Yellow Fever

What is Yellow Fever? 
Yellow fever is named for the characteristic jaundice (yellow eyes and skin) that results from viral invasion of liver cells in severe cases. Infected mosquitoes spread the disease from person to person when they bite. Most cases are mild, beginning with sudden headaches, fever and exhaustion but some cases can be more severe and fatal.

Countries of Risk: 
The disease is carried by some species of mosquitoes in Central and South America, and in tropical regions of Africa.

Preparations for Travel to Risk Areas & Recommended Immunizations: 
Yellow fever vaccine consists of a single injected does, given at least 10 days before your departure date. It is effective for 10 years. Since the rare severe case can be fatal and the vaccine is highly effective, your health care provider may recommend vaccination if you are traveling to an area of yellow fever risk. Proof of yellow fever vaccination may be required for entry to some countries.
