病毒性胃肠炎病程短,是常见病。特征是恶心、呕吐、腹绞痛、腹泻,全身症状轻重不一,呈流行性或地方性发病。早年的研究主要是在流行病学方面。美国在50年代婴儿胃肠炎约20～50%分离出肠道病毒,如艾柯病毒、柯萨奇病毒与腺病毒,但对照者也有20%排出这些病毒。加以分离出的病毒多种多样,难于解释使这些资料。在对照研究中,“志愿者”口服有传染性的无菌粪便滤 Short duration of viral gastroenteritis is a common disease. Characteristics are nausea, vomiting, abdominal cramps, diarrhea, systemic symptoms of varying severity, was epidemic or endemic disease. Early studies mainly in the epidemiology. The United States in the 1950s about 20 to 50% of infant gastroenteritis isolated enterovirus viruses such as Echovirus, Coxsackie virus and adenovirus, but the control also 20% of these viruses. The virus to be isolated is diverse and difficult to interpret. In a controlled study, “volunteers” were orally infected with sterile excrement filters
