West Nile Virus
West Nile virus (WNV) is most often spread by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. Most people who become infected will not get sick. About 1 in 5 people who get infected will develop symptoms: fever, headache, body aches, joint pain, nausea or rash. Less than 1% of infected people will develop serious neurologic illness. For people who develop severe symptoms, recovery may take weeks to months. Some people will not recover. About 10% of people who develop neurologic illness will die. Symptoms begin between 3 and 14 days after being bitten by an infected mosquito.
