COVID-19 has now spread to all the continents of the world with the possible exception of Antarctica. However, Africa appears different when compared with all the other continents. The absence of exponential growth and the low mortality rates contrary to that experienced in other continents, and contrary to the projections for Africa by various agencies, including the World Health Organization (WHO) has been a puzzle to many. Although Africa is the second most populous continent with an estimated 17.2% of the world's population, the continent accounts for only 5% of the total cases and 3% of the mortality. Mortality for the whole of Africa remains at a reported 19,726 as at August 01, 2020. The onset of the pandemic was later, the rate of rise has been slower and the severity of illness and case fatality rates have been lower in comparison to other continents. In addition, contrary to what had been documented in other continents, the occurrence of the renal complications in these patients also appeared to be much lower. This report documents the striking differences between the continents and within the continent of Africa itself and then attempts to explain the reasons for these differences. It is hoped that information presented in this review will help policymakers in the fight to contain the pandemic, particularly within Africa with its resource-constrained health care systems.
COVID-19 现已传播到世界各大洲,南极洲可能除外。然而,与其他各大洲相比,非洲似乎有所不同。与其他各大洲以及包括世界卫生组织(WHO)在内的各机构对非洲的预测相反,非洲没有出现指数级增长和低死亡率。尽管非洲是第二大人口大洲,拥有估计占世界人口 17.2%的人口,但该大陆仅占总病例的 5%,死亡人数占 3%。截至 2020 年 8 月 1 日,整个非洲的死亡率仍为报告的 19,726。大流行的开始较晚,增长率较慢,与其他各大洲相比,疾病的严重程度和病死率较低。此外,与其他各大洲记录的情况相反,这些患者的肾脏并发症的发生率似乎也低得多。本报告记录了各大洲之间以及非洲大陆内部的显著差异,并试图解释这些差异的原因。希望本综述中提供的信息将有助于决策者控制大流行,特别是在资源有限的非洲卫生保健系统中。
