As the SARS-CoV-2 pandemic continues to explode, hospital systems are scrambling to intensify their measures for protecting patients and health care workers. Providers are wondering whether this effort should include universal use of masks by all health care workers. Wearing a mask outside health care facilities offers little, if any, protection from infection. Public health authorities define a significant exposure to Covid-19 as face-to-face contact within 6 feet with a patient with symptomatic Covid-19 that is sustained for at least a few minutes (and some say more than 10 minutes or even 30 minutes). The chance of catching Covid-19 from a passing interaction in a public space is therefore minimal. In many cases, the desire for widespread masking is a reflexive reaction to anxiety over the pandemic. The calculus may be different, however, in health care settings. There are two scenarios in which there may be possible benefits. The first is during the care of a patient with unrecognized Covid-19. More compelling is the possibility that wearing a mask may reduce the likelihood of transmission from asymptomatic and minimally symptomatic health care workers with Covid-19 to other providers and patients. A mask will not protect providers caring for a patient with active Covid-19 if its not accompanied by meticulous hand hygiene, eye protection, gloves, and a gown. Focusing on universal masking alone may, paradoxically, lead to more transmission of Covid-19 if it diverts attention from ... more fundamental infection-control measures.
