SAN BERNARDINO, Calif., July 6 (Inland Empire News Online) — Residents in San Bernardino County are being urged to dump standing water and guard against mosquito bites after county officials said mosquitoes collected in San Bernardino tested positive for West Nile virus.
The San Bernardino County Department of Public Health said the finding was the first positive mosquito collection in the county’s mosquito and vector control service area in 2024.
County public-health messaging said the Environmental Health Services Mosquito and Vector Control Program is taking steps to eliminate mosquito breeding hazards and advised residents to remove standing water around homes and protect themselves from mosquito bites.
The county release did not say whether any human West Nile virus cases had been reported.
West Nile virus is spread by infected mosquitoes, and public-health agencies monitor it through mosquito trapping and testing and by testing dead birds, according to the County of San Diego’s Vector Control Program.
