West Nile virus West Nile virus is a virus in which mosquitoes that cause encephalitis (brain inflammation) or meningitis (brain and spinal cord inflammation) are born. The West Nile virus is stabbed by an infected mosquito and infects humans. Bite the bird carrying the virus and infect mosquitoes. You can not get the West Nile virus from this sick person. Young adults are less likely to be at risk of West Nile virus than elderly people.
