NEWPORT BEACH, CA – Health officials have confirmed the first positive detection of West Nile virus in Orange County this year after testing a batch of mosquitoes collected in Newport Beach.
Location of the Detection
According to the Orange County Mosquito and Vector Control District (OCMVCD), the infected mosquitoes were trapped in a specific area bounded by:
- Campus Drive
- Jamboree Road
- State Route 73
- John Wayne Airport
As of Tuesday’s announcement, no human cases of West Nile virus have been reported in Orange County this year.
Early Regional Activity
District officials noted that this is an early positive detection but aligns with recent virus activity seen in neighboring Southern California counties. The regional weather conditions remain highly favorable for sustained mosquito and virus activity.
In response, district personnel are placing advisory signs in the affected Newport Beach neighborhood and stepping up local mosquito surveillance and control efforts.
How Residents Can Protect Themselves
The virus is primarily transmitted to humans through the bite of an infected mosquito. Public information officers emphasize that eliminating breeding grounds is the most effective defense.
Local residents are urged to take the following precautions:
- Dump Standing Water: Empty containers, pet bowls, and clean bird baths at least once a week.
- Use Repellent: Apply insect repellents containing DEET, picaridin, IR3535, or oil of lemon eucalyptus.
- Secure Homes: Repair any holes or tears in window and door screens.
- Dress Appropriately: Wear long sleeves and pants during peak mosquito hours at dawn and dusk.
