The subgroups of the coronavirus families are α, β, γ, and δ coronavirus. On June 15, 2021, the string λ of SARS-CoV-2 was evaluated as a variant of interest via the World Health Organization. This string has a high prevalence in some parts of South American countries, but it occurred only occasionally in Brazil. This study confirms that mutations in the λ-spike protein can be destroyed the neutralizing antibodies and increase infectivity. Coronaviruses such as SARS-CoV-2 have an evolutionary superpower called “recombination” which permits the mixing of their genomes into novel combinations. Unlike regular mutation, which precedes slowly one change at a time, recombination can produce whole changes in a coronavirus genome. Although right now, is a concern, a mixing of λ with other variants such as is much more of a concern compared to alone variants. There is another item: the recombination can arise within the sample after it was taken from the infected person, not while it was inside their body.trueCOVID-19 | Epsilon coronavirus | Iota coronavirus | Kappa coronavirus | Lambda coronavirus | Spike proteinsArticle10.33263/BRIAC125.689569142-s2.0-85119368420
