Mosquitoes Collected in South San Francisco Negative for West Nile Virus

Today (Oct. 1st) the District laboratory collected mosquitoes in the area where a dead crow infected with West Nile virus was found earlier this week. These mosquitoes have all tested negative for West Nile virus.

While there doesn’t appear to be an elevated risk of WNV in our county at this time, residents should continue to report dead birds for testing and take precautions against mosquito bites when spending time outdoors at dusk and dawn.
