Where did STI/STDs come from? Since they are created via giving to someone who has already contracted it
So where did they originate from?
In: Biology
I mean it’s just the way these viruses evolved to propagate. The same way the common cold would propagate via coughing.
Maybe some ancient viruses only knew how to find a host via just lying on the ground until someone licked you up.
But then one virus evolved to infiltrate a saliva with its clones. So it began propagating much faster, completely displacing all of the “laying on the ground” type.
Some evolved to kill a host fast, while the others evolved to travel silently, making a host spread the virus to other hosts before dying. So yeah. Exchange of fluids during sex is kind of a good conduit for a virus to spread. And we only really thought of the way to help it in the last 100 years or so.
