A norovirus outbreak sickened more than 30 people working in the pediatric intensive-care unit of Doernbecher Children's Hospital in Portland, according to an article on the Oregon Live website.
Most of those infected were nurses, along with a few doctors and other staff.
OHSU ordered a deep cleaning of restrooms, lounges and clinical areas with norovirus-killing agents every two to four hours. Food and drink were banned from common areas in the intensive-care unit, and staff were asked not to share food.
To encourage employees not to bring potentially contaminated food or snacks to work, they were given vouchers to eat in a campus cafeteria.
