Presumably people have died of it, as South Africa has daily deaths and it’s most of the cases over there now.
I don’t think we can say it’s not a problem, clearly it is potentially a big problem. I still don’t think we should respond to every potential big covid problem by shutting down huge parts of peoples lives and livelihoods again. Or what’s going to stop is going the same next year, when there’s another new strain? And the year after that, and the year after that?
We can’t prevent all covid infections; all we could ever do, sort of, was try to delay most of them until we’d rolled out the vaccines. We have done that now. We can’t stay in an endless cycle of restrictions to humour the delusions of people who think covid would go away forever if only we were good enough.
