It is described an acute gastroenteritis outbreak of probable hydric transmission in Ontinyent (Valencia). It was declared on the 31st of January, 1992 and affected 3541 people according to the declaration done by the sanitary services who attended the patients. The clinical situation was characterized by the presence of profuse and watery diarrhoea, nausea, vomiting, abdominal pain and fever or febricula.
A preliminary study of the cases has been done, the information being treated with the classical method of descriptive epidemiology and a later study of the transversal observation type by means of a telephone inquiry.
The results show that this outbreak affected approximately to a 30% of the population, and show the relation between consumption of water from the municipal water system and the outbreak, as well as the existence of a control population not affected for receiving a different water supply.
Once rejected the bacterial origin for the results of the copro-cultivation done the analysis of the clinical and epidemiological characteristics of the outbreak, show a total agreement with the criteria described by Kaplan to characterize acute gastroenteritis outbreaks because of Norwalk-like virus.
描述了在奥蒂涅特（巴伦西亚）发生的一起可能经水传播的急性肠胃炎暴发事件。该事件于1992年1月31日宣布，根据诊治患者的卫生服务部门的报告，有3541人受到影响。临床症状表现为大量水样腹泻、恶心、呕吐、腹痛以及发热或低热。
对病例进行了初步研究，采用经典的描述性流行病学方法处理信息，随后通过电话询问进行横向观察类型的研究。
结果显示，此次暴发影响了约30%的人口，表明市政供水系统的用水与此次暴发之间存在关联，以及存在因接受不同供水而未受影响的对照人群。
在粪便培养结果排除细菌起源后，对此次暴发的临床和流行病学特征进行分析，结果与卡普兰描述的诺如病毒样急性肠胃炎暴发的特征标准完全一致。
