STD's, I've always wondered.... Options

Where do they come from?

People have said that they come from having alot of sex, but that's probably the most vague answer there is.

They just magically appear after you've done a certain number of people?

Exactly how to they come to be?

I taught from a curriculum that taught STI & HIV.

Mainly, it was changed to STI because DISEASE connotes that there is no treatment and no cure. INFECTION most people think that there can be medicine to "fix" it. Partly, it to convey the actual symptomatic parts of the infection but also, they hope the new term will encourage people to get help.

STI isn't much different than the cold virus. They exist. They are just different forms of a similar being. You can simply think of it like. Like Gigi said, these viruses and bacteria underwent some mutations and through that, evolved the best system to ensure it's survival.

HIV is a mutation of the chimp virus SIV. Whether it's from ... fornicating with a chimp or the tribal traditions of eating chimp brain (theories that SIV is prominent in the brain lining of a monkey) or species to species cross blood transmission. Whatever it was, people think that the SIV virus from chimps got transmitted to humans. The lucky SIV virus with the right genetics was able to procreate in humans and therefore, became HIV. (Still kinda the working theory)
