Document: We applied a recently developed deterministic compartmental mathematical model that describes the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) transmission dynamics and disease progression in a population [1] , to all countries and territories with a population of at least one million, as of 2020 [7] . An illustration of the basic model structure can be found in A system of coupled nonlinear differential equations is used to describe SARS-CoV-2 transmission dynamics. Nine age cohorts were considered ( ) 1, 2,...,9 a = , each representing a ten-year age band apart from the last cohort which includes individuals aged ≥80 years. The agespecific distribution for each country/territory, as of the year 2020, was obtained from the United Nations World Population Prospects database [7] . All disease-related mortality was assumed to occur in individuals that are in the critical disease stage, as informed by the China outbreak data [5] .
