Respiratory viruses and histological appearances of the lung were studied prospectively in an unselected series of 104 children who died between 1 week and 2 years of age. Thirty-one of the cases were cot deaths. Seven of these showed evidence of active virus infection in the lower respiratory tract. Similar evidence was found in two children who died from known causes and did not have a severe respiratory illness terminally. Although in some cases of cot death respiratory viruses may be responsible for a severe and rapidly overwhelming illness, the present results are compatible with an alternative hypothesis-namely, that minor respiratory illness may trigger sudden apnoea.
对104名1周龄至2岁死亡儿童的未筛选队列进行了前瞻性研究，观察呼吸道病毒和肺部组织学表现。其中31例为婴儿猝死综合征。其中7例显示下呼吸道有活跃病毒感染迹象。在另外两名已知病因死亡且临终时无严重呼吸道疾病的儿童中也发现了类似证据。虽然在某些婴儿猝死综合征病例中，呼吸道病毒可能导致严重且迅速发展的疾病，但目前的结果符合另一种假设，即轻微呼吸道疾病可能引发突然呼吸暂停。
