根据大多数研究者的意见,应将非结核和非肿瘤性的肺-支气管病变列为慢性非特异性肺部疾病。在该病患病率增高的原因中,应当指出有急性呼吸系统疾病的普遍性、流感病毒的反复流行、急性支气管肺部疾病治疗不及时和不彻底、由于机体反应性改变使抵抗力降低以及工业危害。肺炎的菌种对抗菌素和磺胺类药物的耐药性增高以及日常生活中变态反应因子的数目增多有极重要意义。

Streptococcus pneumoniae strains of antibiotics and sulfa drugs increased resistance and increased daily life the number of allergic factors is extremely important.
