2009-2018年云南省百日咳报告病例流行病学特征

Epidemiological characteristics of reported pertussis cases in Yunnan province,2009-2018

目的了解2009-2018年云南省百日咳流行病学特征。方法通过中国疾病预防控制信息系统收集2009-2018年云南省报告的百日咳病例,进行描述性流行病学分析。结果2009-2018年云南省共报告百日咳429例,年均发病率为0.09/10万,各年发病率在0.04/10万(2014年)-0.19/10万(2018年)之间。在所有病例中,临床诊断、确诊病例分别占89.74%、10.26%;昭通市、西双版纳州、文山州和红河州病例占71.33%;发病高峰为5月和8月,5-8月病例占46.15%;<1岁、≤5岁病例分别占59.91%、91.84%;省外医院诊断报告病例占30.77%。结论2009-2018年云南省百日咳发病呈上升趋势和低水平流行;需建立规范的百日咳监测体系,提升实验室检测与医务人员诊断报告能力。

Objective To determine epidemiological characteristics of pertussis during 2009-2018 in Yunnan province.Methods We obtained data on pertussis cases reported from Yunnan to the China Information System for Disease Control and Prevention during 2009-2019 for a descriptive epidemiological analysis.Results A total of 429 pertussis cases were reported during 2009-2018,for an average annual incidence of 0.09 cases per 100000 population.The incidence by year ranged 0.04 per 100000 in 2014 to 0.19 per 100000 in 2018.Clinically confirmed cases and laboratory confirmed cases accounted for 89.74%and 10.26%of all cases,respectively;71.33%of cases occurred in Zhaotong,Xishuangbanna,Wenshan,and Honghe prefectures.Incidence rates peaked May through August,with46.15%of cases occurring between May and August;59.91%of cases were among infants<1 year old,and 91.84%were among children≤5 years old;30.77%of cases had been reported by hospitals in other provinces.Conclusion The incidence of pertussis increased from 2009 to 2018 in Yunnan.We should standardize pertussis surveillance and improve laboratory test capacity,clinical diagnosis and case reporting.
