The Delta variant (B.1.617.2 and AY. *) of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has triggered a massive wave of new infections and re-emergent outbreaks around the globe, making the eradication of the coronavirus disease 2019 (COVID-19) a more distant goal and adding significant uncertainty to the future of mankind

Transmissions of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Delta variant around the globe (top). Phylogeny of the Delta variant of 3948 genomes collected between January 2021 and November 2021 (bottom). Source: global initiative on sharing all influenza data (GISAID 2021). GISAID is the largest open-access portal, hosting the genome sequences and related epidemiological and clinical data of more than 5.6 million SARS-CoV-2 strains. All data were last updated on 30 November 2021

The Delta variant has higher transmissibility compared with the original severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), and has become the dominating causation agent of newly confirmed infections in the global population, as of 30 November 2021

Mutations of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with its main variants identified to date. The Delta variant, which includes the B.1.617.2 and AY.* pango lineages, has become the dominant causation agent of coronavirus disease 2019 (COVID-19) infections reported around the globe. As of 30 November 2021, a total of 407 pango lineages have emerged since the onset of the COVID-19 pandemic. The continuing massive scale of transmission of SARS-CoV-2 and its variants may lead to the emergence of potentially more dangerous 'super-variants' in the future
