommended for international travelers to Brazil.
In addition to areas in Brazil where yellow fever vaccination has been recommended since before the recent outbreaks, the vaccine is now also recommended for people who are traveling to or living in:
All of Espirito Santo State
All of S?o Paulo State, the city of S?o Paulo and all coastal islands
All of Rio de Janeiro State, including the city of Rio de Janeiro and all coastal islands
A number of cities in Bahia State
The Brazilian Ministry of Health maintains a regular list of all other cities in Brazil for which yellow fever vaccination has been recommended since before the recent outbreaks. This list does not include recently added areas above. It is located at http://portalsaude.saude.gov.br/imag...a-Set-2015.pdf...
