There is empirical evidence that social distancing and lockdowns were needed and worked.
(1) This disease, unlike other recent epidemics, has a high percentage of human-to-human airborne transmission from patients with no symptoms. New York City is a perfect example of the disaster that results from that.
(2) Vietnam is an example of lockdown isolation and quaratine working well. There have been no deaths and a only a few hundred cases in a country of 97 million with a porous border with China. Vietnam’s severe lockdown and quarantine was probably more severe than could be accomplished in western countries, but nevertheless, the evidence is instructive.
Keep this in mind as we contemplate re-opening for business and life.
