The risk of West Nile virus in Sacramento and Yolo counties remains high as more mosquitoes test positive for the virus, officials say.

The Sacramento-Yolo Mosquito and Vector Control District received confirmation Wednesday that 15 new mosquito samples tested positive for the virus throughout the two counties.

“Virus activity continues to be intense,” Gary Goodman, district manager, said in a written statement. “While activity is not uncommon during the summer, we are seeing an increase in the overall abundance of mosquitoes collected in our traps.

Specific areas of concern, where much of the West Nile virus activity is concentrated, include North Highlands, Carmichael, Elk Grove and Fair Oaks. Goodman said the district is closely monitoring those areas to determine the best plan of action. More aerial spraying might be conducted next week, he said. Additional laboratory results will be available Friday that will help determine whether further aerial treatments are needed.

In Yolo County, officials said, West Nile virus activity is on the rise in Woodland and parts of Davis.

So far this year, 188 mosquito samples and 205 dead birds have tested positive for West Nile virus in Sacramento County, and 30 mosquito samples and 12 dead birds have tested positive for the virus in Yolo County.
