"SARS-CoV-2 Omicron Variant and Subvariants: The New Emergence, Recent Distribution and Global Impact"

KP.2, a new strain of the coronavirus, is attracting attention due to its advanced evolution relative to other Omicron variants. This strain effectively bypasses the established defenses against previous virus versions, resulting in a rise in reinfection cases, even among those recently vaccinated or previously infected. The “KP.2” strain, one of the “FLiRT” strains, is originally descended from the Omicron strain, according to data released by the Centers for Disease Control and Prevention.
