Recurrent or persistent lower respiratory disease in children may present in various ways. The differential diagnosis includes reactive airways disease (asthma), prolonged viral pneumonia (in the young infant) and foreign body aspiration-the most common causes of persistent respiratory symptoms. The differential diagnosis also includes a long list of rare conditions. Because of the many diagnostic possibilities, the evaluation of a child with persistent lower respiratory disease should be carried out in a systematic, stepwise fashion.
儿童复发性或持续性下呼吸道疾病可能有多种表现形式。鉴别诊断包括反应性气道疾病（哮喘）、迁延性病毒性肺炎（见于幼儿）和异物吸入——持续性呼吸道症状最常见的病因。鉴别诊断还包括一长串罕见病症。由于存在多种诊断可能性，对患有持续性下呼吸道疾病的儿童进行评估时应采用系统、逐步的方式。
