In my opinion, we need at the very least the following, in no particular order, before we can start opening again:
Plentiful PPE for healthcare workers Widespread testing, that's no cost to the user whether they test positive or negative, so anyone can get tested Contact tracing needs set up/expanded, so we can trace the infections we do know about from the free testing People coming to the country need to be quarantined for 2 weeks and followed up with during that time Everyone needs to wear a mask in public
The shut down bought us a lot of time to figure out more about how the virus works. We could have done even more with the couple months we had before it really took off, but we didn't
If you ever find yourself in a fair fight, your tactics suck.
