20 0 3年 1月 2日广东省卫生厅首次接到传染性非典型肺炎聚集性病例的报告 ,即日组织现场调查 ,之后国内其他部分省市自治区相继出现疫情。该类肺炎与已知的由肺炎支原体、肺炎衣原体、军团菌及常见的呼吸道病毒所致的非典型肺炎不同 ,其传染性强 ,病情较重、进展快 ,危害大。 On January 2, 2003, Guangdong Provincial Department of Health reported for the first time a report of cases of the accumulation of SARS. After that, it conducted an on-site field investigation, and other provinces, autonomous regions and municipalities in China later reported outbreaks one after another. Unlike the known atypical pneumonia caused by Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella and common respiratory viruses, this type of pneumonia is highly contagious, has a severe condition, progresses rapidly and is detrimental.
