The variant should provoke symptoms faster than the Delta-4, and respiratory stress happen fast at the onset.
No word on how the models were designed. No word on how they know there will even be a "deadly" variant, and how it will even act if it doesn't even exist right now.
I'm flabbergasted.
The only silver-lining I can see from this prediction, is that if it's deadlier and faster to show symptoms, then it will be easier to contain and accelerate the end of the scamdemic, as the big problem of the 'rona is the relative silence allowing "asymptomatic spread".
Do these models "know" that evolution for a virus invariably moves in the direction of lower lethality? Becoming more lethal is not a successful evolutionary survival strategy for a virus that depends on its host for replication.
Depends. Becoming more lethal in a context where lower lethality already led to a part of the elderly dying but not the active spreaders is a non-issue.
Lethality can increase while keeping under a threshold to allow spreading among the active, young population, to the older population who has more of a chance to die.
