I brought up covid in animals because the original poster mentioned the elimination of covid in the context of lockdowns.
The fact that covid can move between animal and human populations would seem to mean that lockdowns for the purpose of elimination will not work. Eventually humans would be reinfected from animals - mice, rats, pets, etc.
This has perhaps already happened. There is dna evidence that omicron evolved in mice and then jumped back into humans [0].
On the idea of lockdowns to eliminate the virus:
> The coronavirus’ ability to infect so many different animals, and to spread within some of those populations, is worrying news: It means there’s virtually no chance the world will ever be rid of this particularly destructive coronavirus, scientists said [1].
It would be a bummer to be locked down for months or years in an effort to eliminate the virus, and have to deal with the negative repercussions of lockdowns during and afterwards, only for everyone to become reinfected again from animals, and the whole thing start up again.
My apologies if I misunderstood your reply. You did seem to have a different angle than the original post. I just don't get it when people mention lockdowns to eliminate covid, when such a thing isn't possible.
I'm not sure what to say about your concern that animals can evolve a more dangerous virus. That seems like it can go either way. Animal evolved variants can also be less dangerous, like omicron, which is a good thing. Also locked down humans could be more vulnerable to more dangerous variants, their immune systems not having any prior exposure. How can anyone be so sure lockdowns always help?
