Abstract: Objective To estimate the epidemiological burden of norovirus (NoVs) acute gastroenteritis in Guangdong Province, so as to provide scientific basis for formulating or adjusting epidemic prevention and control strategies.Methods Using data from infectious diarrheal disease surveillance, diarrhea related surveillance, and investigation results in Guangdong Province from 2013 to 2017, the epidemiological burden of NoVs acute gastroenteritis was assessed by morbidity, disability adjusted life years ( DALYs), and the ratio of the number of cases reported by the internet to the number of actual incidence cases.Results The total number of cases of NoVs infectious gastroenteritis was 3.1027 million persons/year (2.535 9-4.037 6 million persons/year) in Guangdong Province from 2013 to 2017. The annual average number of medical visits was estimated to be 1.278 3 million persons/year (1.044 8-1.663 5 million persons/year). The annual average number of inpatients was estimated to be 383 persons/year (313-499 persons/year). The ratio of the number of cases reported by the internet to the number of actual incidence cases was 1∶1 203 (1∶860-1∶1 771). The average total annual burden was 19 200.55 DALYs(16 919.20-25 001.83 DALYs), and the per capita burden was 0.18 DALYs/thousand person-years (0.15-0.23 DALYs/thousand person-years).Conclusion The burden of acute gastroenteritis caused by NoVs was high in Guangdong Province. It is necessary to strengthen the management of prevention and control, as well as the publicity and education.
