The Sacramento-Yolo Mosquito and Vector Control District will step up ground treatments for mosquitoes around area parks in Davis, Woodland, Knights Landing and Dunnigan as the ongoing battle against West Nile virus continues.
Aerial treatments are planned for known agricultural sources, district officials announced Friday.
“We are seeing very high levels of West Nile Virus activity in both populated and rural ares of (Yolo) county and we are very concerned,” Gary Goodman, district manager, said in a news release.
In laboratory surveillance results obtained Friday, 16 new Yolo County mosquito samples tested positive for West Nile virus. A total of 56 mosquito samples and 16 dead birds have tested positive for the disease so far this year.
In the Davis area, positive samples were found in Pioneer and Westwood parks, El Macero, North Davis Farms and on Oakside Drive in Willowbank.
The ground and aerial treatments are expected to “quickly reduce the infected mosquito population,” according to the release. Additionally, the district recommends using insect repellent and draining stagnant water, where mosquitoes can breed, from around the home.
West Nile virus is spread by mosquitoes. Many people infected with the virus don’t experience any signs or symptoms, or may experience only minor ones, such as fever or mild headache. However, some people who become infected develop a life-threatening illness that includes inflammation of the brain.
