The Greater Los Angeles County Vector Control District has confirmed 13 additional mosquito samples that tested positive for West Nile virus.

This brings the total number of positive samples within the District’s service area to 76 this year.

This is the first detection of the virus this year in the following communities: Canoga Park, Downey, Eagle Rock, Elysian Valley, Los Angeles city and Winnetka.

West Nile virus is endemic to Los Angeles County, and warm temperatures can increase virus activity and mosquito populations. Visit VectorSurv Maps or WestNile.ca.gov for a comprehensive look at this year’s West Nile virus activity throughout Los Angeles County and Southern California.

Mosquito control is a shared responsibility and residents must take an active role in reducing the threat of mosquitoes and mosquito-transmitted diseases in their neighborhoods by taking the following steps:

–Eliminate standing water in clogged rain gutters, rain barrels, discarded tires, buckets, watering troughs or anything that holds water for more than a week.

–Ensure that swimming pools, spas, and ponds are properly maintained.

–Change the water in pet dishes, birdbaths, and other small containers weekly.

–Request mosquitofish from your local vector control district for placement in ornamental ponds.

–Wear EPA-recommended insect repellent when outdoors where mosquitoes may be present.

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