WEST NILE VIRUS DETECTED IN ORANGE COUNTY CITIES
Earlier this week, confirmed new positive mosquito samples infected with West Nile Virus (WNV) in the cities of Anaheim, Buena Park, Fullerton, Huntington Beach, Los Alamitos, and La Habra. This now brings the total number of cities with positive mosquito samples to 15 cities in Orange County.
Residents are encouraged to take precautions and wear mosquito repellent when WNV mosquitos are most active (dawn/dusk), specifically repellent containing DEET, Picaridin, IR3535, or oil of lemon eucalyptus.
Additional precautions include:
• Wear light-colored, loose-fitting, long-sleeved shirts, and long pants while outside at dawn and dusk.
• Dump and drain containers holding standing water at least once a week.
• Clean and scrub bird baths and pet water bowls.
• Close all unscreened doors and windows to prevent mosquitoes from entering your
home or space.
• Repair broken or damaged screens.
