The New York Times ran an article on Monday based on interviews of medical experts on what needed to be in place to relax the lockdowns with reasonable safety. Its four requirements:
Hospitals in the state must be able to safely treat all patients requiring hospitalization, without resorting to crisis standards of care.
A state needs to be able to at least test everyone who has symptoms.
The state is able to conduct monitoring of confirmed cases and contacts.
There must be a sustained reduction in cases for at least 14 days.
Needless to say, the US is not even close to meeting these standards. From the close of the story:
Gregg Gonsalves, a professor of epidemiology and law at Yale, said: “I’d feel better if we had serological testing, and could preferentially allow those who are antibody positive and no longer infectious to return to work first. The point is, though, that we are nowhere even near accomplishing any of these criteria. Opening up before then will be met with a resurgence of the virus.”
