The Lancet published on 14 March 2020 an excellent, if technical, analysis titled "Preparedness and Vulnerability of African Countries against Importations of COVID-19: A Modelling Study" by a team of experts.
The study evaluates the preparedness and vulnerability of African countries against their risk of importation of coronavirus. Countries with the highest importation risk (Egypt, Algeria, and South Africa) have moderate to high capacity to respond to outbreaks. Countries at moderate risk (Nigeria, Ethiopia, Sudan, Angola, Tanzania, Ghana, and Kenya) have variable capacity and high vulnerability.
