That would seem to indicate that isolating nursing homes is a necessary, but not sufficient, step towards protecting seniors.The closest we have to "protect seniors" is Florida which took early steps to isolate nursing homes. Japan is also relatively close but they had mask mandates, curfew, lockdowns too (though less robust than Europe) and f'd the pooch when it comes to testing and vaccines. Some chose foolish policies with respect to seniors (including NY and Sweden). But pretty much everyone else was in the unsustainable lockdown boat with some exceptions (you know the ones).
FL still had 1.6 deaths per 100 confirmed cases. Better than the US average of 1.8 deaths per 100 confirmed cases, but not by much.
This is not exactly a great case study for the virtues of “protect seniors” as our main line of defense. Is there anywhere it actually worked?
