Yellow fever is an acute viral hemorrhagic fever that is spread through the bites of infected mosquitoes.
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.
There are no medications to treat or cure yellow fever. To prevent getting sick from yellow fever, use insect repellent, wear long-sleeved shirts and long pants, and get vaccinated.
