Orange County’s first West Nile Virus (WNV) positive mosquito sample of the season was identified last week in Garden Grove through routine trapping and testing by the Orange County Mosquito and Vector Control District (OCMVCD). No human infections have been identified so far this season in Orange County. Human infections, as well as WNV positive mosquitos and/or dead birds, have already been identified in the surrounding counties of Los Angeles, Riverside, and San Bernardino.
