[The weekly cycle of mortality among patients with COVID-19]

The statistical data on mortality due to COVID-19 has been studied. The weekly cycle of mortality was established. Presumably, the decreased mortality on particular days of the week related to optimized treatment protocols applied on the «favorable days». If the factors reducing mortality on particular days of the week could be identified, their positive effect should be applied to other days of the week to decrease mortality among patients with COVID-19.
