Yellow fever

Yellow fever is a viral disease of typically short duration. In most cases, symptoms include fever, chills, loss of appetite, , muscle pains—particularly in the back—and headaches. Symptoms typically improve within five days. In about 15% of people, within a day of improving the fever recurs, pain occurs and liver damage begins, causing yellow skin. If this occurs, the risk of bleeding and kidney problems is increased.
