A bird found in Hillsborough late last month has tested positive for West Nile Virus, San Mateo County Mosquito & Vector Control District officials said.
The Cooper’s Hawk, which was picked up September 25 in Hillsborough, was found to have West Nile Virus chronic, meaning it is unlikely it became infected recently.
Traps have been set for mosquitoes in the area. So far, no mosquitoes tested from the vicinity of any of the previous West Nile Virus detections have tested positive for the virus.
Residents are advised to dump all standing water, and report freshly killed birds and squirrels to 1-877-WNV-BIRD.
