Yeah, the spike mutations would suggest chronic - but a lot of mutations outside spike too, which is a little peculiar tome.

In context

A single line often inverts meaning once you see what it answers, so neighbouring messages are always shown.

Yes, agreed. Although reinfections also a concern here - I'm worried about selection in e.g., healthcare settings.Mink transmission also a concern here.My default is always "probably not an issue", but SARS2 really does appear to be pretty 'adaptable' and there's ALOT of transmission going on.

That's A LOT of mutations - all in one 'jump'?

There is one intermediate with some of the mutations... hence thought of a chronic shedder

Chronic shedding with immune selection definitely a possibility. N501 is next to a short disordered region in S structures - a clear signal that it's an epitope.

P681H is also VERY interesting....how common is this?

There is an ORF8 stop at amino acid 27 and then a number appear after that suggesting it has become non functional.

@Robert Garry Why do you say that?
