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 is endemic in many tropical areas of Africa and South America but can be prevented by a vaccine. 

What is my risk?

Speak with one of our Travel Health Specialists to understand the Yellow Fever risk in the region you are visiting.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.



1. Speak to our travel health care professionals as early as possible (preferably 4-6 weeks) before you travel.

2. Vaccinate.

3. Protect yourself from mosquito bites.

More information regarding Yellow Fever is available from the CDC.

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.

What are the symptoms?

Symptoms can take 3 to 6 days to appear. Initial symptoms usually include sudden onset of fever, chills, headache, joint and muscle pain, loss of appetite, abdominal pain, back pain, nausea and vomiting, fatigue, weakness and dehydration. Most patients recover after this stage.

In severe cases, the disease can lead to shock, internal bleeding, jaundice (yellowing of the skin and whites of the eyes) and organ failure. This occurs in about 15% of patients, half of whom will die within 10-14 days.
