What is recovered?
I think there might be at least two types of recovered.
Type One as in Boris Johnson, you go in to hospital as a suspect covid-19 person, they do a test, you are positive, they keep you in for a few days as long as you do not go down hill they let you go, after some mild interventions.
Type Two as in, you are put in an induced coma and connected to a ventilator, half the people will die, the other half are taken off the ventilator put in a bed with an oxygen mask but these people with suffer ongoing troubles, such that they may never walk or work again.
