Hi Min,
Are you asking for just the U. S., or the world in general?
Here in Australia we went hard and early with social restrictions and are on the verge of eradication, although I hate using that term because it could turn around fast if things go wrong.
Restaurants were still allowed to serve take out but no club's, bars or big gatherings. We can still go for a walk and shop for groceries but still maintain distancing while doing these activities. A lot of people are working from home.
I know the economic figures are going to be bad, but the economy is still functioning to an extent, also, the government has offered various generous stimulus packages.
There seems to be early evidence that there may be no immunity to the virus and it would be be surprising if a vaccine is developed any time soon, if at all. I would think that unless the country you live in has the virus contained, it's a massive risk to get back to business as usual too early.
Another concern is, who will want to visit a country that has persistent covid19?
