I still think all three are chronic cases which have selected for antigenic escape within the host (and for B.1.1.7 atleast increased transmissibility) and then these turned out to be in places where these were very fit.

In context

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

    Exactly

    That's weird. I mean, P.1. has many overlapping mutations so surely those at least must be right?

    I thought they were more likely reversions than intermediates (still unlikely) but when I pointed them out to Tulio hesaid he thought they weren't real and they were fixing them.

    Oh.

    Otherwise we would see these combinations coming up a lot.

    Yeah, that's true - either strong bottleneck (in single host) or very strong selection.

    Not to say they couldn't given enough time but the chronic patient is just a kickstart

    Such an interesting virus evolutionarily speaking - I _do_ wonder what other shit it'll throw after us.
