San Quentin State Prison officials are taking precautions today after a rash of possible norovirus cases broke out among inmates and employees.

Rudy Luna, administrative assistant to the warden, says last week prison officials last week noticed a larger-than-normal number of staff and prisoners with flu-like symptoms.

Luna says since Wednesday, prison officials have restricted the movement of sick inmates, instituted rigorous cleaning measures and placed hand sanitizers throughout the facility.
