As long as we identify and protect those at risk (visible symptoms/elderly/pre existing medical issues) the rest of the population can go about its business. Herd immunity will take care of the virus, as its done for millions of years. Jamie On Thu., Apr. 30, 2020, 20:55 Stephen Shaw, <srshaw@dal.ca> wrote: > Hi Nancy, > Strange?=E2=80=94 no.
