The largest outbreak of severe acute respiratory syndrome (SARS) struck Beijing in spring 2003. Multiple importations of SARS to Beijing initiated transmission in several healthcare facilities. Beijing's outbreak began March 5; by late April, daily hospital admissions for SARS exceeded 100 for several days; 2,521 cases of probable SARS occurred. Attack rates were highest in those 20-39 years of age; 1% of cases occurred in children <10 years. The case-fatality rate was highest among patients >65 years (27.7% vs. 4.8% for those 20-64 years, p < 0.001). Healthcare workers accounted for 16% of probable cases. The proportion of case-patients without known contact to a SARS patient increased significantly in May. Implementation of early detection, isolation, contact tracing, quarantine, triage of case-patients to designated SARS hospitals, and community mobilization ended the outbreak.

2003年春季，严重急性呼吸综合征（SARS）在北京爆发规模最大。SARS多次输入北京，在多家医疗机构引发传播。北京的疫情于3月5日开始；到4月下旬，SARS的每日住院人数连续数天超过100人；共出现2521例可能的SARS病例。发病率在20至39岁人群中最高；10岁以下儿童的病例占1%。病死率在65岁以上患者中最高（27.7%，20至64岁患者为4.8%，p<0.001）。医护人员占可能病例的16%。5月份，与SARS患者无已知接触的病例比例显著增加。实施早期检测、隔离、接触者追踪、检疫、将病例分诊至指定的SARS医院以及社区动员后，疫情结束。
