West Nile virus activity is expected to surge in the Sacramento area as the summer progresses, authorities said. “As temperatures continue to rise, we expect mosquito populations and West Nile virus activity to increase throughout the summer,” said Gary Goodman, manager of the Sacramento-Yolo Mosquito and Vector Control District, in a Wednesday, June 24, news release.
Six mosquitoes and three dead birds have tested positive for the virus so far in 2026. “These positive mosquito samples and birds serve as an important reminder that residents should take steps now to reduce mosquito breeding around their homes and protect themselves from mosquito bites,” Goodman said. The mosquitoes and birds with the virus have mainly been found in the Carmichael and Tahoe Park areas, the agency said. The district will continue to monitor West Nile virus activity. This month, health officials in Placer County identified that county’s first West Nile virus-positive bird of 2026.
