非典型肺炎并非是一个新名词。早在1930年底,医学界就将通常细菌以外的病原体所致的肺炎称之为非典型肺炎。上个世纪60年代,曾将当时发现的肺炎支原体作为非典型肺炎的主要病原体。但随后又发现了肺炎衣原体、军团菌和贝纳(伯氏)立克次体等病原体。尤其是肺炎支原体和肺炎衣原体引起的非典型肺炎占的比例最大。所以,对传统的非典型肺炎的诊断与治疗作以了解,很有必要。 SARS is not a new term. As early as the end of 1930, the medical profession called pneumonia, which is usually caused by pathogens other than bacteria, as atypical pneumonia. In the 1960s, Mycoplasma pneumoniae, which was discovered at that time, was used as the major causative agent of atypical pneumonia. However, subsequent discovery of pathogens such as Chlamydia pneumoniae, Legionella and Rickettsia. In particular, atypical pneumonia caused by Mycoplasma pneumoniae and Chlamydia pneumoniae accounted for the largest proportion. Therefore, it is necessary to understand the diagnosis and treatment of the traditional SARS.
