Yellow fever is a serious, potentially deadly flu-like disease spread by mosquitoes. It’s characterized by a high fever and jaundice. Jaundice is yellowing of the skin and eyes, that is why this disease is called yellow fever. In most cases, symptoms include fever, chills, loss of appetite, nausea, 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 comes back, abdominal pain occurs, and liver damage begins causing yellow skin. If this occurs, the risk of bleeding and kidney problems is also increased.

The disease is caused by the yellow fever virus and is spread by the bite of an infected female mosquito.

A safe and effective vaccine against yellow fever exists, and some countries require vaccinations for travelers.
