What is yellow fever?
Yellow fever is a severe viral disease spread through the bites of infected mosquitoes. Symptoms can include fever, chills, headache, backache, and muscle aches. In some people, the illness can progress to liver disease, bleeding, shock, organ failure, jaundice, and death.
Yellow fever vaccine is the best protection. Diagnosis is based on symptoms, laboratory testing, and travel history, and there are no medications that cure yellow fever.
