If you've "almost" fully recovered, i.e. still showing symptoms, you're still shedding viral particles when you go out and putting others at risk. Wait 14 days after all symptoms have totally subsided, then going out would be relatively safe. But really, you should have multiple tests to be sure.
Yes. Staying at home is key. Everybody should do that. And people in the US should probably have been doing that at least one or two weeks earlier.
Some countries are a little ahead though. I mean not just socially, but in the spreading of Corona and figuring out what works and what doesn't. Sometimes there are clear rules and guidelines in some cases the military is even enforcing national corona policies.
So when we're all used to staying home and that is working. We should not forget about the economy and start figuring out ways to kickstart it.
