Two outbreaks of epidemic vomiting are described. One affected 107 students and staff at a college of education out of a total of 398 persons. The other affected 172 pupils and staff out of 357 at a secondary school. Evidence is presented that in both cases infection was acquired in the dining hall of the institution concerned but no specific item of food was found as a likely cause. The literature is reviewed. Possible mechanisms of spread are suggested.
本文描述了两起流行性呕吐疫情。一起疫情发生在一所教育学院,在总共398人中,有107名学生和教职工受到影响。另一起疫情发生在一所中学,在357人中,有172名学生和教职工受到影响。有证据表明,在这两起疫情中,感染均在相关机构的食堂感染,但未发现可能导致感染的特定食物。本文对相关文献进行了综述,并提出了可能的传播机制。
