But if this is a “GoF” virus could it be that it attenuates faster than a “normal” virus? Maybe that would explain why there are so many less lethal mutations so quickly. I doubt that would happen with a virus like measles but Coronavirus are known wimps.
I don’t know about any “GoF.” This virus came from bats, which are known reservoirs of any number of diseases that are deadly to humans (Ebola, Marburg, rabies, SARS, MERS). I do not know why these bat diseases are so deadly to humans, although I suspect that receptor differences between humans and bats account for some of it.
Anyway, I would hope that Covid-19 mutates itself into a less deadly form. I recall from my studies that there are a number of pathogens that were more deadly when they first emerged than they were once they had established themselves in the human population.
