In July 2000, an outbreak of gastroenteritis occurred at a tourist resort in the Gulf of Taranto in southern Italy. Illness in 344 people, 69 of whom were staff members, met the case definition. Norwalk-like virus (NLV) was found in 22 of 28 stool specimens tested. The source of illness was likely contaminated drinking water, as environmental inspection identified a breakdown in the resort water system and tap water samples were contaminated with fecal bacteria. Attack rates were increased (51.4%) in staff members involved in water sports. Relative risks were significant only for exposure to beach showers and consuming drinks with ice. Although Italy has no surveillance system for nonbacterial gastroenteritis, no outbreak caused by NLV has been described previously in the country.
2000年7月，意大利南部塔兰托湾的一个旅游胜地爆发了肠胃炎疫情。344人患病，其中69人为工作人员，均符合病例定义。在检测的28份粪便样本中，有22份检测出诺如病毒（NLV）。病因可能是饮用水受到污染，因为环境检查发现该旅游胜地的供水系统出现故障，自来水样本被粪便细菌污染。从事水上运动的工作人员的发病率有所上升（51.4%）。仅接触海滩淋浴设施和饮用加冰饮料的相对风险具有统计学意义。尽管意大利没有针对非细菌性肠胃炎的监测系统，但该国此前尚未描述过由诺如病毒引起的疫情。
