Abstract:
This study analyzed the epidemic characteristics and spatial and temporal clustering of leptospirosis in Wenzhou from 2014 to 2023,to provide a scientific basis for prevention and control.Data for leptospirosis cases reported in Wenzhou from 2014 to 2023 were collected.Descriptive epidemiological approaches were used to analyze the cases'prevalence character-istics.Spatial autocorrelation analysis was performed in ArcGIS 10.2 software,and spatiotemporal clusters were scanned with SaTScan 10.1 software.From 2014 to 2023,189 leptospirosis cases were reported in Wenzhou,and the average annual inci-dence rate was 0.23/100 000.Relatively fewer cases occurred in 2014-2018,whereas significantly more cases occurred after 2019,and the largest number of reported cases was reported in 2021(62 cases).The peak incidence was from August to Octo-ber,accounting for 88.36％of the total incidence.The cases were mainly in males,and the sex ratio was 5.30∶1 male:female.Moreover,the cases were mainly in people in their 60s,accounting for 59.26％of total cases,and in people who were farmers,accounting for 72.49％of total cases.Global spatial autocorrelation analysis indicated that cases were randomly distributed from 2014 to 2018,and the incidence showed spatial clustering from 2019 to 2023(Moran's I＞0,P＜0.05).Local spatial autocor-relation and spatiotemporal scanning analysis revealed that leptospirosis cases were concentrated primarily in northern hilly areas of Yongjia County and other inland areas rich in vegetation from 2019 to 2023.In the past 5 years,the number of lepto-spirosis cases in Wenzhou increased,and the incidence of leptospirosis showed clear seasonal and spatial clustering.Cases were mainly in middle-aged and older farmers.Recommendations in-clude expanding the monitoring scope of leptospirosis,and per-forming prevention and control measures such as health education for key groups in key areas before the high-incidence season.
