Abstract

Abstract

Objective To analyze the epidemiological characteristics and spatiotemporal distribution of influenza incidence in Fujian Province from 2010 to 2023, and provide a reference for scientific prevention and control. Methods The Joinpoint regression model was used to analyze the incidence trend, the epidemiological characteristics of influenza were described by using the descriptive analysis methods. ArcGIS 10.3 software was used to draw the incidence map and perform spatial auto-correlation analysis. The retrospective spatiotemporal scanning analysis was conducted using the SaTScan 10.1.2 software. Results From 2010 to 2023, a total of 343 909 cases of influenza was reported in Fujian Province, with an average annual incidence rate of 63.38 per 100 000 people. The incidence rate generally showed an upward trend, with an average annual percentage change (AAPC) of 38.56% (Z=6.86, P < 0.001). The disease mainly affected people aged 0-14 years old. There was both global and local autocorrelation in the incidence of influenza, with high-high clustering areas mainly located in some counties and districts along the southern coast of Zhangzhou and Xiamen. Spatial-temporal scan analysis has found that the main clustering areas were mainly in Zhangzhou and Xiamen, with clustering periods mostly occurring between November of each year and January of the next year, and occasionally occurring between June and August. Conclusions The incidence of influenza in Fujian has an upward trend from 2010 to 2023, and it is necessary to strengthen monitoring and prevention measures in key areas and populations, and more studies should be carried out to analyze the factors that affect the areas with high incidence of influenza and formulate corresponding prevention and control policies.
