To analyze the epidemiological patterns and transmission characteristics of norovirus in China, providing new scientific evidence for prevention and control strategies in the post-COVID-19 era.
Epidemiological data on norovirus outbreaks in China over the past two decades were collected and analyzed via a review of relevant literature from four major databases (CNKI, Wanfang, Web of Science, and PubMed).
The epidemiological characteristics of norovirus outbreaks in China exhibited dynamic changes, highly correlated with the alternation of globally dominant strains. High outbreak frequency was associated with specific geographical regions (East China and South China regions, 63.27%), transmission routes (foodborne transmission, 29.15%), outbreak settings (schools, 72.57%), and viral genogroups (GII, 76.07%). Cross-analysis revealed that school outbreaks predominantly involved person-to-person and waterborne transmission, while the GII genotype spread chiefly through interpersonal contact, foodborne contamination, and aerosol dispersion.
Norovirus epidemics in China demonstrate distinct spatiotemporal clustering and diverse transmission pathways, necessitating targeted reinforcement of prevention and control measures to address these multifaceted challenges.
