某區域醫院精神科病房諾羅病毒之群聚感染

Outbreak of Norovirus Gastroenteritis at A Psychiatric Ward in A Regional Hospital

2006年6月底，某區域醫院精神科急性病房發生諾羅病毒 （Norovirus） 的群聚感染。52位人員發生腹瀉或發燒，其中50位是住院病人， 2位是工作人員。在送檢的32例糞便檢體中，17例經疾病管制局證實為諾羅病毒感染 （陽性率53.1%）。本文報告諾羅病毒 （Norovirus） 群聚感染的可能原因、調查和管制。在處理過程中，我們發現：（一）早期發現、立即通報、有效隔離和找出病原，是院內感染管制的最基本原則。（二）沒有症狀不等於沒有感染諾羅病毒，感染管制措施必須針對病房所有人員，才能有效控制疫情。（感控雜誌 2009; 19:362-9）。
