What is the current situation?

The Brazilian Ministry of Health has reported an ongoing outbreak of yellow fever. The first cases were reported in the State of Minas Gerais in December 2016, but confirmed cases have since been reported in the neighboring states of Espirito Santo, São Paulo, and Rio de Janeiro. Cases have occurred mainly in rural areas, with most cases being reported from Minas Gerais state. Some cases have resulted in death. Health authorities in the affected states, with assistance from the Brazilian Ministry of Health, are conducting mass vaccination campaigns among unvaccinated residents of affected areas.

In response to this outbreak, health authorities have recently expanded the list of areas in which yellow fever vaccination is recommended for travelers. Yellow fever vaccination is now recommended in all of Espirito Santo and Rio de Janeiro states, including the city of Rio de Janeiro; São Paulo state, with the exception of the urban area of the city of São Paulo; and a number of municipalities in the state of Bahia.

The Brazilian Ministry of Health maintains a list of all other municipalities in Brazil for which yellow fever vaccination continues to be recommended (not including recently added municipalities). It is located at http://portalsaude.saude.gov.br/images/pdf/2015/novembro/19/Lista-de-Municipios-ACRV-Febre-Amarela-Set-2015.pdf.

Note: because yellow fever vaccination was previously recommended and continues to be recommended in western parts of the states of São Paulo and Bahia, some municipalities in each of these states are included on this older list.

Anyone 9 months or older who travels to these areas should be vaccinated against yellow fever. People who have never been vaccinated against yellow fever should not travel to areas with ongoing outbreaks. CDC no longer recommends booster doses of yellow fever vaccine for most travelers. However, a booster dose may be given to travelers who received their last dose of yellow fever vaccine at least 10 years ago and who will be in a higher-risk setting, including areas with ongoing outbreaks. Because of the ongoing outbreak, travelers to the Brazilian states of Minas Gerais, Espirito Santo, Rio de Janeiro and Sao Paulo (except the city of Sao Paulo), and parts of Bahia state, may consider getting a booster if their last yellow fever vaccination was more than 10 years ago. Travelers should consult with a yellow fever vaccine provider to determine if they should be vaccinated. For more information on booster shots, see “Clinician Information,” below.

Because of a shortage of yellow fever vaccine, travelers may need to contact a yellow fever vaccine provider well in advance of travel.

What is yellow fever?

Yellow fever is a disease caused by a virus spread by mosquito bites. Symptoms take 3–6 days to develop and include fever, chills, headache, backache, and muscle aches. About 15% of people who get yellow fever develop serious illness that can lead to bleeding, shock, organ failure, and sometimes death.

How can travelers protect themselves?

Get yellow fever vaccine:

  • Visit a yellow fever vaccination (travel) clinic and ask for a yellow fever vaccine.
    • You should receive this vaccine at least 10 days before your trip.
    • After receiving the vaccine, you will receive a signed and stamped International Certificate of Vaccination or Prophylaxis (ICVP, sometimes called the “yellow card”), which you must bring with you on your trip.
    • For most travelers, one dose of the vaccine lasts for a lifetime. Consult a travel medicine provider to see if additional doses of vaccine may be recommended for you based on specific risk factors.
    • In rare cases, the yellow fever vaccine can have serious and sometimes fatal side effects. People older than 60 years and people with weakened immune systems might be at higher risk of developing these side effects. Also, there are special concerns for pregnant and nursing women. Talk to your doctor about whether you should get the vaccine.

Prevent mosquito bites:

  • Cover exposed skin by wearing long-sleeved shirts and pants.
  • Use an EPA-registered insect repellent containing DEET, picaridin, oil of lemon eucalyptus (OLE), IR3535, or 2-undecanone (methyl nonyl ketone). Always use as directed.
    • If you are also using sunscreen, apply sunscreen first and insect repellent second.
    • Pregnant and breastfeeding women can use all EPA-registered insect repellents, including DEET, according to the product label.
    • Most repellents, including DEET, can be used on children older than 2 months.
    • Follow package directions when applying repellent on children. Avoid applying repellent to children’s hands, eyes, or mouth.
  • Use permethrin-treated (clothing and gear (such as boots, pants, socks, and tents). You can buy pre-treated clothing and gear or treat them yourself:
    • Treated clothing remains protective after multiple washings. See the product information to find out how long the protection will last.
    • If treating items yourself, follow the product instructions carefully.
    • Do not use permethrin directly on skin.
  • Stay and sleep in screened or air conditioned rooms.
  • Use a bed net if the area where you are sleeping is exposed to the outdoors.
