Healthcare workers accounted for a large proportion of persons with severe acute respiratory syndrome (SARS) during the worldwide epidemic of early 2003. We conducted an investigation of healthcare workers exposed to laboratory-confirmed SARS patients in the United States to evaluate infection-control practices and possible SARS-associated coronavirus (SARS-CoV) transmission. We identified 110 healthcare workers with exposure within droplet range (i.e., 3 feet) to six SARS-CoV-positive patients. Forty-five healthcare workers had exposure without any mask use, 72 had exposure without eye protection, and 40 reported direct skin-to-skin contact. Potential droplet- and aerosol-generating procedures were infrequent: 5% of healthcare workers manipulated a patient's airway, and 4% administered aerosolized medication. Despite numerous unprotected exposures, there was no serologic evidence of healthcare-related SARS-CoV transmission. Lack of transmission in the United States may be related to the relative absence of high-risk procedures or patients, factors that may place healthcare workers at higher risk for infection.
在2003年初全球严重急性呼吸综合征(SARS)疫情期间,医护人员在感染该疾病的人群中占很大比例。我们对美国接触实验室确诊SARS患者的医护人员进行了一项调查,以评估感染控制措施以及可能的SARS相关冠状病毒(SARS-CoV)传播情况。我们确定了110名在飞沫传播范围内(即3英尺)接触6名SARS-CoV阳性患者的医护人员。45名医护人员在接触时未使用任何口罩,72名未采取眼部防护措施,40名报告有直接的皮肤接触。可能产生飞沫和气溶胶的操作很少见:5%的医护人员对患者气道进行了操作,4%的医护人员给予了雾化药物治疗。尽管存在大量无防护的接触,但没有血清学证据表明存在与医护相关的SARS-CoV传播。美国未出现传播可能与相对缺乏高风险操作或患者有关,这些因素可能使医护人员面临更高的感染风险。
