This study established segments among African countries to show the hierarchies of COVID-19 infection and death rates across the continent before the commencement of vaccination. Four clusters were extracted, each consisting of countries with a similar number of cumulative infections and deaths per 100 thousand population. When compared with the pre-vaccination figures from Europe, Americas, and Asia, it was observed that the African population exhibited a good level of rigidity and resilience to the pandemic, pre-vaccination. Majority of African countries - evaluating to 84% - were clustered into the segment with low infection and low death rates. Only 4% of the countries were clustered into the higher infection and highest death rates segment. This is an indication of the rigidity of a greater part of the African population to COVID-19 before vaccination. To forestall total business shutdown in the event of a similar pandemic in the future, multinational corporations could explore their workforce from the African population given the level of rigidity exhibited pre-vaccination.
本研究对非洲国家进行了划分，以展示在疫苗接种开始前整个非洲大陆新冠病毒感染率和死亡率的层级情况。提取了四个集群，每个集群由每十万人口中累计感染和死亡人数相似的国家组成。与欧洲、美洲和亚洲疫苗接种前的数据相比，观察到非洲人群在疫苗接种前对疫情表现出了良好的抵抗力和恢复力。大多数非洲国家——占比84%——被归为感染率低和死亡率低的类别。只有4%的国家被归为感染率较高和死亡率最高的类别。这表明在疫苗接种前，非洲大部分人群对新冠病毒具有抵抗力。为防止未来发生类似疫情时企业全面停工，跨国公司鉴于非洲人群在疫苗接种前表现出的抵抗力，可以考虑从非洲招募员工。
