In this report, we sought to examine whether an early implementation of face mask use with an achievable adherence of 80% in the population would have reduced cumulative COVID-19 incidence, mortality, and the number of hospital and intensive care unit(ICU)admissions, as compared to the observed epidemiological situation. We considered an adherence rate of 80% as achievable because this rate was achieved at the time of the second lockdown in late October [5]. This knowledge is crucial when the hypothesis of repeated rebounds of the epidemic until its end, and particularly when protection measures are relaxed, cannot be ruled out.
