摘要:
目的 了解台州市2011―2021年恙虫病的流行特征与时空聚集性,为台州市恙虫病的预防与控制提供科学依据。 方法 从台州市疾病预防控制中心获得台州市2011―2021年恙虫病病例的资料,使用SaTScan 9.6软件进行时空聚集性分析和结果可视化。 结果 2011―2021年台州市共报告恙虫病病例225例,年均发病率为0.32/10万。以50~69岁人群为主,占65.8%(148/225)。职业分布以农民为主,占87.1%(196/225)。仙居县位于台州市西北部,以低山地貌为主,为该病高发地区,报告病例数占比53.3%(120/225),该地区是扫描出的一类聚集区;二类聚集区为天台县、三门县和临海市交界地区。 结论 台州市2011―2021年恙虫病发病率呈上升趋势,易感人群主要为山区≥50岁中老年农民,应加强对易感人群的宣传教育工作,在野外劳作时做好个人防护,控制恙虫病的发生和流行。 Abstract:Objective To analyze the epidemiological characteristics and spatial-temporal clusters of scrub typhus in Taizhou during 2011-2021, and provide scientific evidence on prevention and control for scrub typhus. Methods Information on scrub typhus cases in Taizhou from 2011 to 2021 was obtained from Taizhou Center for Disease Control and Prevention. Spatial-temporal clusters analysis and result visualization were performed using SaTScan 9.6 software. Results A total of 225 cases of scrub typhus were reported from 2011 to 2021 in Taizhou, with an average annual incidence of 0.32/100 000. The primary affected demographic was individuals aged 50-69 years, which constituted 65.78% (148/225) of the cases. Farmer was the primary occupation and accounted for 87.11% (196/225). Xianju County is located in the northwest of Taizhou City, mainly with low mountainous landforms, which emerged as a high-incidence area with 53.33% (120/225) reported cases. This area is also the first cluster area. And the second cluster area was the junction area of Tiantai County, Sanmen County and Linhai City. Conclusions The incidence of scrub typhus in Taizhou from 2011 to 2021 was showing an upward trend. The susceptible people are mainly middle-aged and elderly farmers in mountainous areas. It is necessary to strengthen the publicity and education for these people, and personal protection should be done when working in the field to control the occurrence and prevalence of scrub typhus. -
