A number of medical experts, including Canada’s top doc, Dr. Theresa Tam, and American infectious disease specialist Dr. Anthony Fauci, have come under criticism for reversing their opinions about the use of non-surgical masks for the general public.
Those critics suggest that revising their opinions is an indication that these experts don’t know what they’re talking about.
I beg to differ. What it does mean is that we’ve learned more about COVID-19 than we knew in February. Those critics seem to forget or ignore the fact that this new virus is really less than six months old, and as with any virus, the more we learn, the more the experts will refine their policies.
