Small pox was eliminated years ago, but does it or can it still be possible that it is somewhere in nature waiting to make a return?

The only known samples of smallpox are at the CDC and in a Russian bio bank. 

The top comment mentions an old sample in a freezer - worrying. More worrying though, is that chances are pretty good there’s a corpse somewhere in the permafrost in the north with preserved smallpox on it. Ice cores taken from ancient ice have yielded active viruses, though the paper I’m thinking of used amoeba as bait not human cells. 

If you find a frozen body don’t pick its scabs.
