West Nile Virus is back in Southern California. For the first time this year, a dead crow has tested positive in Los Angeles County.

The bird was found in West Covina near San Bernardino and Azusa Canyon roads.

Health officials are again urging residents to protect themselves from mosquitoes. Mosquito bites generally spread the disease.
