We recruited 688 hospital healthcare workers who cared for patients with severe acute respiratory syndrome (SARS) and did not develop the disease in the Hong Kong outbreak in 2003. A questionnaire survey was conducted and serum samples were collected for SARS-associated coronavirus (SARS-CoV) antibody. The high-risk procedures performed and the types of unprotected exposures were recorded for analysis. Only 1 asymptomatic nurse had positive serological test. The result demonstrates the low rate of subclinical SARS-CoV infection in hospital healthcare workers and that the infection control practice against SARS in Hong Kong's hospitals during the outbreak was highly effective.
我们招募了688名在2003年香港严重急性呼吸系统综合症（SARS）疫情期间照顾SARS患者但未发病的医院医护人员。进行了问卷调查，并采集血清样本检测SARS相关冠状病毒（SARS-CoV）抗体。记录所执行的高风险操作和未受保护暴露的类型以供分析。只有1名无症状护士血清学检测呈阳性。结果表明医院医护人员中SARS-CoV亚临床感染率较低，且疫情期间香港医院针对SARS的感染控制措施非常有效。
