Based on their experience, what we should have been doing is:
- Lock down enough to really get the numbers down, with the understanding that it's temporary, because:
- While locked down, really beef up the test and trace infrastructure. After the numbers are reasonable, this lets you open up but find and isolate individual cases.
- Encourage/require mask wearing by anyone in public. Studies have shown that 80% mask wearing reduces the virus by over 90%.[1]
- Instead of putting money into unemployment, pay businesses to keep people on salary while they're not working. That way the jobs are still there when we open back up. European countries have done this, kept unemployment low, and in some cases spent less per GDP than the US.[2]
The earlier you start, the easier and more effective all this is. If you start early enough and already have good systems in place, you can even skip the lockdown step, aside from localized outbreaks.
