Yellow fever is an acute viral hemorrhagic fever.
Symptoms of yellow fever (fever, chills, headache, backache, and muscle aches) develop 3-6 days after infection. About 15% of people infected with yellow fever virus will develop severe illness that can lead to liver disease, bleeding, shock, organ failure, yellowing skin (jaundice), and sometimes death.
Diagnosis is based on symptoms, laboratory testing, and travel history. Yellow fever virus spreads through the bites of infected mosquitoes.
There are no medications to treat or cure yellow fever. Yellow fever vaccine is the best protection against this disease.
