An explosion of coronavirus infections at California's San Quentin State Prison, the state's oldest, has public health officials there worried about its impact on prisoners, staff and the wider hospital system in the San Francisco Bay Area.
"Shocking, heartbreaking are certainly the words I would use to describe it," said David Sears, a physician and professor of medicine at the University of California, San Francisco. He recently toured San Quentin and warned officials about just such an outbreak.
