Here's the only plan that exists in the US: get a viable vaccine out the door as fast as possible. Everything between now and that future point (likely next year) is a question mark. I simply can't see how "Test & trace" can even work logistically in a country as large and free of draconian government action as the US, especially given how many people here don't even take shelter in place seriously. So for now it's a game of watching the case count and asking how much economic damage we can take before things get really bad.
