Davis may be the next community targeted for aerial spraying for mosquitoes to combat the spread of West Nile virus.

West Nile virus activity has been on the rise in Yolo County in recent weeks and the current area of concern is Davis, according to officials with the Sacramento-Yolo Mosquito and Vector Control District.

“This season we are seeing a much higher abundance of mosquitoes than in previous years and many of them are infected with West Nile, putting residents at higher risk,” Gary Goodman, district manager, said in a written statement. “At this moment we are considering aerial spraying to quickly reduce the amount of mosquitoes and protect public health.”

In past weeks, the district has intensified control efforts by conducting ground treatments in area parks and neighborhoods where West Nile virus activity was detected, officials said. It also has carried out aerial treatments of known agricultural sources around the city to create a buffer area and keep the virus from increasing among mosquito populations.

Laboratory testing results will be available Thursday, and officials will make a decision then regarding aerial spraying over Davis, which could occur as early as next week, according to a district news release.

District officials said they will continue to work with local elected officials to keep residents informed of aerial spraying plans.

The Yolo County Public Health Department last week confirmed two human cases of West Nile virus. In addition, 124 mosquito samples and 39 dead birds have tested positive for the disease in Yolo County.

In Sacramento County, one human case of West Nile virus has been confirmed and six others are under investigation, officials said. In addition, 302 mosquito samples and 316 dead birds have tested positive for the virus so far this year.
