SARS-CoV-2 variants of concern pose a higher risk for hospitalisation and intensive care admission

Since the discovery of SARS-CoV-2, three variants of concern (VOC), first identified in the United Kingdom (B.1.1.7), South Africa (B.1.351), and Brazil (P.1), have been associated with higher transmissibility and severity of disease, with potential implications for acquired immunity or the effectiveness of current vaccines.
