West Nile Virus

West Nile Virus (WNV) is transmitted through the bite of an infected mosquito. Most people infected with WNV do not show symptoms. Others can get fever, head and body aches, fatigue, rash, meningitis or encephalitis. Exposure to WNV can be prevented by reducing mosquito development sites (i.e., standing water) and using personal protection against mosquitoes.
