AIDs is Acquired Immunodeficiency Syndrome. It's a disease caused by HIV, which is the Human immunodeficiency virus. It causes your immune system to shut down. Nasty business. We became aware of it in the 1980s, and at the time it was primarily limited to men who engaged in homosexual activity, but it didn't stay that way. It's transmitted through bodily fluids, so sexual activity and drug use primarily.
Oh, you mean STDs. Sexually Transmitted Diseases. You'll also find them called STIs - Sexually Transmitted Infections. And don't worry about it, I'm not offended. Do you give them condoms? I mean, they're going to sleep with people anyway, and condoms will cut your STI rates a ton.
If I have questions, I'll ask. When I'm from, health is a public matter, and a serious one. I'm from a plague timeline. And I'm a journalist. So I believe in sharing information.
Then mostly all you have to look forward to is America pestering you for a while. But there's nothing like WWII again.
