Seven chickens from sentinel flocks in Fontana and San Bernardino, combined, have tested positive for West Nile Virus (WNV). Although chickens are not harmed by this virus, it shows the mosquito populations in the area are infected with the virus. This increases the public’s risk of being infected with West Nile Virus. In addition, a group of 14 mosquitoes collected in Fontana, Rialto, and Redlands tested positive for the virus. These are the first chickens and mosquitoes that tested positive in 2017 within the area served by the Division of Environmental Health Services Mosquito and Vector Control Program (MVCP). MVCP is taking steps to eliminate mosquito breeding hazards. View the News Release.
