About Yellow Fever

The yellow fever virus is found in tropical and subtropical areas of Africa and South America. The virus is spread to people by the bite of an infected mosquito. Yellow fever is a very rare cause of illness in U.S. travelers. Illness ranges from a fever with aches and pains to severe liver disease with bleeding and yellowing skin (jaundice). Yellow fever infection is diagnosed based on laboratory testing, a person’s symptoms, and travel history. There is no medicine to treat or cure infection. To prevent getting sick from yellow fever, use insect repellent, wear long-sleeved shirts and long pants, and get vaccinated.

For most travelers, a single dose of yellow fever vaccine provides long-lasting protection, and a booster dose of the vaccine is not needed. However, some travelers may require a booster dose. Talk to your healthcare provider to determine if you may need a dose of yellow fever vaccine or a booster dose before your trip to an area at risk for yellow fever.

In the United States, the vaccine is given only at designated yellow fever vaccination centers. International regulations require proof of yellow fever vaccination for travel to and from certain countries. People who get vaccinated should be given an International Certificate of Vaccination. Also note that the vaccine is to be given at least 10 days before travel to an endemic area.

Visit with a healthcare provider to see if you need a typhoid fever vaccine.
