DAVIS - A dead bird found near Davis has tested positive for the West Nile virus, according to officials from the Sacramento-Yolo Mosquito & Vector Control District.
The dead bird represents the first sign of the virus in Yolo County this year. In late January, a bird in Sacramento County tested positive for the virus.
No human cases of the disease have been reported this year, although health officials predict the Sacramento Valley region will be hit hard by the virus in coming months.
"We want to urge residents to start protecting themselves from mosquitoes and make sure they drain containers that can hold water to prevent mosquitoes from developing in their own yards," said David Brown, mosquito control district manager.
Symptoms of the virus include fever, headache and body aches. Less than 1 percent of people infected with West Nile virus will require hospitalization.
