West Nile Virus Update

According to the Orange County Mosquito and Vector Control District (OCMVCD), as of August 3, nine cities have reported West Nile virus-positive mosquito samples and three cities have reported three WNV-positive birds. No humans have been infected and the current risk is considered low, but OCMVCD urges county residents to remain vigilant.

“West Nile virus-positive mosquito samples indicate that the virus is active in Orange County and there is an increased risk for residents to become infected with WNV through a mosquito bite,” said Director of Scientific Services Robert Cummings. West Nile virus is most commonly spread to people by the bite of an infected mosquito. Mosquitoes become infected when they feed on infected birds. There are no confirmed cases of human infections currently in Orange County.  OCMVCD staff will continue to conduct surveillance, inspections and control measures for mosquitoes to prevent additional mosquito breeding. OCMVCD also will post WNV advisory signs alerting residents of high WNV activity in affected areas.  “It is essential for residents to do their part and take charge of their yard,” said Director of Communications Lora Young. “The best way to protect yourself is by applying EPA-registered repellent, wearing long sleeved clothing and eliminating potential breeding sources around your property.”

Village residents should take the following precautions to help reduce the chances of breeding mosquitoes:

  • Dump and drain any containers filled with water at least once a week
  • Clean and scrub bird baths and pet water bowls weekly
  • Dump water from potted plant saucers
  • Do not transport or share plant clippings rooted in water
  • Drill a hole or puncture containers to eliminate standing water
