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.
2019 年冠状病毒病（COVID-19）大流行已蔓延至非洲的 55 个国家。该病的流行情况差异很大，多数病例为无症状。人们认为有几个因素可以解释非洲 COVID-19 存在差异，包括遏制措施的水平、人口统计学方面、气候和环境因素、宿主遗传和免疫因素。在此，我们讨论了 COVID-19 在非洲的流行情况、血清学研究现状、COVID-19 与合并症、SARS-CoV-2 变异株的传播以及非洲疫苗接种情况。
