Share via email

The state has confirmed that mosquitoes collected from several locations in the Murrieta and Temecula area and one location in the Hemet area tested positive for West Nile virus.

The Riverside County Department of Environmental Health received the confirmation after samples were collected Aug. 11 and 12 from locations at Monroe Basin, the northwest corner of Temecula and western Hemet.

It is not unusual for mosquitoes in parts of Riverside County to test positive for the virus, especially during the summer.

In 2013, 81 mosquito samples tested positive for the virus.

The virus can be transmitted to humans and some animals through the bite of an infected mosquito. Most individuals infected will not experience any illness. Others will have only mild symptoms, such as fever, headache and body aches.

 

However, young children, the elderly or individuals with lowered immune systems are at greater risk of more severe symptoms. Anyone with symptoms is advised to contact their health care provider.

The department also advises:

• Protect yourself against mosquito bites by using insect repellent. Use a repellent with DEET (N, N-diethyl-m-toluamide), picaridin (KBR 3023), oil of lemon eucalyptus [p-methane 3, 8-diol (PMD)] or IR3535 according to the instructions on the product label. DEET products should not be used on infants under 2 months of age and should be used in concentrations of 30 percent or less on older children. Lemon eucalyptus oil should not be used on children under age 3.

• Be aware of peak mosquito hours. Dawn and dusk are peak biting times for many mosquitoes. Consider rescheduling outdoor activities planned for those hours.

• Clothing can help reduce mosquito bites. Wear long sleeves, long pants and socks when outdoors to help keep mosquitoes away from skin.

• Mosquito-proof your home. Drain standing water where mosquitos lay their eggs. Limit the number of places for mosquitoes to breed by draining/discarding items that hold water, like old tires. Check rain gutters and drains. Empty unused flowerpots and wading pools. Change water in birdbaths and pet bowls at least weekly.
