Word! Yellow Fever
Say: YEL-oh FEE-vur
Yellow fever is caused by a virus carried by mosquitoes. It’s usually found only in tropical parts of Africa and South America. Most people who are bitten by an infected mosquito don’t get sick. People who do might have a fever or headache, throw up, and get jaundice, which turns the skin yellow and gives the fever its name.
Most people with yellow fever get better with no problems. There is a vaccine to prevent yellow fever if you are travelling to places where the disease is common.
