From winter 1989 to spring 1990, a severe epidemic caused by influenza A (H3N2) and B viruses developed in Japan. During the epidemic (December 1989 to February 1990), 244 children were admitted to the pediatric ward of Nippon Kokan Hospital: 53 (21.7%) were hospitalized with influenza virus infection, 22 (9.0%) with rotavirus gastroenteritis, and 17 (7.0%) with respiratory syncytial virus infection. Among those with influenza, 24 had type A and 29 had type B. Most were young healthy children without underlying illnesses (mean age, 4.8 +/- 3.4 years). The impact of the influenza epidemic on pediatric hospitalization is probably much greater than generally thought when a severe epidemic occurs.
1989年冬到1990年春，日本爆发了由甲型（H3N2）和乙型流感病毒引起的严重疫情。在疫情期间（1989年12月至1990年2月），244名儿童住进了日本钢管医院的儿科病房：53名（21.7%）因感染流感病毒住院，22名（9.0%）因感染轮状病毒患肠胃炎住院，17名（7.0%）因感染呼吸道合胞病毒住院。在流感患者中，24名感染甲型流感病毒，29名感染乙型流感病毒。大多数是没有基础疾病的健康幼儿（平均年龄4.8±3.4岁）。当发生严重疫情时，流感疫情对儿科住院率的影响可能比一般认为的要大得多。
