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
STD are just normal diseases which are extra hard to contract so they need intense contact of mucosa to even have a chance. Sex is just the most common one of this kind of contact.
doctors are quite certain that herpes virus is extremely old also. It arose around five thousand years ago, in the wake of vast Bronze Age migrations into Europe from the Steppe grasslands of Eurasia, and associated population booms that drove rates of transmission. https://www.cam.ac.uk/stories/ancientherpes
