DISTRIBUTION AND EPIDEMIC FOCI OF TSUTSUGAMUSHI IN BEIJING FROM 2007 TO 2022
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 1 307 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.
