This is really fascinating. It would seem that the bulk of Covid-19 cases are asymptomatic, 80% in this case. When asymptomatic people are out and about in society, feeling well, going about their business, they are unknowingly (potentially) spreading virus among the people they have prolonged contact with. Hence masks for all being a viable solution until there is a treatment protocol, or vaccine of course, for this new illness. I also read recently that many in the medical and science industry believe that Covid cycled widely around the US during our flu season this year and many may have unknowingly had it already. I am certainly following the stories of this tenacious virus to see how it pans out. My hope is that as it mutates through the months, it becomes less potent and less contagious.
