Covid-2019 - 2020-11-19
Date:
Friday, November 20, 2020
Summary:
According to our days-to-double fatalities metric, Covid-19 is now spreading "exponentially" in the US. The temptation to do more lockdowns -- which show no evidence of helping -- is ever-present. We've seen short periods of exponential spread before, and it's not clear what causes it, or what always eventually ends it. This morning Pfizer applied for emergency authorization for its new vaccine, and that's going to be a game changer.
