The XEC variant is the product of a recombination (exchanged pieces of genetic material between two variants) between the KS.1.1 variant and the KP.3.3 variant. These two parent variants are closely related, having both evolved from JN.1, which was the dominant variant around the world at the start of 2024.

There’s a new coronavirus subvariant catching the attention of global doctors and researchers: it’s being called “XEC.” Experts suspect this new strain of the coronavirus could become the dominant variant in a matter of months.
