摘要: 目的 分析云南省2006-2017年恙虫病的流行病学特征,为制定恙虫病的防治策略提供科学依据。方法 收集云南省2006-2017年的恙虫病疫情资料,采用SPSS 17.0软件及描述性流行病学方法对恙虫病的发病率、死亡率、病死率及疾病的地理、季节和人群分布进行分析。结果 12年间云南省每年均有恙虫病病例发生,累积发病27 838例,死亡11例,年发病率在0.65/10万~13.36/10万之间,总体呈上升趋势,病死率为0.04%。全省16个州(市)均有恙虫病病例发生,129个县(市)中有118个报道过恙虫病病例,其中保山和临沧市发病数最多,占总发病数的41.94%,迪庆藏族自治州发病数最低。恙虫病每年的发病高峰主要集中在高温多雨的8月,发病例数最多的为<5岁的农村儿童(占13.16%),职业分布以农民为主(占68.41%);男女性别比例为0.98:1。结论 云南省恙虫病高发,多发于8月,属夏秋型,以农民为主,<5岁的儿童居多,男女发病率差异不大。加强疫区居民的健康教育,提升基层医生恙虫病的诊断能力,增强野外作业时的防护和开展灭鼠灭螨为主的爱国卫生运动是防制该病的重要措施。

Abstract: Objective To analyze the epidemiological characteristics of scrub typhus in Yunnan province from 2006 to 2017, and provide the scientific evidence for the prevention and control, so that to reduce the incidence of scrub typhus. Methods To collect data of scrub typhus in Yunnan province from 2006 to 2017, and use descriptive epidemiology and SPSS 17.0 software for analysis of the temporal and spatial incidence and mortality of scrub typhus. Results Scrub typhus cases occurred every year in Yunnan during 2006-2017. A total of 27 838 cases were reported cumulatively, of whom 11 died. The annual incidence ranged from 0.65/100 000 to 13.36/100 000. The overall case fatality was 0.04%; the scrub typhus cases occurred in all 16 prefectures, the cases were reported from 118 of 129 counties (cities). Baoshan and Lincang cities had the most cases (41.94%), while Diqing prefecture had the lowest incidence. The cases mainly occurred in August, with a high temperature and rains. Most patients were children aged 0-5 years (13.16%) and farmers (68.41%). The ratio of male (49.53%) to female (50.47%) was 0.98:1. Conclusion The incidence of scrub typhus in Yunnan province is high, mostly in August, which belongs to summer and autumn type. Scrub typhus is prevalent in farmers and the children aged 0-5 years. There is no significant difference between males and females. Strengthening the health education in epidemic areas, improving the diagnostic ability, enhancing the protection in the field and carrying out the patriotic health campaign with rodent and chigger control are the important measures to prevent the scrub typhus.
