there are over 200 variants of "the common cold"
there are also 22 variants of Covid
Each one less severe than the last
According to your previous post, viruses become less severe with each mutation. I mostly agree with this, although it is likely there are exceptions. The scientific theory is if a virus kills its host, it dies. So, for a virus to survive, as it mutates it often becomes less severe but also more infectious/contagious.
My point has to do with folks who say
COVID is just another rhinovirus. If this is so, why is COVID more severe than a cold? It is my guess this is because it is not another cold virus.
