On August 5, 2019, the Orange County Mosquito and Vector Control District (OCMVCD) has confirmed the first mosquito sample to tested positive for West Nile virus in 2019. The mosquitoes we collected from the City of Orange at El Camino Real Park on July 30,2019. The District has also confirmed 9 birds carrying the West Nile virus but, there are no confirmed cases of West Nile virus infections in humans.
West Nile virus is transmitted to humans via the bite of infected mosquitoes, which become infected when feeding on birds carrying the virus. The City of Yorba Linda offers these helpful tips to prevent mosquito bites:
• Apply and Reapply mosquito repellent to exposed skin before going outdoors;
• Wear repellent that contains DEET, Picaridin, IR3535, or oil of lemon eucalyptus;
• Close all unscreened doors and windows; and
• Wear long-sleeved shirts and long pants in lighter-colored clothing.
Most individuals infected with West Nile virus will not experience any illness. However, others will have flu-like symptoms, such as fever, headache and body aches. In severe cases, people will need to be hospitalized, and in rare cases the disease can be fatal. Young children, the elderly, or individuals with lowered immune systems are at greater risk to experience severe symptoms when infected.
