A bird found in Foster City last month has tested positive for West Nile Virus, San Mateo County Mosquito & Vector Control District officials said Friday afternoon.
The Double-crested Cormorant, which was picked up on Aug. 28 in Foster City, was found to have contracted West Nile Virus.
In addition, a House Sparrow from Foster City and a Lesser Goldfinch from El Granada, which were submitted to the moquito & vector control district earlier this month, have been deemed West Nile Virus chronic.
The district will set traps to collect mosquitoes for testing around all three sites where the birds were found on Monday, provided it isn’t too windy.
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 eport freshly killed birds and squirrels to 1-877-WNV-BIRD.
