The Monroe County Health Department has confirmed that a batch of mosquitoes tested positive for West Nile Virus, and residents are urged to avoid areas where mosquitoes are found and take measures to prevent them from breeding around their homes.

The Monroe County Health Department said the sample was collected by the department as part of its Mosquito Surveillance Program.

Routine West Nile virus testing by the Windsor-Essex County Health Unit has "identified positive mosquito pools in our community."
