West Nile Virus (WNV) has been detected in two American Crows in East Long Beach, near El Dorado Park. The birds were tested by the State Department of Public Health’s WNV Surveillance System, which monitors the disease in humans, horses, chickens, mosquitoes and dead birds. This year (2013), WNV activity has been detected in 20 counties in California, including WNV positive birds and mosquitoes in Los Angeles and Orange Counties.

No human cases of WNV have been detected in Los Angeles or Orange Counties; however, one human WNV case was detected in Sacramento earlier this year. In 2012, 479 human WNV cases, including 20 deaths, were reported in California. Long Beach had no WNV deaths in 2012, and only one human WNV case reported.

The WNV infected birds were found in the section of the City served by the Greater Los Angeles Vector Control District (GLAVCD). The Long Beach Health Department has confirmed that GLAVCD will be increasing surveillance and treatment of active mosquito breeding areas. The Long Beach Health Department Vector Control Program, which serves the western portion of the City, will also be increasing surveillance and treatment services in response to this information.

Report dead birds and dead tree squirrels to the California Department of Public Health by calling 1-877-WNV-Bird. For further information, contact the City of Long Beach Health Department, Vector Control Program, at 562.570.4132 or online at and click on “West Nile Virus.”
