Reduce Risk of Exposure to West Nile Virus

As of August 16, the Orange County Mosquito and Vector Control District (OCMVCD) confirmed a case of West Nile Virus (WNV) human infection in Orange County.

WNV is transmitted to humans via the bite of infected mosquitoes, which become infected when feeding on infected birds. Most people infected with WNV experience no illness but some experience flu-like symptoms, including fever, headache and body aches. Severe cases might require hospitalization. Although extremely rare, the disease can be fatal. Those at a higher risk for severe symptoms include young children, the elderly, or those with lowered or compromised immune systems.

Reduce your risk of exposure by taking preventive measures to avoid mosquito bites. OCMVCD offers the following tips:

  • Dump and drain outdoor containers filled with water at least weekly.
  • Clean out and scrub bird baths and pet water bowls weekly.
  • Dump standing water from potted plant saucers.
  • When going outdoors, apply mosquito repellents to exposed skin; reapply as recommended by the product manufacturer.
  • Choose repellent containing DEET®, Picaridin, IR3535 or lemon eucalyptus oil.
  • Keep unscreened doors and windows closed so mosquitoes do not enter your home; repair broken or damaged screens.
  • Outside, wear long-sleeved shirts and long pants; choose lighter colored clothing.

OCMVCD urges Orange County residents to report unusual numbers of mosquitoes or day-biting mosquitoes. For more information, call 714-971-2421 or 949-654-2421, or click here.
