A dead American crow found near Folsom Boulevard in East Sacramento has tested positive for West Nile virus, the Sacramento-Yolo Mosquito and Vector Control District confirmed Friday. This was the first dead bird the district has collected this season to test positive for the disease.

“Finding the first positive bird of the season is significant because it serves as an early warning sign that West Nile virus is active in our region,” district manager Gary Goodman said in a press release. “It confirms that the virus is present and helps us identify areas where we may later detect infected mosquitoes or even human cases.”

West Nile detected in Sacramento mosquitos. What to know

On Wednesday, the district confirmed its first mosquito sample of the season had tested positive for the disease. The sample was collected south of Tahoe Park. The West Nile virus has also been reported in Alameda and Santa Clara counties this year.

A busy mosquito and West Nile virus season seem to be ahead. A late spring rain followed by an early stretch of very hot temperature has helped mosquitoes thrive. People should have insect repellent before heading into the the Memorial Day holiday weekend, the district said.

“Whether you’re attending a backyard barbecue, heading out on a camping trip, or enjoying other outdoor activities, it’s important to protect yourself from mosquito bites by using an effective insect repellent,” Goodman said.

The district asks the public to report any dead birds found by calling the California Department of Public Health hotline at 877-968-2473. Not all samples will be retrieved, but the reports all still helpful. Birds like crows, jays and magpies are very susceptible to the virus, while others are not.

As for mosquitos, the district plans to increase trapping and surveillance to find where they may be breeding. To report mosquito problems, call 1-800-429-1022.
