SARS-CoV-2: Searching for the Missing Variants.

Viruses - 26 Oct 2022

Caputo Emilia, Mandrich Luigi

Abstract excerpt

Structural and phylogenetic analysis of the spike glycoprotein highlighted that the last variants, annotated as omicron, have about 30 mutations compared to the initial version reported in China, while the delta variant, supposed to be the omicron ancestor, shows only 7 mutations. Moreover, the five omicron variants were isolated between November 2021 and January 2022, and the last variant BA.2.75, unofficially...
