5 more West Nile mosquito samples detected in LA area – Press Telegram

Five additional mosquito samples from the Los Angeles area tested positive for West Nile virus, including detections for the first time this year in the Los Feliz neighborhood of Los Angeles and in Glendale, plus three additional detections in Bellflower, Granada Hills and San Marino, the Greater. The LA County Vector Control District announced today.

This brings to 35 the number of positive mosquito samples in the LA vector district this season, according to the GLACVCD.

The Los Feliz case was detected on July 19, while Glendale’s positive result was detected on July 20.

The positive tests in Granada Hills and San Marino were detected on June 28 and bring the number of cases in each community to four so far this season, most in the district. Whittier also has four positive detections.

Bellflower’s most recent positive test came on June 2, bringing that city’s total to three so far this season.

Less than a month ago, on July 5, the LA vector agency had detected only three positive samples in the district: two in San Marino and one in Bellflower.

According to GLACVCD, West Nile virus is endemic to LA, and warm temperatures may increase virus activity and mosquito populations.

“Mosquitoes can complete their life cycle in less than a week on a water source as small as a bottle cap,” Mary-Joy Coburn, director of communications for GLACVCD, said in a statement Monday.

“We urge all Angelenos to conduct routine property inspections for mosquito breeding sources or contact the district to inspect and treat the source.”

West Nile virus season typically runs from summer to fall, according to the US Centers for Disease Control and Prevention. People get it from the bite of an infected mosquito, which gets the virus when it feeds on an infected bird.

Last year, 148 human cases of West Nile were reported in California, including 17 in LA County.

Seven human cases have been reported in the state this year as of July 29, according to the California Department of Public Health.

Most people infected with the virus do not feel sick, but about 1 in 5 who are infected develop a fever and other symptoms, according to the CDC. About 1 in 150 people infected develops serious, sometimes fatal, disease, CDC data show.

Statewide, 702 mosquito samples tested positive as of July 29, and 49 birds were found dead with the virus, the state health department said. Two sentinel chickens and two horses also tested positive statewide.

Because there is no human vaccine or cure for West Nile virus, the vector agency recommends that residents be proactive in using mosquito repellents, but cautions that not all work equally well.

The CDC recommends products with the active ingredients DEET, Picaridin, IR3535, or oil of lemon eucalyptus as safe and effective against disease-carrying mosquitoes when used according to labels.

The GLACVCD also recommends taking these additional steps:

— Remove standing water in gutters, rain barrels, discarded tires, buckets, watering cans or anything that has held water for more than a week;

— Ensure the correct maintenance of swimming pools, spas and ponds;

— Change the water in pet dishes, birdbaths and other small containers weekly;

— Apply for mosquitofish from your local vector control district for placement in ornamental ponds; e

— Report neglected (green) pools in your neighborhood to your vector control district.
