This topic is often raised on this forum and this paper makes the case for continued masking in hospitals.
Brief synopsis here
"Discontinuing masking outside of health care contexts is understandable. Immunity acquired by means of vaccination and infections, combined with the widespread availability of rapid diagnostics and effective treatments, has dramatically reduced the morbidity and mortality associated with SARS-CoV-2.
Most SARS-CoV-2 infections are now no more burdensome than the infections caused by influenza and other respiratory viruses that most people have long tolerated without feeling compelled to mask.
There are two reasons, however, why this framing has limited application to health care facilities.
Firstly, hospitalized patients are different from nonhospitalized populations. Hospitals, by definition, aggregate some of the most vulnerable people in society when they are at heightened vulnerability (i.e., when they have an acute illness).
Vaccines and treatments for SARS-CoV-2 have reduced the morbidity and mortality associated with SARS-CoV-2 infections for the majority of the population, but there remain important subgroups that continue to be at elevated risk for severe disease and death, including older adults, people who have immunocompromising conditions, and people who have severe coexisting conditions, such as chronic lung disease or heart disease.
Members of these groups constitute a large portion of hospitalized patients at any given time; many of them also make frequent visits to outpatient health care facilities."
