[An acute norovirus gastroenteritis outbreak in a hospital].

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.
