My understanding is that the virus may have shifted a bit to be a tad be less lethal. This triggered my first panic button a few months ago. My limited understanding is that further drift may occur as cases with longer incubation periods infect more people than the sub-strains with shorter incubation periods.
I agree that the worst thing that could now happen would be a virus shift to easier transmission but for now that has not happened and it may not happen. However even if there is an extremely remote chance of such a shift happening (and there is) appropriate resources need to be applied to ensure that it doesn't. So far the global response has been a blundering exercise in talk fests and bureaucracy gone wrong so we can but wait and see what happens next.
