摘要


民國93年2月底,某家區域醫院的呼吸照護病房發生類諾瓦克病毒(Norwalk-like virus、 Norovirus)所引起的腸胃炎集體感染,35位人員發生腹瀉或發燒,其中26位爲住院患者、8位爲工作人員、1位爲工作人員家屬。針對呼吸照護病房所有人員,採集糞便檢體,利用反轉錄酶-聚合酵素鏈鎖反應,檢查是否有類諾瓦克病毒。在全部38位住院患者中有35位感染類諾瓦克病毒,感染率高達92.1%,腹瀉、發燒症狀持續時間爲2天,沒有留下後遺症。而41位工作人員當中,有8位感染類諾瓦克病毒,嘔吐及腹瀉出現時間爲1到2天,感染率19.5%,另外有1位工作人員的家屬也感染類諾瓦克病毒。在35位感染類諾瓦克病毒的住院患者當中,有12位沒有出現症狀,佔了34.3%,而8位感染的工作人員當中,有2位沒有症狀,佔了25.0%。在群突發感染的處理過程當中,沒症狀的人員不等於沒有感染類諾瓦克病毒,感染管制措施必須針對病房所有人員,才能有效控制疫情。
