IntroductionCurrently, the face mask represents an incomparable symbol whose value went from clinical work to impacting the containment of the spread of SARS-CoV-2, although it has become an element of discord in the general population.ObjectiveTo establish the impact of face mask use policies on COVID-19 morbidity and mortality.MethodsFace mask use policy variables, obtained from the website of the #Masks4All scientific movement, were associated with the number of infections, deaths and flattening of the curve published by the Johns Hopkins University resource center and EndCoronavirus.org.ResultsFace mask use policies were universal (required in shops, restaurants, public transport), partial (recommended, required in any public place) and absent. Associations of the face mask use policy with total cases (p = 0.01), cases per million (p = 0.04) and deaths per million population (p = 0.02) were statistically significant. Associations of the variables with the epidemiological curve trend were also statistically significant (p = 0.00).ConclusionThe recommendation for face mask widespread use is a measure with sufficient scientific support to reduce the number of COVID-19-related infections and deaths.Copyright: © 2021 Permanyer.
