项目摘要

During COVID-19 pandemic, severe shortage in disposable filtering facepiece respirators such as N95 respirators and surgical masks, have been reported in most if not all countries. This shortage is of grave concern, particularly among frontline healthcare workers as well as other frontline workers in contact with the public during a pandemic. In the absence of certified respirators, the public might improvise face masks using common household materials. However, there is limited evidence about the performance of these materials in protecting the user against bioaerosols. The objectives of this research are to study the performance of select household materials for use in homemade masks and recommend suitable configurations for select household materials to achieve a performance similar to N95 respirator material. This research is aligned with the government effort to protect the public and frontline workers, given the shortage of N95 respirators and surgical masks during COVID-19 pandemic and possibly future respiratory infection outbreaks. The results from this research can be used to guide the public on selecting appropriate material for making face masks, which can ease the demand on N95 respirators and surgical masks needed for frontline health workers. The results from this research will be made public for the benefit of the general population.

在COVID-19大流行期间，大部分（如果不是所有）国家均报告了一次性过滤面罩呼吸器（如N95呼吸器和外科口罩）的严重短缺。这种短缺令人严重关切，尤其是在大流行期间与公众接触的前线医护人员和其他前线工作人员。在没有经过认证的消毒师的情况下，公众可能会使用普通的家用材料临时制作口罩。然而，关于这些材料在保护用户免受生物气溶胶侵害方面的性能的证据有限。本研究的目的是研究用于自制口罩的选定家用材料的性能，并为选定的家用材料推荐合适的配置，以实现与N95呼吸器材料相似的性能。鉴于在COVID-19大流行期间以及未来可能爆发的呼吸道感染期间，N95呼吸机和外科口罩短缺，这项研究与政府保护公众和前线工作人员的努力保持一致。这项研究的结果可以用来指导公众选择合适的材料来制作口罩，这可以缓解前线卫生工作者对N95呼吸机和外科口罩的需求。这项研究的结果将公之于众，以造福广大民众。
