The coronavirus disease 2019 (COVID-19) pandemic has spread to all 55 countries in Africa. The prevalence is highly heterogeneous, and the majority of cases are asymptomatic. Several factors are thought to explain heterogeneity of COVID-19 in Africa, including the level of containment measures, demographic aspects, climate and environmental factors, host genetics and immune factors. Here, we discuss the prevalence of COVID-19 in Africa, the status of serological studies, COVID-19 and comorbidities, as well as the spread of SARS-CoV-2 variants and the status of vaccine roll-outs in Africa. In this Comment article, Sofonias Tessema and John Nkengasong provide an overview of the current state of the COVID-19 pandemic in Africa and the challenges posed by the triple burden of emerging, endemic and non-communicable diseases.

了解非洲的 COVID-19

2019 年冠状病毒病 (COVID-19) 大流行已蔓延至非洲所有 55 个国家。患病率具有高度异质性，大多数病例没有症状。有几个因素被认为可以解释非洲 COVID-19 的异质性，包括遏制措施的水平、人口统计方面、气候和环境因素、宿主遗传学和免疫因素。在这里，我们讨论了 COVID-19 在非洲的流行情况、血清学研究的状况、COVID-19 和合并症，以及 SARS-CoV-2 变体的传播和疫苗在非洲的推广情况。在这篇评论文章中，Sofonias Tessema 和 John Nkengasong 概述了非洲 COVID-19 大流行的现状以及新兴疾病、地方病和非传染性疾病的三重负担所带来的挑战。
