This report describes the results of an investigation on an outbreak of novel influenza A (H1N1) in an English language Institute in Seoul, Korea in May 2009.
In this outbreak, novel influenza A (H1N1) was confirmed in 22 of 91 trainees, trainers and staff members. The trainees and 2 staff members were isolated in an assigned facility and the rest were isolated in their homes after we discovered the first patient with novel influenza A (H1N1). After the isolation, the people in the assigned facility were educated to use N95 respirators and they received oseltamivir for prophylaxis.
The initial findings in this study suggest that the symptoms were mild and similar to those of seasonal influenza. The classmates and roommates of the infected patients were more likely to get infected with novel influenza A (H1N1) than the trainees who were not classmates or roommates of the patients (OR: 3.19, 95% CI=0.91 - 11.11 for classmates and OR: 40.0, 95% CI=7.4-215.7 for roommates).
The public health response seems successful in terms of preventing the spread of this virus into the local community.
本报告描述了2009年5月韩国首尔一所英语学院甲型H1N1流感疫情的调查结果。
在此次疫情中，91名学员、培训师和工作人员中有22人确诊感染甲型H1N1流感。在发现首例甲型H1N1流感患者后，学员和2名工作人员被隔离在指定场所，其余人员则在家中隔离。隔离后，对指定场所的人员进行了使用N95口罩的培训，并给予他们奥司他韦进行预防。
本研究的初步结果表明，症状较轻，与季节性流感相似。与非患者同学或室友的学员相比，感染患者的同学和室友感染甲型H1N1流感的可能性更大（同学的比值比：3.19，95%置信区间=0.91 - 11.11；室友的比值比：40.0，95%置信区间=7.4 - 215.7）。
就防止该病毒传播到当地社区而言，公共卫生应对措施似乎是成功的。
