Omicron constitutes the current strain of COVID-19 in circulation. “Omicron is very contagious. That was how it out-competed the Delta variant,” Dr. Yancey says.
This article aims at keeping an up-to-date list of Coronavirus strains and subspecies successfully isolated and cultured in laboratory, a task which is often challenging. When relevant it shall include a few synthetic chimera as well as some strains that were only propagated in laboratory animals.
SARS-CoV-2 is the virus that causes coronavirus disease 2019 (COVID-19). Some have been stated, to be of particular importance due to their potential for increased transmissibility, [1] increased virulence, or reduced effectiveness of vaccines against them.

Distinct from the PANGOLIN tool, Pango lineages are regularly, manually curated based on the current globally circulating diversity. A large phylogenetic tree is constructed from an alignment containing publicly available SARS-CoV-2 genomes, and sub-clusters of sequences in this tree are manually examined and cross-referenced against epidemiological information to designate new lineages; these ...
