目的进一步核实疫情,寻找导致手足口病暴发的危险因素,采取控制措施。方法应用描述流行病学方法分析病例的时间分布,提出初步病因假设,进行病例对照研究,验证假设。结果发病前1周与手足口病患者接触是危险因素(P<0.05),发病儿童存在明显的家庭聚集现象与玩伴亲戚病例接触史现象。社区病例接触而非幼儿园接触是主要传播方式。村内防控措施不严。结论本次手足口病疫情是以在社区与患者间的密切接触传播为主,并非在幼儿园,患儿隔离期未满即与其他儿童接触是造成疾病蔓延的主要原因。
Objective To further verify the epidemic, find out the risk factors of HFMD outbreak and take control measures. Methods The epidemiological method was used to analyze the time distribution of cases, the initial etiological hypothesis was put forward, the case-control study was conducted to verify the hypothesis. Results One week before the onset of HFMD contact with HFMD patients was a risk factor (P <0.05). There was a significant incidence of familial aggregation and contact history with relatives of playmates in the onset children. Community case contact rather than nursery contact is the main mode of transmission. Village lax prevention and control measures. Conclusion The outbreak of hand-foot-mouth disease is based on the close contact between the community and patients. It is not in kindergarten. The contact with other children during the isolation period is the main reason causing the spread of the disease.
