2007—2022年北京市恙虫病病例三间分布及疫源地现况

DISTRIBUTION AND EPIDEMIC FOCI OF TSUTSUGAMUSHI IN BEIJING FROM 2007 TO 2022

目的分析北京市2007—2022年恙虫病病例的流行病学特征。方法采用全局空间自相关分析、局部空间自相关分析空间分布特征,描述病例的空间聚集特征,分析北京恙虫病疫源地现况。结果2007—2022年北京市累计报告1307例恙虫病病例,发病率呈上升趋势。北京市恙虫病病例主要集中在9—11月。病例年龄范围10~91岁,年龄均数(56.58±13.31)岁,职业以农民为主,占74.45%(973/1307)。北京市病例分布范围呈扩大趋势。全局空间自相关分析显示,全局Moran′s I为0.208765(P<0.05),表明恙虫病在北京市呈现空间聚集特征,且存在空间正相关,病例主要聚集在平谷区,平谷区存在聚集性。结论北京市恙虫病发病呈上升趋势,应做好传播媒介消杀工作,并针对高危人群开展防病知识宣教,降低恙虫病发病率和疾病负担。

Objective To analyze the epidemiological and spatial distribution characteristics of tsutsugamushi cases in Beijing from 2007 to 2022.Methods The epidemiological characteristics of tsutsugamushi cases in Beijing from 2007 to 2022 were analyzed,and the spatial distribution characteristics of the cases were described by global spatial autocorrelation analysis and local spatial autocorrelation analysis.Additionally,the current situation of the epidemic focus of tsutsugamushi disease in Beijing was analyzed.Results A total of 1307 cases of tsutsugamushi were reported in Beijing from 2007 to 2022,with an increasing incidence.The cases of tsutsugamushi in Beijing were concentrated primarily from September to November.The age range of the cases was 10-91 years old,with a mean age of 56.58±13.31 years old.The majority of cases(74.45%,973/1307)were among farmers.The distribution of cases in Beijing exhibited an expanding trend.The global spatial autocorrelation analysis revealed that the global Moran′s I was 0.208765(P<0.05),indicating that tsutsugamushi disease exhibited spatial clustering characteristics and spatial positive correlation in Beijing.The cases were primarily concentrated in Pinggu District,with a secondary concentration in Pinggu District.Conclusion The incidence of tsutsugamushi disease is on the rise in Beijing.It is imperative to implement effective vector elimination strategies and disseminate disease prevention knowledge to high-risk groups in order to reduce the incidence and burden of tsutsugamushi disease.
