Elk Grove, Ca.—The Sacramento-Yolo Mosquito and Vector Control District has confirmed that the first dead birds of the season have tested positive for West Nile virus. The three nestling Scrub Jays were collected from Galt in South Sacramento County. This is the first indication of West Nile virus activity for the 2021 season. “Finding the first indication of West Nile activity is always significant because it provides an early warning,” said Gary Goodman, District Manager.  “It confirms that the virus is present, shows us where we may find positive mosquito samples and where human cases may develop later in the season” added Goodman. This is the first evidence of the virus within the District’s service area; however neighboring San Joaquin County also reported finding their first positive bird more than a week ago. 
The public is encouraged to report dead birds by calling the California Department of Public Health hotline at 877-WNV-BIRD (877-968-2473).  Some species of birds such as crows, jays and magpies are very susceptible to the virus. Though not all birds that are reported will be picked up and tested, the reports provide valuable information and assist with mosquito surveillance and control efforts that help protect public health.
In response to the detection of WNV activity, the District will increase its mosquito trapping and surveillance in the area to find sources where mosquitoes may be breeding.
