目的 :探讨控制SARS医院感染的措施及评价。方法 :选择某医院 2 0 0 3年 3～ 4月医院感染的SARS病例 ,进行流行病学调查。结果 :①共发生医院感染病例 30例。②流行病学特点 :在 3月中旬和下旬有 2个发病高峰 ,病例主要集中住院大楼西单元的 5个楼层的 4、5号病房 ,住院患者多年龄大且合并较重基础病 ,而受染医护人员以一线中青年为主。③输入性病例是导致医院感染的第一代传染源 ,医院内传染的住院者和医护人员是SARS进一步扩散的继发传染源。④研究发现 :近距离空气传播和密切接触传播为本次SARS医院感染的主要传播途径 ,并存在气溶胶经病房排风系统垂直长距离传播的可能性。结论 :医院感染是SARS流行初期的主要形式。通过控制传染源 ,增设发热门诊及隔离病房 ,建立医学观察区 ,病区通风和消毒 ,严禁探视和加强人员防护等措施 ,医院内感染得到有效控制 Objective: To explore the measures and evaluation of SARS control in hospital. Methods: SARS cases of nosocomial infection from March to April 2003 in a hospital were selected for epidemiological investigation. Results: There were 30 cases of nosocomial infections in total. ② epidemiological characteristics: the peak incidence in mid-March and late 2, the cases mainly concentrated in the hospital unit 5 West Wing Ward 4,5 Ward, hospitalized patients with more age and severe underlying disease, and by Dyeing medical staff to the first-line middle-aged. (3) The imported cases are the first generation of infectious agents that cause nosocomial infection. Inpatients and medical workers infected with nosocomial infection are secondary sources of SARS further spread. (4) The study found that close air transmission and close contact transmission are the main routes of SARS hospital infection, and there is a possibility that aerosols will spread vertically and vertically through the ward ventilation system. Conclusion: Nosocomial infection is the main form of SARS epidemic. By controlling the sources of infection, adding out-patient clinics and isolation wards, setting up medical observation areas, ward ventilation and disinfection, non-visit and strengthening of personnel protection measures, effective control of the hospital infection
