Norwalk-like viruses (NLVs) are a major cause of sporadic gastroenteritis in the community and of large outbreaks of gastroenteritis in hospitals and other institutions. In January 2001, 38 staff and 20 patients on an acute elderly care ward became ill in an outbreak of gastrointestinal infection. Using reverse transcription polymerase chain reaction (RT-PCR) the causative agent was identified as NLV. No link was found between particular foods eaten and illness. At various times in the course of the outbreak a number of wards were implicated, but in hindsight the outbreak was confined to one ward. A prompt and rigorous response was successful in containing the spread of NLV infection to just one ward and stopping it in a few days.
诺如病毒（NLVs）是社区散发性肠胃炎以及医院和其他机构中大规模肠胃炎暴发的主要病因。2001年1月，某急性老年护理病房的38名工作人员和20名患者在一次胃肠道感染暴发中患病。通过逆转录聚合酶链反应（RT-PCR），确定病原体为诺如病毒。未发现食用特定食物与疾病之间存在关联。在暴发过程中的不同时间，多个病房受到牵连，但事后发现暴发仅限于一个病房。迅速而严格的应对措施成功地将诺如病毒感染的传播控制在仅一个病房，并在几天内阻止了疫情。
