Second Bird Tests Positive For West Nile Virus


May 2, 2012


–Warm weather begins to amplify virus in Sacramento County

Elk Grove, Calif.— The Sacramento-Yolo Mosquito and Vector Control District received confirmation today that an American Crow has tested positive for West Nile virus (WNV) in the Tahoe Park area of Sacramento County. This is the second bird of the 2012 season to test positive for the disease. “With the very warm temperatures we’ve seen recently,West Nilevirus is starting to amplify in our region,” said David Brown District Manager. “While we know WNV is here to stay, this bird is a clear sign and a reminder to all that we need to protect ourselves against mosquitoes and diseases they transmit” added Brown.

Residents are strongly encouraged to report all dead birds by calling the California Department of Public Health hotline at 877-968-2473 or online at Some species of birds such as crows, jays and magpies are very susceptible to the virus and are more likely to die from the infection. Birds are hosts for WNV and mosquitoes transmit the virus by biting an infected bird and then biting a person or other animal.

“Dead bird reports provide important surveillance information to track WNV activity in our area and offer valuable information of where positive mosquito samples and human cases may develop later in the season” said Brown. Lack of dead bird reports decreases the District’s ability to detect higher risk locations and protect public health.


In 2011, 9 deaths and 158 human WNV cases were reported inCalifornia.
