自2003年3月起,一种称为严重急性呼吸综合症(Severe acute respiratory syndrome,SARS)的急性传染病开始在北京流行,该病起病急,传染性强,病死率较高。患者主诉发热、咳嗽、无痰或少量白色粘痰,双肺呼吸音粗,X光检查特别在后期两肺内可见弥漫性模糊的密度增高片状阴影,CT检查两肺纹理不清,斑片状密度稍高病灶。呼吸道的症状、体症及影象学改变均表明肺脏是本病的主要病变部位。我们曾对3例SARS死亡患者进行了病理解剖,观 Since March 2003, an acute infectious disease called Severe acute respiratory syndrome (SARS) has started to emerge in Beijing. The disease is acute, contagious and has a high case fatality rate. Patients complained of fever, cough, phlegm or a small amount of white phlegm, lung breath sounds crude, X-ray examination, especially in the latter two lungs were seen diffuse blurred density increased sheet shadow, CT examination of lungs unclear, patch Density slightly higher lesions. Respiratory symptoms, physical disease and imaging changes indicate that the lungs are the main lesion site. We have performed pathological anatomy and observations on three deaths from SARS
