The fact is that we must develop a strategic mitigation plan to take us up through the point when a vaccine can be deployed. That plan must allow for low level spread. Several Far East Asian countries are already showing that mandatory mask usage coupled with reasonable self-isolation measures can slow the spread enough to not overwhelm their medical systems. The usage of masks also limits the initial viral load being received which is expected to lead to fewer bad outcomes. Since over half of us will probably get infected, and the herd immunity is a good thing, the goal among young healthy people should be to limit that initial viral load, rather than taking extreme measures to avoid infection.
After the initial spread is halted we need to resume work, using masks and distancing to limit the spread. Large gatherings and eating and drinking in public should be avoided and at risk populations should remain more isolated as much as possible. The second wave may end up fairly flat or we may have to go through a number of saw-tooth-like peaks where the virus spreads and stricter quarantine measures are applied to stop it. The experience in the Far East tells us that keeping it fairly flat should be possible.
The first known infection in Wuhan (not detection) occurred between 10 and 11 weeks before the quarantine. So that gives us a window that masks, isolation, and quarantine measures must be deployed well before the 10 week mark for infections in any large community in order to avoid higher mortality rates. Smaller communities must act sooner. This varies for every state and major city in the US, but the clock is ticking on the ones who are not taking enough action. Masks should already be mandatory in public and in work environments where people share an open space or HVAC system.
