If smallpox only affected humans, where did the first person contract it from? Is the virus related to other "pox"? Rickettsial, cow, chicken?

In brief: Virus

If they're all named with the same genus because they are related.
Chicken pox is a herpesvirus; the rule only works with the latin names. These viruses mutate and gene-swap so that's how they can 'jump species' and change from being zoonotic to affecting humans.
