Abstract
We studied the COVID-19 pandemic evolution in selected African countries. For each country considered, we modeled simultaneously the data of the active, recovered and death cases. In this study, we used a year of data since the first cases were reported. We estimated the time-dependent basic reproduction numbers, R0 , and the fractions of infected but unaffected populations, to offer insights into containment and vaccine strategies in African countries. We found that R0 ≤ 4 at the start of the pandemic but has since fallen to R0 ∼ 1 . The unaffected fractions of the populations studied vary between 1 - 10 % of the recovered cases.
