非典型肺炎非典型肺炎实际是与由细菌引起的所谓典型肺炎不同的一组肺炎,曾泛指细菌以外的病原体所致的肺炎。现在主要指由支原体、衣原体、军团菌、立克次体、腺病毒以及其他一些不明微生物引起的急性呼吸道感染伴肺炎。这些病原体亦称非典型病原体。非典型肺炎主要通过近距离空气飞沫和密切接触传播,是一种呼吸道急性传染病,有比较强的传染力。世界卫生组织将传染性非典型肺炎称为严重急性呼吸综合征(SevereAcuteRespiratorySyndrome,SARS)。 SARS is actually a different group of pneumonia than the so-called classic pneumonia caused by bacteria, which has been generally referred to as pneumonia caused by pathogens other than bacteria. Now mainly refers to the acute respiratory infections caused by Mycoplasma, Chlamydia, Legionella, Rickettsia, adenovirus and other unknown microorganisms with pneumonia. These pathogens are also known as atypical pathogens. SARS is mainly spread through close-spaced air droplets and close contact. It is an acute respiratory infectious disease with strong contagious power. WHO calls SARS pneumonia Severe Acute Respiratory Syndrome (SARS).
