I was bitten by a mosquito. i am nervous about west nile. i am mid 20's and healthy.?

Minimal risk: Very few mosquitoes carry west nile virus. Very few people bitten by a carrying mosquito develop symptomatic infection, and very few who are infected develop encephalitis, which may be predisposed to by advanced age, immune suppression by underlying illnesses, etc. Your likelihood of getting sick is very low.

Low risk: Most people don’t have sx’s w West Nile virus. Mild sx’s occur in about 20% of people; which can include fever, eye pain, generalized body aches, headaches, feeling really tired, & possible enlarged lymph nodes or rash. About 1% have severe illness which can include neurologic problems. Possible sx’s include: seizures, severe headache w stiffness of the neck, high fever, confusion & weakness.
