The West Nile virus has been confirmed in mosquitoes in Amherst, the Erie County Health Department said Monday.
The health department also "highly suspects" other areas in Western New York have mosquitoes carrying the virus, the health department said in a news release.
West Nile virus is an illness transmitted through a bite from an infected mosquito. There are no medications to treat or vaccines to prevent the infection. About one in five people who are infected develops flu-like symptoms. In a small number of cases, the infection can cause a more serious, even fatal, illness.
The virus was detected in testing by the state Department of Health.
Health officials recommend all residents take measures to protect themselves by limiting time outdoors around dusk and dawn. Individuals should cover as much skin as possible with clothing when going outside, as well as use insect repellent with 25 to 30 percent DEET on exposed skin.
