West Nile Virus Environmental Surveillance in Los Angeles County
The Los Angeles County Department of Public Health conducts a range
of environmental surveillance projects to further our understanding
of local West Nile virus (WNV) activity. Bird Surveillance
Bird Surveillance: West Nile infected dead birds are indicators of the virus presence. In 2004, viral positive dead birds were recovered from nearly all areas of Los Angeles County. Since then, collection, testing, and documentation of WNV positive dead birds have been ongoing. To learn what type of birds to report see our
flyer. Please report dead birds to the State of California's West Nile Virus program at 1-877-WNV-BIRD (1-877-968-2473) or by the
Internet. See the most up-to-date map of WNV positive dead bird data
in Los Angeles County

Mosquito Surveillance
Mosquito Surveillance: Like infected dead birds, mosquito
surveillance programs operated by Mosquito Abatement
Districts statewide help identify the WNV transmission
cycle before human cases occur. Mosquito pools
comprising of 10 to 50 mosquitoes are trapped and tested
for the presence of several mosquito-borne viruses
including WNV. For the most up-to-date map of WNV
positive activity,

Reporting Mosquito Breeding Sites and Areas With Water Accumulation
Acute Communicable Disease Control is responsible for monitoring and addressing human
health problems in Los Angeles County, but is not directly involved with mosquito control
activities. This important action is under the control of the county’s five independent
mosquito control (abatement) districts. Beyond our county, the Health Departments of
Long Beach and Pasadena also operate their own mosquito control programs.
To report a potential mosquito breeding situation:
please contact the appropriate Mosquito Abatement District or city
public health department:
