West Nile Virus in Dead Birds and Tree Squirrels - 2012
In 2012, a total of 274 dead birds and
15
dead tree squirrels tested positive for West
Nile Virus (WNV) in LA County.
WNV is transmitted to humans, horses, and
birds by the bites of infected mosquitoes. Testing dead
wild birds for WNV
provides a way
of
tracking the virus in our environment. Veterinary Public
Health works with the California Department of Public
Health and local mosquito control agencies in conducting WNV surveillance in Los Angeles County.
As always, many thanks to Los Angeles County residents,
Animal Control Agencies, wildlife rehabilitators, and Vector Control Agencies for
all of your work on WNV surveillance!
