各国政府正在为一场潜在的流感大流行做准备。因此，他们需要数据来评估干预措施可能产生的影响。如果在常规情况下佩戴口罩有效，普通民众佩戴的口罩可能是一种可获得和负担得起的干预措施。我们评估了在健康志愿者和模拟患者的各种活动中佩戴个人呼吸器、外科口罩和自制口罩时所提供的传播减少潜力。所有类型的口罩都减少了气雾剂的暴露，随着时间的推移相对稳定，不受佩戴时间或活动类型的影响，但个体差异很大。个人口罩比医用口罩更有效，而医用口罩比国产口罩更有效。无论口罩的类型如何，儿童受到的保护都较差。向外防护(机械头戴口罩)不如向内保护(健康志愿者戴口罩)有效。任何类型的普通口罩的使用都可能在人群水平上降低病毒暴露和感染风险，尽管个人口罩提供了最大的保护。患者佩戴的口罩可能不会对气雾剂传播提供如此大程度的保护。
Governments are preparing for a potential influenza pandemic. Therefore they need data to assess the possible impact of interventions. Face-masks worn by the general population could be an accessible and affordable intervention, if effective when worn under routine circumstances. We assessed transmission reduction potential provided by personal respirators, surgical masks and home-made masks when worn during a variety of activities by healthy volunteers and a simulated patient. All types of masks reduced aerosol exposure, relatively stable over time, unaffected by duration of wear or type of activity, but with a high degree of individual variation. Personal respirators were more efficient than surgical masks, which were more efficient than home-made masks. Regardless of mask type, children were less well protected. Outward protection (mask wearing by a mechanical head) was less effective than inward protection (mask wearing by healthy volunteers). Any type of general mask use is likely to decrease viral exposure and infection risk on a population level, in spite of imperfect fit and imperfect adherence, personal respirators providing most protection. Masks worn by patients may not offer as great a degree of protection against aerosol transmission.
