Dober thread Kaia Kupferschmidta na temo iskanja, v katero smer se bo razvijal virus Covid-19
One of the most important things I was looking for in reporting on #SARSCoV2 evolution was a way of making sense of all the virus variants, putting them in some framework. And one of the most useful things I found for that is this antigenic map.
It’s worth explaining a bit.
In its first year #SARSCoV2 spread in mostly naiive people and it made big jumps in infectiousness: D614G, Alpha, Delta.
“This virus has gone up three notches in effectively a year”, @edwardcholmes told me.
(Let’s debate another time whether this was surprising or expected.)
Think of it this way:
The virus spent the last year getting better at spreading in humans.
Now needs to get better at spreading in partly protected humans.
Several researchers told me that we are now at tipping point with evolutionary pressure moving more towards immune evasion.
