Results: The outbreak lasted 26 days. A total of 87 cases were reported, including 65 inpatients, 15 healthcare workers, 6 accompanies, and 1 pantryman. Twelve (60%) of 20 stool specimens were norovirus-positive by RT-PCR and 19 of 24 blood samples were norovirus-positive by Western blot. The outbreak was effectively controlled by isolating and treating the patients, extensive disinfection, and health education.
