The worldwide outbreak of coronavirus disease-19 (COVID-19) has already put healthcare workers (HCWs) at a high risk of infection. The question of how to give HCWs the best protection against infection is a priority.
We searched systematic reviews and original studies in Medline (via Ovid) and Chinese Wan Fang digital database from inception to May, 2020, using terms 'coronavirus', 'health personnel', and 'personal protective equipment' to find evidence about the use of full-body PPEs and other PPEs by HCW exposed highly infectious diseases.
Covering more of the body could provide better protection for HCWs. Of importance, it is not just the provision of PPE but the skills in donning and doffing of PPE that are important, this being a key time for potential transmission of pathogen to the HCW and in due time from them to others. In relation to face masks, the evidence indicates that a higher-level specification of face masks and respirators (such as N95) seems to be essential to protect HCWs from coronavirus infection. In community setting, the use of masks in the case of well individuals could be beneficial. Evidence specifically around PPE and protection from the COVID-19 virus is limited.
Covering more of the body, and a higher-level specification of masks and respirators could provide better protection for HCWs. Community mask usecould be beneficial. High quality studies still need to examine the protection of PPE against COVID-19.
新型冠状病毒病（COVID-19）的全球爆发已经使医护人员（HCWs）面临高度感染的风险。如何为 HCWs 提供最佳的感染防护是当务之急。
我们在 2020 年 5 月之前，通过 Medline（通过 Ovid）和中国万方数字数据库，使用“冠状病毒”、“卫生人员”和“个人防护设备”等术语，搜索了系统评价和原始研究，以寻找有关高度传染性疾病暴露的 HCW 使用全身 PPE 和其他 PPE 的证据。
覆盖更多的身体可以为 HCWs 提供更好的保护。重要的是，不仅要提供 PPE，还要掌握穿戴和脱下 PPE 的技能，这是病原体向 HCW 潜在传播的关键时期，也是 HCW 向他人传播的关键时期。关于口罩，证据表明，更高规格的口罩和呼吸器（如 N95）似乎对于保护 HCWs 免受冠状病毒感染是必要的。在社区环境中，健康人使用口罩可能是有益的。关于 PPE 及其对 COVID-19 病毒的保护的证据有限。
