The Greater Los Angeles County Vector Control District has confirmed seven additional samples of mosquitos testing positive for West Nile virus, or WNV.

This brings the total number of samples positive for the virus within the district’s service area to 13 this year.

The new positive samples were collected from six new areas: Winnetka, West Hills, Canoga Park, Granada Hills, La Mirada and Cerritos.

No infected samples have been reported in the Santa Clarita Valley so far this year.

Mosquito control is a shared responsibility and residents must take an active role in reducing the threat of WNV 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.

West Nile virus is endemic in Los Angeles County, and the summer heat can increase virus activity and mosquito populations So far this year, 10 WNV human cases have been reported in California, two of which were identified by the Los Angeles County Department of Public Health.
