Obviously if there is a mutation, it will only affect one of them (or some by chance), but the others have no reason to mutate. For a strain to spread, it has to be more contagious than the others, but that doesn't kill them all at once. There is no reason for remote areas to see a drop in virulence in a coordinated fashion ...
Uh not sure to understand everything ...
I was just talking about the "global" virulence of the virus which could be weakened by the outside temperatures ...
People who are currently diagnosed positive were most likely infected during the heatwave of early / mid August ... and as hospitalizations do not "follow" (so much the better) ... there is necessarily a factor that makes the virus is less "nasty" ...
I'm just asking the question if it could be the outside temperature. That's all.
I don't see how the temperature influences the virus itself, which is a very simple set of molecules (DNA surrounded by a few proteins). Temperature only affects the efficiency with which it propagates (droplets evaporate faster, and people remain less confined).
Possibly it can also act on the immunological resistance capacities of individuals, but it is not a priori the virus which changes (it is not "complicated" enough to feel the temperature like a multicellular animal which "would be hot" by example!) n
