自非洲发现首例COVID-19病例以来的三个月，非洲大陆几乎所有国家的发病率和死亡率继续低于全球趋势，包括欧洲和北美。我们回顾了各种假设的优点，以解释这一现象，包括低播种率，有效的缓解措施，人口更年轻，有利的天气，并可能事先暴露于交叉反应病毒。人口年轻化和气候适宜似乎很有吸引力，特别是它们的综合效应;然而，该地区和全球大流行的进展可能会在未来几个月内消除这些因素。
Three months since the detection of the first COVID-19 case in Africa, almost all countries of the continent continued to report lower morbidity and mortality than the global trend, including Europe and North America. We reviewed the merits of various hypotheses advanced to explain this phenomenon, including low seeding rate, effective mitigation measures, population that is more youthful, favorable weather, and possible prior exposure to a cross-reactive virus. Having a youthful population and favorable weather appears compelling, particularly their combined effect; however, progression of the pandemic in the region and globally may dispel these in the coming months.
