Marsha,
If we are at 0.63, we will get case numbers down fast to a very low level.
Then they will very gradually unlock and monitor new cases. Theoretically we could have more freedom and still keep the number around one at that point.
It is far from ideal, and also unsustainable long term, but the best we have to aim for right now.
What concerns me is the seeming lack of big spend on research. I hear of a few 10s of millions here and there but, compared to the hundreds of billions (or even trillions) thrown at the economy, it is chicken feed. And it seems really badly co-ordinated, rather than a global effort.
I don’t understand the lack of a Covid ‘Manhattan project’, even within the U.S or Europe. Treatment and a vaccine are the only real way out (or herd immunity accepting many millions of deaths worldwide).
