Objective:
To investigate and analyze a case of acute norovirus gastroenteritis outbreak in a hospital.
Methods:
Data were collected through the on-the-spot investigation and faecal specimens were tested by polymerase chain reaction-reverse transcription (RT-PCR). Serum specimens were tested by Western blot.
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.
Conclusion:
The gastroenteritis outbreak was caused by norovirus with unkown infection source.
