美国Norwalk样病毒(NLVs)导致的散发病例估计每年达2300万,其中5万例住院,死亡300例。NLVs可通过被粪便污染的食物和水传播,也可通过人与人直接接触或感染人的飞沫传播。NLVs相关胃肠疾病的暴发是军营中的常事。2002年5月13日至19日,阿富汗野战医院有29名英国士兵经短暂潜伏期后急性发病,出现呕吐、腹泻和发热症状。本文摘要报道了此次调查情况,并强调提高NLVs诊断能力十分重要。
An estimated 23 million cases of sporadic cases are caused by the United States Norwalk-like viruses (NLVs), of which 50,000 are hospitalized and 300 are fatal. NLVs can be transmitted through food and water contaminated with faeces, as well as through human-to-human droplets or human droplets. Outbreaks of NLVs related gastrointestinal diseases are commonplace in military camps. From 13 to 19 May 2002, 29 British soldiers at the Field Hospital of Afghanistan were briefly attacked after a short incubation period, with symptoms of vomiting, diarrhea and fever. This summary of the article reports on the survey and emphasizes the importance of improving the diagnostic ability of NLVs.
