First West Nile Virus sample found in Yolo County after Woodland mosquito tests positive

West Nile virus has been detected in Yolo County for the first time this year, local mosquito and vector control officials said Wednesday.

The mosquito sample of West Nile virus was collected in Woodland, according to the Sacramento-Yolo Mosquito and Vector Control District

Statewide, 16 dead bird and 15 mosquito samples have tested positive, according to the California Department of Public Health. There have been no human cases in the state this year, according to state officials.

The district announced June 5 that the first mosquito sample this year was found in Sacramento County. The virus was first detected this year on May 17 when two dead birds found on Florin Road in south Sacramento tested positive.

In response to the recent findings, the district said it would continue to monitor West Nile virus activity through widespread mosquito trapping and testing and perform treatments in areas where positive mosquitoes have been found to decrease populations and protect public health.

Mild or moderate symptoms of the virus can include fever and fatigue. Severe symptoms in humans include neurological conditions such as encephalitis and meningitis. Severe illness from West Nile virus is rare, where only about one in 150 people are affected.

Avoid contracting the virus by draining standing water, avoiding being outdoors at dawn and dusk, dressing in long sleeves and pants when outside and making sure doors and windows are in good condition, the district said.

Those who see dead birds can report them to state health officials’ West Nile virus hotline at 877-968-2473.

Residents can direct mosquito problems to the district at 800-429-1022 or fightthebite.net.
