An American crow found in Sacramento County’s Rosemont area has tested positive for West Nile virus, an early warning sign of this year’s virus activity, according to the Sacramento-Yolo Mosquito and Vector Control District.
“It confirms that the virus is present, provides a good indication of where we may find positive mosquito samples and where human cases may develop later in the season,” Gary Goodman, district manager, said in a written statement.
Higher than normal temperatures for this time of year as well as stagnant water left by heavy rains during the winter are expected to result in a busy mosquito season, according to a district news release. Nine other counties statewide have reported West Nile virus activity to date, including one human case.
The public is encouraged to report dead birds by calling the California Department of Public Health hotline at 877-968-2473. Bird species such as crows, jays and magpies are particularly susceptible to the virus.
Never miss a local story.
In response to the detected West Nile virus activity, the district will increase mosquito trapping and surveillance in the area to find where mosquitoes may be breeding.
Residents can help avoid mosquito bites and limit West Nile virus activity by draining standing water that may produce mosquitoes, avoiding being outdoors at dawn or dusk, wearing long sleeves and pants when outdoors and using an effective insect repellent. People also are advised to make sure door and window screens are in good condition.
