Risk for travelers

Yellow fever occurs in urban and rural areas of Africa and central South America. You should get vaccinated for yellow fever before visiting areas where yellow fever is common. Travelers should also take precautions against mosquito bites when in areas with yellow fever transmission. If you continue to live or travel in yellow fever-endemic areas, you should receive a booster dose of yellow fever vaccine every 10 years. Yellow fever vaccine is highly effective.

Yellow Fever Vaccine Recommendations

Yellow fever vaccine is recommended for people over the age of 9 months who are traveling to or living in areas at risk for yellow fever virus transmission in South America and Africa. Yellow fever vaccination requirements and recommendations for specific countries are available on the CDC Travelers' Health page. If you get vaccinated for yellow fever you should be given an International Certificate of Vaccination. Also note that the vaccine is to be given 10 days before travel to an endemic area.

What is yellow fever?

Yellow fever is a viral hemorrhagic fever transmitted by infected mosquitoes. Infection causes a wide range of severity, from mild symptoms to severe illness and death. The "yellow" in the name is explained by the jaundice that affects some patients, causing yellow eyes and yellow skin.

Yellow Fever Transmission

In jungle and forest areas, monkeys are the main reservoir of infection. These mosquitoes bite during daylight hours. In urban settings mosquitoes transmit the virus from human-to-human and introduction of infection into densely populated urban areas can lead to large epidemics of yellow fever.

Yellow fever virus is related to West Nile, St. Louis encephalitis, and Japanese encephalitis viruses.

Yellow Fever Symptoms

Although most infections are asymptomatic, some lead to an acute illness characterized by two phases. Initially, there is fever, muscular pain, headache, chills, anorexia, nausea or vomiting, often with a slowed heart rate. After a brief remission of a few hours to a day, some cases progress to a more severe form of the disease with high fever, jaundice, bleeding, then shock and multiple organ failure. Up to half of these patients die within 2 weeks of the onset of illness.
