目的了解北京市手足口病重症病例流行特征,为进一步制定防控措施提供科学依据。方法对2009年北京市手足口病重症病例进行流行病学分析。结果 97.06%的手足口病重症患儿年龄<5岁,男性多于女性,散居儿童重症构成比高于其他人群,随着年龄上升,重症构成比有下降趋势。手足口病及早得到正确诊断,进展为重症的可能性越小。外地户籍患儿重症构成比为本地的2倍,EV71感染患儿重症构成比为CoxA16的4.90倍。结论应在外来人口聚集地等重点地区,针对小年龄组儿童家长,有针对性地开展宣传教育工作,以降低手足口病重症率。
Objective To understand the epidemiological characteristics of severe cases of hand-foot-mouth disease in Beijing and provide scientific evidence for further prevention and control measures. Methods The epidemiological analysis of severe cases of hand-foot-mouth disease in Beijing in 2009 was conducted. Results 97.06% of children with HFMD were less than 5 years old, more males than females and more likely to have severe diarrhea than those in other groups. As age increased, the proportion of severe cases decreased. Hand, foot and mouth disease diagnosed as soon as possible, the possibility of progress to severe disease is smaller. The proportion of children with permanent registered permanent residence in the field was twice that of the local residents, and the rate of serious illness in children with EV71 infection was 4.90 times that of CoxA16. Conclusion In key areas such as migrant population centers, targeted propaganda and education work should be targeted at parents of children of small age groups to reduce the incidence of hand-foot-mouth disease.
