Most Birds Dying from West Nile Virus Have Been Found in Tri-Valley

West Nile virus activity is increasing and the Livermore area seems to be hardest hit with 13 of the 17 West Nile virus positive dead birds, and 2 groups of positive mosquitoes.  

The Alameda County Mosquito Abatement District urges residents to be proactive by eliminating sources of water where mosquitoes can breed and protecting themselves from mosquito bites. The District's ongoing mosquito surveillance and larviciding program has been intensified in the area.

Alameda County has seen an increase in West Nile virus positive dead birds
this year compared to last.  Dead birds can be an indication that the virus
is present in an area, particularly dead crows, jays and birds of prey.  If
you come across a dead bird please report it by calling (877)WNV-BIRD or
online.

District Manager Chindi Peavey said, "We need all residents of the county,
especially those in the Livermore area, to check their own front and
backyards for any standing water.  It takes only a tiny amount of water to
breed mosquitoes."

As of July 24th, California has had 791 dead birds, 771 mosquito samples, 14
sentinel chickens, and 15 humans test positive for West Nile virus.  The
bird, mosquito, and human numbers are all higher than this time last year.

Reduce the risk of contracting mosquito-borne diseases by following these
guidelines:

• DUMP/DRAIN standing water on your property because that's where mosquitoes develop.
• DAWN/DUSK is when mosquito activity peaks so limit outdoor activities during this time.
• DEFEND yourself when mosquitoes are biting by wearing long pants and long-sleeved shirts and apply insect repellent containing EPA-registered active ingredients such as DEET, Picaridin, IR3535, and Oil of lemon eucalyptus.
• DOOR/window screens should be in good repair with no tears or holes.
