目的 了解江苏省常州市恙虫病历年发病水平、趋势及流行特征,为恙虫病防控提供依据。方法 在“中国疾病预防控制信息系统”中收集、整理常州市2012年1月1日－2021年12月31日恙虫病报告数据,采用描述性流行病学方法分析发病情况,描述恙虫病的地区、时间和人群分布特征。结果 2012－2021年,常州市共报告恙虫病病例149例,年报告发病率中位数为0.28/10万,2015年报告发病率最高,为0.74/10万,2012年最低,为0.04/10万。常州市各区（市）均有病例报告,前3位分别是武进区（60例,占40.27%）、新北区（34例,占22.82%）和溧阳市（20例,占13.42%）。疫情高峰为每年的10－11月,发病人群以农民、家务及待业人员为主,病例集中在45～69岁年龄组。结论 应加强恙虫病监测,对医务人员进行培训提高对恙虫病的诊断水平,开展高危人群健康教育以预防、控制恙虫病的发生与流行。
Objective To investigate the level, trend, and epidemiological characteristics of scrub typhus in Changzhou, China, and to provide a basis for prevention and control of the disease.Methods The reported data of scrub typhus in Changzhou from January 1, 2012 to December 31, 2021 were collected from the China Information System for Disease Control and Prevention. We analyzed the incidence of the disease and described the regional, temporal, and population distribution characteristics of scrub typhus using descriptive epidemiology method.Results From 2012 to 2021, a total of 149 cases were reported in Changzhou, with a median annual reported incidence rate of 0.28/100 000, with the highest reported incidence rate of 0.74/100 000 in 2015 and the lowest rate of 0.04/100 000 in 2012. Cases were reported in all districts of Changzhou, with the top three being Wujin district (60, 40.27%), Xinbei district (34, 22.82%), and Liyang city (20, 13.42%). Most cases were reported between October and November in farmers, household workers, and unemployed persons, and in persons aged 45-69 years.Conclusions Scrub typhus surveillance should be strengthened, medical personnel should be trained to improve the diagnosis of scrub typhus, and health education for high-risk populations should be carried out, in order to prevent and control the occurrence and prevalence of scrub typhus.
