During outbreaks, hospital workers are at high risk for nosocomial infection with severe acute respiratory syndrome (SARS)-associated coronavirus.
To examine how hospital workers became infected and whether they transmit the virus to their families.
Retrospective descriptive study.
529-bed community hospital in Hong Kong.
40 hospital workers infected with SARS-associated coronavirus over a 6-week period (25 March through 5 May 2003).
Percentage of infected hospital workers according to job category.
The cumulative incidence was highest among health care assistants, followed by physicians and nurses (8%, 5%, and 4%, respectively). Most hospital workers were infected from direct contact with patients with SARS, who primarily were in general wards and had unsuspected infection. At the time of contact, all hospital workers had used masks but not necessarily other protective devices. Affected hospital workers did not infect their families.
Before isolation of all patients with clinically confirmed or suspected SARS, routine use of several protective devices, and training of staff in infection control, many health care workers were infected with SARS from patients with unsuspected cases.
在疫情暴发期间，医院工作人员感染严重急性呼吸综合征（SARS）相关冠状病毒的医院感染风险很高。
研究医院工作人员是如何被感染的，以及他们是否将病毒传播给家人。
回顾性描述性研究。
香港一家拥有529张床位的社区医院。
在6周时间内（2003年3月25日至5月5日）感染SARS相关冠状病毒的40名医院工作人员。
按工作类别划分的感染医院工作人员百分比。
医护助理的累积发病率最高，其次是医生和护士（分别为8%、5%和4%）。大多数医院工作人员是通过与SARS患者直接接触而感染的，这些患者主要在普通病房，且感染未被怀疑。接触时，所有医院工作人员都佩戴了口罩，但不一定使用了其他防护设备。受感染的医院工作人员没有将病毒传播给家人。
在隔离所有临床确诊或疑似SARS患者、常规使用多种防护设备以及对工作人员进行感染控制培训之前，许多医护人员被未被怀疑感染的患者感染了SARS。
