摘　　要：目的 分析河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2017-2021年河南省百日咳报告病例,采用描述流行病学方法分析发病特征。结果 共报告百日咳病例1 198例,年均报告发病率为0.25/10万,各年发病率分别为0.13/10万、0.32/10万、0.55/10万、0.09/10万、0.16/10万。病例报告主要集中于6-9月,占48.33%。各省辖市均有病例报告,居前三位为鹤壁市(294例,3.64/10万)、商丘市(273例,0.89/10万)和三门峡市(55例,0.50/10万),各地报告发病率存在差异(χ^(2)=5 303.552,P<0.001)。0岁组报告发病率最高(8.15/10万),报告病例5岁以下占81.30%,其中≤2月龄占10.68%,≥15岁病例占0.08%(均为成人)。病例以散居儿童为主,占75.29%。结论 2017-2021年河南省百日咳病例以5岁以下、散居儿童为主,≤2月龄婴儿占比较高,病例报告多集中于6-9月,具有夏秋季高发的特点。建议加强百日咳监测,探讨低龄儿童百日咳免疫策略,优化百日咳疫苗免疫程序。Objective To analyse the epidemiological characteristics of pertussis cases in Henan province.Methods The reported cases of pertussis in Henan province from 2017 to 2021 were collected through China Disease Control and Prevention Information System,and the characteristics of pertussis were analyzed by descriptive epidemiology.Results There were 1 198cases of pertussis reported in Henan province from 2017 to 2021,with the annual reported incidence of 0.25/100 000,and the annual reported incidence was 0.13/100 000,0.32/100 000,0.55/100 000,0.09/100 000 and 0.16/100 000,respectively.The cases were mainly reported from June to September,accounting for 48.33%.Every prefecture-level city had cases reported,and the top three cities included Hebi city (294 cases,3.64/100 000),Shangqiu city (273 cases,0.89/100 000) and Sanmenxia city(55 cases,0.50/100 000);there were differences in the reported incidence among different cities (χ^(2)=5 303.552,P<0.001).The 0year-old group reported the highest incidence (8.15/100 000);81.30%of the reported cases were under 5 years old,10.68%were less than 2 months old,and 0.08%were≥15 years old (all of them were adults).The majority of cases were scatteredliving children,accounting for 75.29%.Conclusions From 2017 to 2021,the majority of pertussis cases in Henan province were children under 5 years old and scattered-living,and children≤2 months old accounted for a relatively high proportion.The cases were mostly reported from June to September,with an obviously high incidence in summer and autumn.It is suggested to strengthen pertussis surveillance,explore the immunization strategy of young children and optimize the immunization procedure of pertussis vaccine.
