Objective To analyze the epidemiological characteristics of Norovirus virus outbreaks in travel groups and provide reference for preventing the occurrence of similar events. Methods The data of outbreaks of diarrhea reported from February to April in 2012 were collected and analyzed by descriptive epidemiological method. Results The total incidence of acute diarrhea among the six tour groups was 18.2% (43/236), with a common meal history (Restaurant A in some city of Fujian Province). A total of 18 samples collected from 4 tour groups and 3 staff from restaurant A detected Norovirus. Conclusion This incident may be caused by food or water-borne food-borne diseases caused by norovirus infection in restaurant A of a certain city. A foodborne disease monitoring platform for tourists should be established to improve the coordination mechanism of foodborne disease treatment.
