Summary

  • Madison recorded Yolo County’s first West Nile-positive mosquito sample, making Yolo the fourth Northern California county to report virus activity.
  • Sacramento-Yolo Mosquito and Vector Control District said Yolo also has 2 positive dead birds, while neighboring Sacramento County has 24 positive mosquito samples and 38 positive dead birds.
  • The detection follows a recent human West Nile case in Sacramento County; the CDC says most infections cause no symptoms, but fewer than 1% turn severe and can lead to hospitalization or death.
  • The district said it will expand trapping, testing and ground treatments in positive areas, and will start weekly sterile male mosquito releases Tuesday across a 120-acre Rosemont zone to curb invasive Aedes aegypti.
