Manaus, Brazil, had a very hard first wave. Seroprevalence surveys indicated at least 44% had antibodies and extrapolation suggested 76%, which means that Manaus should have achieved herd immunity.
But Manaus is having a second wave, and it has already made more people seriously ill than the first.
Node, take good note.
