Abstract:
Objective To analyze the epidemiological characteristics of norovirus infectious diarrhea in the active monitoring of foodborne diseases in Jiangsu Province from 2015 to 2020, so as to provide reference for the prevention and control of foodborne diseases caused by norovirus. Methods Norovirus positive diarrhea cases were collected from sentinel hospitals in 13 districts and cities of Jiangsu Province, and their epidemiological and clinical characteristics were analyzed. Results Atotal of 3 620 norovirus positive cases were detected and isolated from 61 489 samples. The main serotype was GII (71.97%), the onset season was winter and spring, and the onset age was 1-3 years old and 14-34 years old. There was no significant difference in norovirus positive rate between different sexes, and the main symptom was diarrhea (incidence rate was 92.10%), Meat and meat products (20.20%) were the main types of suspected exposed foods. Conclusion Norovirus infection has obvious seasonal characteristics, and the population is generally susceptible. It is high in children and young people, and meat food was the main suspicious exposure food. We should continue to improve the ability of active monitoring, identification, early warning and control of foodborne diseases, so as to reduce the occurrence of foodborne diseases.
