Abstract:
Objective:Analyzing the epidemic trends and spatio-temporal distribution characteristics of condyloma acuminatum in China from 2018 to 2023.Methods:Data of condyloma acuminatum cases and incidence rate including 31 provinces (autonomous regions and municipalities) from 2018 to 2023 were collected through the National Notifiable Infectious Disease Reporting System of China Information System for Disease Control and Prevention. Incidence trend analysis was conducted using Joinpoint 4.9.1 software, and spatial autocorrelation analysis using ArcGIS 10.5 software. Spatio-temporal scanning analysis was carried out with SaTScan 10.1.2 software.Results:The incidence rate of condyloma acuminatum declined from 7.26 per 100 000 in 2018 to 7.19 per 100 000 in 2023. The average annual percent change was -0.26%, which was no statistically significant downward trend ( t=-0.26, P=0.806). A significant positive global spatial autocorrelation was observed in the county-level incidence rate across the country, with the global Moran's I ranging from 0.55 to 0.60 (all P<0.001); the Getis-Ord General test statistic Z( G) was all >1.96, indicating a high-value clustering pattern in the reported incidence rate of condyloma acuminatum. The local spatial autocorrelation analysis detected 256, 244, 246, 284, 308, and 315 hotspots each year, which were mainly located in the provinces of Zhejiang, Fujian, Guangdong, Guizhou, Yunnan and Chongqing. Spatio-temporal scanning analyses identified 76 statistically significant spatiotemporal clusters covering 25 provinces (autonomous regions and municipalities). Conclusions:From 2018 to 2023, the reported incidence rate of condyloma acuminata in China exhibited a mild decline. The distribution of hotspot areas and spatiotemporal clusters was largely consistent, primarily in the southeastern coastal and southwestern regions.
