New lineage to add to the 'active' list.
The TX lineage reappeared (BA.1-derivative); hadn't seen it in a year.
Classic mutations: K1795Q, K417T, H182D, S37P, s2M-fix, etc.
Cryptic (gain-of-function) lineage update.
There are currently 7 cryptic lineages in the US that I consider ‘active’.
This is a rundown.
Warning, I’m going into the weeds.
Nerds only.
