Covid-2019 - 2020-11-20
Date:
Saturday, November 21, 2020
Summary:
US testing is now almost at 3 million per day. The positivity rate is higher than in the summer surge, but far below the March-April peak. Spread is exponential, no doubt about that. Yet the 2-week case-fatality ratio is falling, so while the virus is spreading, its lethality is less fearsome than was thought six months ago.
