summary caption

 

West Nile Virus (WNV) is one of a group of disease-causing viruses that are spread by mosquitoes. Mosquitoes become infected with WNV when they feed on birds which carry the virus. The virus can then be transmitted to humans and other animals through the bite of an infected mosquito. Most people infected with WNV do not feel ill but some will experience mild flu-like symptoms. A smaller percentage of individuals develop serious complications. Hospitalization and even death can result from WNV infection.
