In March during the wuhan pandemic in the U. S., many old people died in the that first nursing home in Washington state while no crewmen among those infected on the ship Roosevelt died, which provided the profile for the wuhan, dangerous only to the elderly and/or with co-morbidities, so the way forward is as it always was, protect the elderly and the chronically ill while everyone else carries on as usual. We may have more to go with the wuhan, but we certainly know who is most vulnerable.
