目的:通过了解某高校甲型H1N1流感病例的流行病学分布特征,为预防和控制流感在高校的蔓延提供依据。方法:以某高校2009年11月6日至2009年11月24日发病并确诊的74例甲型H1N1流感病例为研究对象,分析并比较病例的年龄、性别、学历层次、年级、专业、发病时间和临床症状。结果:74例甲型H1N1流感确诊病例均为学生,罹患率为1.63%,其中男性占94.6%,女性占5.4%;病例平均年龄为20.5岁±2.2岁;94.6%的病例为本科生;本科生罹患率(4.03%)显著高于研究生(0.14%);2006级见习期本科生罹患率(11.05%)显著高于其他年级学生;疫情的流行全距为19天,发病高峰为2009年11月13日至2009年11月18日;病例以发热、咳嗽、乏力、头疼等临床症状为主。结论:该高校甲型H1N1流感确诊病例多为22岁以下的男性学生。本研究提示加强见习学生的监测和管理、设立隔离宿舍、接种疫苗等有针对性的措施能够有效控制流感疫情在高校蔓延。
OBJECTIVE: To understand the epidemiological distribution of Influenza A (H1N1) in a university and provide a basis for preventing and controlling the spread of influenza in universities. Methods: A total of 74 influenza A (H1N1) isolates from a university from November 6, 2009 to November 24, 2009 were enrolled in this study. The age, sex, educational level, grade, specialty, onset Time and clinical symptoms. Results: The confirmed cases of influenza A (H1N1) in 74 cases were all students, the attack rate was 1.63%, of which 94.6% were male and 5.4% were female; the average age was 20.5 years ± 2.2 years; 94.6% were undergraduates; (4.03%) was significantly higher than that of the graduate students (0.14%). The prevalence of undergraduate students in 2006 (11.05%) was significantly higher than that of other grades. The prevalence of the epidemic was 19 days January 13 to November 18, 2009; cases were fever, cough, fatigue, headache and other clinical symptoms based. Conclusion: Most of the confirmed cases of Influenza A (H1N1) in this university are male students under 22 years of age. This study suggests that targeted measures such as strengthening the monitoring and management of trainee students, establishing dormitory isolation and vaccination can effectively control the spread of influenza in universities.
