  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 have since fallen to R₀~1. The unaffected fractions of the populations studied vary between 1%-10% of the recovered cases. .. View more»
