It seems I read a few years back that the more people catch a virus, the more likely it is to adapt. So, for example, even if the virus is more virulent in Asians now, (and the one study with the 8 samples is pretty weak, maybe there are others out there now), the more it infects people of other races, the more likely it is to adapt. Of course, after a while, it can become less virulent too, but Im not seeing that so far!
I think we really need to back off on the assumption that this was “targeted” by race. The white guy in Britain seems to be spreading this just fine.
