It's too late. It's out there.
The best we can hope for now is to reduce our chances of getting it as much as we can but we can't avoid it completely. Stay healthy. Up our intake of natural antiviral foods. Keep out pets and livestock healthy. Distance.
But sooner or later this virus is going to recombine with another one that's not as "mild". I have a feeling it will be absolutely devastating to us, even if it doesn't actually infect humans, and there's a good chance of that.
We could be preparing for that eventuality, but that will take global political will we don't have and aren't going to have as well as looking beyond our immediate human selves. We're not so good at that either. We don't value other species outside what they do for us.
