Orange County’s first West Nile Virus (WNV) positive mosquito sample of the season was identified through routine trapping and testing by the Orange County Mosquito and Vector Control District (OCMVCD). The sample was identified last week in La Habra. WNV positive mosquito samples have also been identified in Riverside County this year. No human infections of WNV or SLEV have been identified so far this season in Orange County.
