Abstract:

Objective To analyze the epidemiological characteristics and spatiotemporal clustering of hemorrhagic fever with renal syndrome (HFRS) in Jilin Province from 2011 to 2023 for a reference to develop prevention and control measures in areas with higher incidence of HFRS. Methods HFRS case data reported in Jilin Province from 2011 to 2023 were retrieved from the Chinese Disease Control and Prevention Information System. Descriptive epidemiological methods were used to analyze temporal, spatial, and population distribution. Global and local spatial autocorrelation analyses were performed using software ArcGIS. Results A total of 6 557 cases of HFRS, including 22 deaths, were reported in Jilin Province from 2011 to 2023, with an incidence rate of 1.87 per 100 000 population and the case fatality rate of 0.32%. The incidence rate was highest in 2014 (2.71/100 000), and the lowest in 2023 (0.66/100 000). HFRS cases were reported in each city (prefecture) of the Province. Meihekou City had the highest incidence (4.87/100 000). There were two epidemic peaks (March to June, and October to December), during which 2 660 (40.57%) and 1 918 cases (29.25%) were reported, respectively. The incidence rate was higher in males (2.87/100 000) than in females (0.82/100 000). The 50-59 age group had the highest incidence rate (2.76/100 000). Farmers constituted the majority of the cases (n=4 140, 63.14%). The spatial agglomeration analysis showed that the “high-high” agglomeration areas were mainly distributed in the eastern mountainous/semi-mountainous regions (Yanbian Korean Autonomous Prefecture, Baishan City, Tonghua City, Changbai Mountain Administrative Committee, Meihekou City) and western meadow-wetland areas (Baicheng City). Conclusion From 2011 to 2023, HFRS incidence in Jilin Province showed a declining trend, yet exhibited a distinct seasonality and spatial clustering. High-risk areas were concentrated in the eastern mountainous/semi-mountainous regions and western meadow-wetland ecosystems. Middle-aged/elderly, males and farmers were the most affected demographic, warranting prioritized interventions.
