Epidemiological trends and spatiotemporal clustering of hepatitis E in Fujian Province,2014-2023
Objective To analyze the epidemic trend and spatiotemporal clustering of hepatitis E in Fujian Province.Methods The reported incidence data of hepatitis E in Fujian Province from 2014 to 2023 were collected through the China information system for disease control and prevention.The change trend of the reported incidence rate was described using the Joinpoint 5.1.0.0 model.Spatiotemporal scanning analysis was performed using SaTScan V9.5 software.Results A total of 8108 cases of hepatitis E were reported in Fujian Province during 2014-2023,for an average annual reported incidence of 2.05 per 100 000.there was a downward trend(APC=-7.41％,95％CI:-22.09％-2.25％,P=0.009),while from 2020 to 2023,there was an upward trend(APC=15.95％,.95％CI:0.94％-42.43％,P=0.034).The main epidemic season was winter and spring.The reported incidence rate of hepatitis E in men was higher than that in women(x2=583.42,P＜0.001),and the reported incidence rate showed an over all upward trend with the increase of age(x2=4 607.00,P＜0.001).The spatiotemporal scan analysis has revealed seven types of spatial clustering areas for hepatitis E.Conclusions From 2014 to 2023,the reported incidence rate of hepatitis E in Fujian Province showed a downward trend and then an upward trend middle aged and elderly men were the main affected population,and the incidence was spatiotemporal clustering.It was necessary to strengthen the monitoring of hepatitis E in high-risk groups and hot spots.
