We report on three nursing home outbreaks of gastroenteritis in Brisbane in 1999. The presence of Norwalk-like virus (NLV) genogroup 2 was demonstrated by reverse transcription polymerase chain reaction (RT-PCR) in all three outbreaks. Common findings of these investigations were rapid spread of the illness within the institutions and difficulties in identifying a common source. Nursing home populations are vulnerable and it is important for each institution to have infection control policies in place so outbreaks can be managed promptly. This includes the exclusion of ill staff for 48 to 72 hours after recovery from illness. Genogrouping of NLV by RT-PCR can take several days so control measures will generally have to be instituted before results become available.
我们报告了1999年布里斯班三起养老院肠胃炎疫情。通过逆转录聚合酶链反应（RT-PCR）在所有三起疫情中均检测到了诺如病毒样病毒（NLV）基因群2。这些调查的常见发现是疾病在机构内迅速传播，且难以确定共同来源。养老院人群较为脆弱，每个机构制定感染控制政策很重要，以便能及时管理疫情。这包括患病员工康复后48至72小时内不得上班。通过RT-PCR对NLV进行基因分型可能需要几天时间，因此通常必须在结果出来之前就采取控制措施。
