"Bug Chasers" as they are called are mostly homoloveual people seeking STDs like HIV and spreading it around to as many people as possible. These people are the scum of the earth and should be euthanized. It is illegal to willingly spread a virus without the other's consent or knowledge. I've read some stories about it, and it's absolutely horrifying what some people do, I remember reading one story where the writer states that he must've spread HIV to over 500 unknowing loveual partners, just for the sake of pleasing our lord Nurgle spreading it.
This is where most of the scare from STDs come from, because people are being starfishs, by spreading it to another's starfish. There used to be huge parties where the main focus of it was just to contract as many STDs as possible, and these parties probably still exist. A lot of homoloveual males may have HIV without knowing it, and they spread it further and further, realizing they forgeted up only when doctors refuse their blood and when they have to call all of their previous partners.
It's sad to say, but contracting STDs is a lot easier when you're gay, just because people are disgusting.
