Dead Crows Signal Early West Nile Virus Activity

West Nile virus activity has been detected early in Southern California, with officials confirming the virus in two dead crows. These findings in Rolando and near Encanto and North Bay Terraces mark some of the earliest indications of the virus in the region this year.

While no human cases have been reported as of June 5, 2026, county health officials note that mosquitoes can transmit the virus to people after biting an infected bird. Symptoms in humans can range from none to mild ailments like headaches and fever, but severe illness or death is possible in rare instances.

Protecting oneself from mosquito bites is crucial, as these insects can inhabit various environments, including backyards and homes. While West Nile virus primarily affects birds, mosquitoes can also transmit other diseases if they bite infected individuals. Residents are advised to stay vigilant and take necessary preventative measures.
