West Nile Virus Weekly Update: 9/11/15

West Nile virus continues to be active! Most WNV cases occur during these hot summer months. We urge you to remain vigilant and keep mosquitoes out of your yard and protect yourself from mosquito bites.

The Greater Los Angeles County Vector Control District (GLACVCD) confirmed West Nile virus activity for the first time this year in the following cities or communities:

  • Canoga Park
  • Los Feliz
  • Winnetka

Year to-date, GLACVCD has confirmed West Nile virus activity in:

  • 52 cities/communities
  • 112 mosquito samples
  • 5 dead birds
  • 4 sentinel chickens

Please visit our West Nile virus statistics page for more information.

GLACVCD encourages residents to take the following safety precautions to protect against mosquito-borne diseases:

  • Eliminate or manage all sources of standing water to discourage mosquito breeding every week. The work residents do now will make a big difference.
  • If you are outdoors when mosquitoes are biting, wear long pants and long-sleeved shirts and use an insect repellent containing EPA-registered active ingredients such as DEET, Picaridin, IR3535, and Oil of lemon eucalyptus (PMD). Always apply according to label instructions.
  • Make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or holes.
  • Contact us at 562-944-9656 or visit glacvcd.org if there is a significant problem or potential mosquito breeding source where you live or work.

These symptoms can last for several weeks to months. One in 150 people infected with the virus will become extremely ill.
