The numbers of mosquitos most responsible for the transmission of West Nile virus to humans in Minnesota is among the highest ever recorded in the seven-county metro area, according to a recent update.

Mosquitoes that test positive for West Nile virus can be found all across the U.S. Is there a vaccine for West Nile virus available in the U.S. yet?

The mosquitoes were located in Arleta, South El Monte, Valley Glen, Van Nuys, Panorama City and Lake Balboa, according to the Greater Los Angeles County Vector Control District.

A Fort Collins resident is confirmed to be Larimer County’s first case of West Nile virus this year and the third human case reported in Colorado.
