An outbreak of influenza virus type B infection occurred in Philadelphia from December, 1985, to April, 1986. During this epidemic 24 patients were admitted to Children's Hospital from whom influenza B was isolated from routine respiratory viral cultures. All were younger than 3 years of age. Clinical findings included fever (greater than or equal to 38 degrees C) (88%), rhinorrhea (62.6%), cough (50%), otitis (50%), rhonchi (42%), vomiting (38%), diarrhea (33%), rales (21%), pharyngitis (13%) and croup (4%). Remarkably 75% of the patients had underlying diseases which may have contributed to the severity of the infection. Nine (41%) patients had pneumonia. Two patients died of respiratory failure caused by overwhelming influenza B virus infection. Patients admitted to the hospital with respiratory and underlying diseases should have viral respiratory cultures which include influenza B.
1985年12月至1986年4月，费城爆发了乙型流感病毒感染。在这次疫情期间，24名患者被送往儿童医院，从他们的常规呼吸道病毒培养物中分离出了乙型流感病毒。所有患者年龄均小于3岁。临床症状包括发热（≥38℃）（88%）、流涕（62.6%）、咳嗽（50%）、中耳炎（50%）、哮鸣音（42%）、呕吐（38%）、腹泻（33%）、湿啰音（21%）、咽炎（13%）和哮吼（4%）。值得注意的是，75%的患者有基础疾病，这可能导致了感染的严重程度。9名（41%）患者患有肺炎。两名患者死于乙型流感病毒感染导致的呼吸衰竭。因呼吸道疾病和基础疾病入院的患者应进行包括乙型流感病毒在内的病毒性呼吸道培养。
