I think they need more testing for the COVID 19antibodies. When people are identified already having COVID 19 then they can resume going back to work and we can slowly start opening up the country again. Here in California they are thinking that maybe the virus occurred earlier leading to herd immunity do to the low infection death rate in the state. Here is a paragraph from the national review.
One less-mentioned hypothesis is that California, as a front-line state, may have rather rapidly developed a greater level of herd immunity than other states, given that hints, anecdotes, and some official indications from both China and Italy that, again, the virus may well have been spreading abroad far earlier than the first recorded case in the U.S. "and likely from the coasts inward.
As with testing for the virus I believe it's just as important to see who has already had the virus.
