目的通过一起手足口病暴发疫情的传播链分析,指导手足口病暴发疫情的预防控制。方法通过现场流行病学调查、结合实验室PCR病毒核酸检测对事件进行分析。结果共发病19例(死亡1例)。从病人肛拭子、咽拭子中检出肠道EV 71病毒。从传播链分析,19例患者经历了5代传播。结论生活中的密切接触、幼儿园同班接触、医源性感染是本起暴发疫情的主要传播因素;基层医生早诊断、早报告、早隔离、早转院正规治疗,防止医院内及社区、幼儿园内交叉感染,是预防控制暴发疫情、减少重症和死亡病例的最关键因素。
Objective To analyze the prevention and control of HFMD outbreak by analyzing the transmission chain of outbreak of HFMD. Methods According to the epidemiological investigation in the field and the laboratory PCR virus nucleic acid detection, the events were analyzed. The results of a total of 19 cases (1 death). The intestinal EV71 virus was detected from the patient’s anal swabs and throat swabs. From the transmission chain analysis, 19 patients underwent 5 generations of transmission. Conclusions Close contacts in life, contact with classmates in kindergarten and iatrogenic infection are the main transmission factors of the outbreak. Primary doctors early diagnosis, early report, early isolation, regular transfer to hospital early to prevent cross-in hospital and community, kindergarten Infection is the most crucial factor in the prevention and control of outbreaks and in the reduction of severe cases and deaths.
