XE recombination arrives


Bottom line, Im not worried, but it is interesting

XE strain is a recombinant variant of BA.1 and BA.2

Mutation: an error is incorporated in the viral genome

Coinfecting: viruses exchange genetic information, creating a novel virus Changes to variant classification system

Variant of Concern: label a detrimental change in biological properties (changes in transmissibility, severity or immune evasion) compared to the current dominant variant(s); and a growth rate potentially compatible with maintaining transmission and/or displacing the current dominant variant.
