BACKGROUND
National media reported a febrile illness among dormitory residents of a boys' religious school. We investigated the outbreak to identify cause.
METHODS
Individuals with fever (>100°F) and cough or sore throat between 1 and 13 August 2011 were influenza-like-illness (ILI) case-patients. We collected histories and specimens from hospitalized case-patients and visited campus to explore environmental context.
RESULTS
All 28 case-patients were dormitory residents including 27 hospitalizations. Accommodation space per resident was <0.8 square metres. Nasal and oropharyngeal swabs from 22 case-patients were positive for influenza B virus using real-time reverse transcription polymerase chain reaction (rRT-PCR).
CONCLUSIONS
Overcrowding likely facilitated transmission leading to this dormitory outbreak.
背景
国家媒体报道了一所男子宗教学校宿舍居民中出现的发热疾病。我们对此次疫情进行了调查以确定病因。
方法
2011年8月1日至13日期间出现发热（>100°F）且伴有咳嗽或喉咙痛的个体为流感样疾病（ILI）病例患者。我们收集了住院病例患者的病史和标本，并走访了校园以探究环境情况。
结果
所有28例病例患者均为宿舍居民，其中27人住院。每名居民的住宿空间小于0.8平方米。使用实时逆转录聚合酶链反应（rRT-PCR）对22例病例患者的鼻拭子和口咽拭子检测发现，乙型流感病毒呈阳性。
结论
过度拥挤可能促使了此次宿舍疫情的传播。
