Apparently our DNA is literally encoded with lots of viruses, as they've evolved to become utterly harmless to people. Our bodies are loaded with various bacteria and viruses that have evolved a symbiotic relationship to the point where we'd die without them, and they can't live without us.

I seriously doubt they started out that way.

Smallpox (around since about 500 BC or earlier near as we can tel), still had a 35% lethality rate until it was eradicated in the 70’s though an extensive vaccination campaign.

Diseases can be severely lethal far longer than you or human memory can survive.
