Asking here as I'd like an answer backed up by some facts.
Theoretically can coronavirus mutate into something much worse? I've seen a few things being said about this, either:
- No, it will only mutate into something milder and eventually be like the common cold.
- Yes, it has the potential to mutate into something significantly worse.
- It has some limited potential to mutate and it might be worse, but only in a mild/moderate way.
The direction of travel with Alpha and Delta has been towards more immune escape and/or more transmissibility because they both give the virus an advantage in that they help the virus to spread.
Severity has no effect either way on the virus's ability to spread.
There's no advantage for the virus to become milder.
There's no advantage for the virus to become more severe.
(Because the illness part happens after spreading has already happened.)
Mutations are random and they only become dominant if they have an advantage over the current dominant strain.
So, the next variant is likely to be more transmissible and have more ability to evade immune escape than Omicron...
But the severity is a dice throw, a coin toss.
It could go either way.
It just depends what mutations that relate to severity happen to be on the variant that has enough transmissibility and immune escape to trounce Omicron.
There is absolutely no evidence anywhere that the SARS Cov2 virus is on a path of becoming intrinsically milder.
