Healthcare facilities throughout the country are confronted with the task of preventing the transmission of tuberculosis among their patients and staff. On October 12, 1993, The Centers for Disease Control and Prevention published the Draft Guidelines for Preventing the Transmission of Tuberculosis in Health Care Facilities, and this is scheduled for final publication before year's end. The pending CDC guidelines are comprehensive and include engineering recommendations which are applicable to all settings in which health care is provided. Facilities that do not intend to use conventional construction or renovation to accomplish TB guideline compliance may consider using some type of environmental control device. These devices typically utilize ultraviolet germicidal irradiation (UVGI) and/or high efficiency particulate air filtration (HEPA), each of which is recognized as a viable TB environmental control. TB environmental control measures for specific areas within a healthcare facility should be based on a careful assessment of the actual risk of TB transmission in that setting.
全国各地的医疗机构都面临着防止结核病在患者和工作人员中传播的任务。1993年10月12日，疾病控制与预防中心发布了《医疗机构结核病传播预防指南草案》，该指南计划在年底前最终发布。疾病控制与预防中心即将发布的指南内容全面，包括适用于所有医疗服务场所的工程建议。不打算通过传统建设或翻新来符合结核病指南要求的医疗机构，可考虑使用某种类型的环境控制设备。这些设备通常利用紫外线杀菌辐照（UVGI）和/或高效空气微粒过滤（HEPA），其中每一种都被认为是可行的结核病环境控制手段。医疗机构内特定区域的结核病环境控制措施应基于对该场所结核病传播实际风险的仔细评估。
