There are those who believe the actual occurrence of the disease is three times the known number. I see where recently in a plant in which there are some 3,000 employees, 400 or so tested positive for the disease but not one of them was symptomatic. 3x might be an underestimate. In NYC, apparently, 25% of the deaths were of nursing home residents. It does seem as if there is a serious need to protect those people (and those of similar health who are nevertheless at home) but to let everybody else go to work with those cautionary measures you mention. It really isn’t going to do most people any good to continue lockdowns indefinitely.
