Abstract: Objective To investigate the data on scrub typhus cases reported in Pinggu district of Beijing, China, in 2008-2018 and the epidemiological characteristics of scrub typhus, and to provide a scientific basis for the prevention and control of scrub typhus. Methods The data on scrub typhus cases reported in 2008-2018 were collected from the information system of Chinese Center for Disease Control and Prevention to analyze the epidemiological characteristics of scrub typhus. Results A total of 899 scrub typhus cases were reported in Pinggu district in 2008-2018, with a mean annual incidence rate of 18.70/100 000. The incidence rate of scrub typhus increased from 2008 to 2015 and then gradually decreased. Of all cases, 99.33% were reported in September to November of each year, suggesting that Pinggu district was an autumn-type epidemic area for this disease. This disease was mainly reported in patients aged 50-65 years, accounting for 52.73% of all cases. The disease was most prevalent among farmers, accounting for 77.20% of all cases. The highest incidence rate was found in Wangxinzhuang town and Daxingzhuang town. Conclusion There is a high incidence rate of scrub typhus in Pinggu district. Therefore, the key populations should be monitored in autumn and prevention and intervention measures should be adopted to reduce the development and prevalence of scrub typhus.

摘要： 目的 分析2008－2018年平谷区恙虫病病例报告数据，探讨其流行病学特征，为制定恙虫病防治措施提供理论依据。方法 收集中国疾病预防控制中心信息系统2008－2018年恙虫病病例报告资料，分析其流行特征。结果 2008－2018年平谷区共报告恙虫病病例899例，年平均发病率为18.70/10万。2008－2015年发病呈上升趋势，之后开始下降。发病高峰月份主要集中在每年的9－11月，占发病总数的99.33%，属秋季型疫区。发病年龄主要集中在50～65岁年龄组，占发病总数的52.73%。职业分布以农民为主，占发病总数的77.20%。以王辛庄镇和大兴庄镇发病率最高。结论平谷区恙虫病人群发病水平较高，应在秋季对重点人群的发病情况进行监测，并采取预防干预措施，降低恙虫病的发生和流行。
