Abstract
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 1-13 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. This article is protected by copyright. All rights reserved.
