How did the CDC's Natalie Thornburg describe the coronavirus's pattern of strain dominance and emergence of descendants?
Socrates
CDC's Natalie Thornburg described the coronavirus's pattern of strain dominance and emergence of descendants as a consistent phenomenon. According to Thornburg, a dominant "parent" strain takes hold in early winter, and by spring, a handful of descendants emerge. This pattern was observed with the XBB strain last year, which dominated in the winter but gave rise to offshoots in the spring. The same pattern was also seen with the JN.1 variant and its descendants.
