A study on acute respiratory infectious was carried out in four kindergartens in Beijing from September, 1984 to August, 1987. The results showed that ARI incidence rate in the children aged 0-7 years was 348.3%. Most of the cases were upper respiratory infectious. The incidence rate of pneumonia was 2.7%. The relationship between ARI incidence rate and age group showed that incidence of URI of 0-2 age group was 1.5 times higher than that of 5-7 age group, while the incidence of LRI of that 0-2 age group was 6.3 times higher than the later age group. The peak season of ARI was from October to January each year. The virus infections showed its priority in ARI. Duplicate samples of sera of 240 cases were tested. In which 122 cases were proved positive. Some strains of virus were isolated as well. It was showed that the influenza virus and adenovirus were the common pathogens of ARI. The effect of killed BCG(orally) on preventing ARI was observed. The preliminary date indicated the potential effect for the prevention of ARI by this measure.
1984年9月至1987年8月期间，在北京的四所幼儿园开展了一项关于急性呼吸道感染的研究。结果显示，0至7岁儿童的急性呼吸道感染发病率为348.3%。大多数病例为上呼吸道感染。肺炎发病率为2.7%。急性呼吸道感染发病率与年龄组之间的关系表明，0至2岁年龄组的上呼吸道感染发病率比5至7岁年龄组高1.5倍，而该年龄组的下呼吸道感染发病率比后一年龄组高6.3倍。急性呼吸道感染的高峰季节是每年的10月至1月。病毒感染在急性呼吸道感染中占主导地位。对240例病例的血清重复样本进行了检测。其中122例被证明呈阳性。还分离出了一些病毒株。结果表明，流感病毒和腺病毒是急性呼吸道感染的常见病原体。观察了口服灭活卡介苗对预防急性呼吸道感染的作用。初步数据表明该措施对预防急性呼吸道感染有潜在效果。
