What are the symptoms of a West Nile virus infection and when do they occur?
Most people infected with West Nile Virus do not become ill. People with a mild infection may present with fever, headache, eye pain, muscle aches, joint pain, a rash on the trunk, and/or swollen lymph nodes. In severe cases (less than 1% of those infected), symptoms include extreme muscle weakness, inflammation of the brain (encephalitis), paralysis, and coma. In rare cases the infection may be fatal, particularly in the elderly and people with other medical conditions. Symptoms usually occur 5 to 15 days after a West Nile Virus infected mosquito bites a person.
