Objective The purpose of this study was to analyze the prevalence of varicella in Yichang City,Hubei Province from 2018 to 2019 through the China Disease Control and Prevention Information System and the Yichang City Health Management Big Data Analysis Center(Big Data System),comparing and evaluating their respective characteristics and advantages,and providing a reference for guiding disease surveillance in the region.Methods Utilizing the China Disease Prevention and Control Information System and the Big Data System,data on varicella cases in Yichang City,Hubei Province from 2018 to 2019 were collected,and a comparative analysis was conducted using descriptive epidemiological methods.Results From 2018 to 2019,The China Disease Control and Prevention Information System reported 1 632 cases of varicella,while the big data system reported 1 937 cases.The distribution of varicella cases in the two systems showed similar characteristics:a higher proportion of cases in males than females;a bimodal distribution with peaks in the second and fourth quarters and a trough during school breaks;the age group 10-＜15 years was most affected;and varying varicella incidence rates across different regions,ranging from 52.4 to 92.8 per 100 000.Differences in the age and diagnosis date distributions of cases were observed in different regions,with a more balanced distribution of cases in areas with smaller populations.Conclusions The similarities in the epidemiological characteristics of varicella cases in urban areas of Yichang City,as indicated by the Big Data System and the China Disease Prevention and Control Information System,suggest that the Big Data System serves as a valuable complementary data source for the latter,enhancing the completeness of varicella reporting.
