No nothing to do with HIV and Covid mixing and becoming airborne HIV... just that to mutate a virus needs to reproduce and to have 30 or 40 mutations which all seem to be effective it's clearly had some time in some poor sod's body to do its thing. Normally someone would fight off covid or die of it within say 3 weeks, but people with HIV can have it for many months and maybe forever as their immune systems don't work well.
Yes agree, this was always a risk. But now it has happened.
What is different is that this isn't a slight variation from earlier strains, but seems to be a lot of “evolution” in one big step. This suggests a lot of variations have happened in one person who has had covid for a long time and then spread from that person around the community.
So this new variant has already spread to Europe, from a person who had visited Egypt but never been to South Africa. Looks unlikely it can be contained to Southern Africa now.
Good thing the pandemic is over, according to some learned twats on Geoexpat.
If the initial fears of this being sufficiently different to the original covid-19 virus to render vaccines significantly less effective come true then it is going to provoke a big policy re-think in developed nations.
