Yellow Fever

What is yellow fever?

Yellow fever is a disease caused by a flavivirus that is transmitted by the bite of an infected mosquito. It gets its name from the yellowing of the skin and eyes (jaundice) that occurs when the virus attacks the liver.

Yellow fever can be prevented by a vaccine.

What is my risk?

Your risk can depend on many factors including your destination, the time of year (season), the length of your trip, and the types of activities you participate in.The risk is low for most travelers, but it may be higher for those who are going to areas of risk and who are staying for an extended period of time, visiting rural or jungle areas, or participating in outdoor activities such as camping, hiking, cycling or field work.

How is it transmitted?

Yellow fever is spread through the bite of infected mosquitoes, mainly the Aedes species in Africa and the Haemagogus species in South America.Mosquitoes that spread yellow fever typically bite during the daytime, particularly around sunrise and sunset.
