摘　　要：目的 分析2015—2020年达州市手足口病和病原学流行现状,为达州市手足口病防控提供科学依据。方法 对中国疾病预防控制信息系统中2015—2020年现住址为达州市的手足口病例信息和达州市疾控中心实验室病原学资料进行统计分析,率的比较采用χ^(2)检验,检验水准α=0.05。结果 2015—2020年达州市共报告手足口病例17 108例,年平均发病率为50.49/10万,偶数年发病率高于奇数年,各县(市、区)每月均有病例报告,发病呈现5-7月和10-11月两个高峰;男女比为1.49∶1,男性发病高于女性,5岁以下儿童占96.76%,以散居儿童为主,幼托儿童次之;共检测1 728份标本,阳性率为69.97%,EV 71构成比降至1%以下,其他肠道病毒构成比升高。结论 达州市2015—2020年手足口病处于低流行状态,呈现明显季节性和周期性,防控重点在两个高峰时间和5岁以下儿童,优势毒株为其他肠道病毒,需进一步强化社区健康教育工作,并尽快开展其他肠道病毒分型工作,明确当前流行毒株。Objective To analyze the epidemiological characteristics of hand-foot-mouth disease(HFMD) in Dazhou City from 2015 to 2020,and to provide scientific basis for the prevention and control of HFMD. Methods The information of HFMD cases of Dazhou City and the laboratory pathogenic data of Dazhou Center for Disease Prevention and Control from 2015 to 2020 in China Information System for Disease Prevention and Control were statistically analyzed. Chi-square test was used for comparision, the test level was α =0.05. Results A total of 17 108 HFMD cases were reported in Dazhou City from 2015 to 2020,with an average annual incidence rate of 50.49/10~5. The incidence rate of even-numbered years was higher than that of odd-numbered years. Each county/city/district reported cases every month. The incidence showed two peaks, May to July and October to November. The ratio of male to female was 1.49∶1. The incidence of males was higher than that of females. Children under 5 years old accounted for 96.76%. And cases were mainly scattered children, followed by preschool children. A total of 1 728 samples were tested, and the positive rate was 69.97%. The composition ratio of EV 71 decreased to less than 1%, and the composition ratio of other enteroviruses increased. Conclusions Hand-foot-mouth disease in Dazhou City was in a low epidemic state from 2015 to 2020, showing an obvious seasonality and periodicity. The prevention and control measures should focus on the two peaks and children under5 years old. The dominant strains were other enteroviruses. Community health education should be further strengthened,and the typing of other enteroviruses should be carried out as soon as possible to clarify the current epidemic strains.
