Yellow fever is a disease caused by a virus that is spread through 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.

Travelers to certain parts of South America and Africa are at risk for yellow fever. For specific information about the country where you are traveling, you may reference Yellow Fever Vaccine Recommendations by Country (CDC website).
