2011年山东省济南市历城区托幼机构手足口病聚集性疫情分析

Epidemiological characteristics of clustering cases of hand, foot and mouth disease in child care settings in Licheng, Jinan, 2011

  • 摘要: 目的 探讨济南市历城区托幼机构手足口病聚集性疫情的流行病学特征和影响因素,为疫情控制提供参考。 方法 应用描述流行病学方法, 对济南市历城区2011年托幼机构手足口病聚集性疫情进行分析。 结果 2011年1-12月,济南市历城区共发生45起托幼机构手足口病聚集性疫情, 发病266例, 平均罹患率为2.40%。病例均为轻型。发病以3~4岁儿童为主, 占发病总数的76.32%。发病高峰4-7月。采样24起,采集粪便标本52份,肠道病毒71型(EV71)阳性29份(55.77%),柯萨奇病毒A组16型(Cox A16)阳性12份(23.08%),其他肠道病毒(PE)感染6份(11.54%)。首例病例发病时间-就诊时间间隔平均1 d。疫情平均持续7 d。 结论 疫情持续时间与托幼机构停课及时性之间有统计学相关性(r=0.494,P=0.001)。不同病原学型别引起的疫情持续时间差异无统计学意义(F=0.799,P=0.466)。加强托幼机构手足口病监测,及早识别首例病例,严格隔离传染源,把好消毒关、及时采取停课措施,是控制疫情的关键。

     

    Abstract: Objective To learn about the epidemiological characteristics of clustering cases of hand, foot and mouth disease (HFMD) in child care settings in Licheng district and provide scientific evidence for prevention and control of the disease. Methods Descriptive epidemiological analysis was conducted on the incidence data of clustering cases of HFMD in child care settings in Licheng in 2011. Results Forty five epidemics of HFMD occurred from January to December 2011,involving 266 cases. The average attack rate was 2.40%. All cases were mild. The cases in age group 3-4 years accounted for 76.32% of the total cases. The incidence peak was during April-July. Totally 52 stool specimens were collected. EV71 were detected in 29 specimens (55.77%), Cox A16 were detected in 12 specimens (23.08%) and other enteroviruses were detected in 6 specimens (11.54%). The average interval between onset and treatment of the first case was 1 day and the average duration of the epidemics was 7 days. Conclusion There was statistical correlation between the epidemic duration and the timeliness of school closure (r=0.494,P=0.001). There were no significance differences on the durations of epidemics caused by different pathogens (F=0.799,P=0.466). It is essential to strengthen the surveillance of HFMD for the early detection of the first case, isolate the infected person, conduct disinfection and declare school closure to control the spread of the disease.
