Elk Grove is the latest community where increased West Nile virus activity has raised the prospect of aerial spraying for mosquitoes.
West Nile virus activity is intense and widespread in Sacramento and Yolo counties, and Elk Grove requires close monitoring, officials with the Sacramento-Yolo Mosquito and Vector Control District said Monday. If more virus activity is detected, aerial spraying to control mosquitoes infected with the virus may be necessary, they said.
Laboratory testing results available later this week will help make a determination, according to a district news release.
Last week, the California Department of Public Health announced that the year’s first death related to West Nile virus in California was in Sacramento County. In addition, officials are awaiting confirmation of nonfatal cases from the county Division of Public Health.

Neuroinvasive cases of the virus may cause symptoms such as headache, high fever, neck stiffness, coma, paralysis and seizures. To date, officials said, 10 human cases have been confirmed statewide, including two in Yolo County.
In addition to the confirmed human case in Sacramento County, 340 mosquito samples and 342 dead birds have tested positive for West Nile virus this year.
In Yolo County, 165 mosquito samples and 48 dead birds have tested positive.
