Supposedly that's why he was released from the UFC. Lots of blood in UFC fighting 
Dana White apparently wants him to come clean to the fans about his "lifestyle".
Doesn't Vince Goodrum have AIDS?
Doesn't sound like it.
http://www.digitaljournal.com/article/308417Pittsburgh - Former UFC middleweight contender Nate Marquardt has been indefinitely suspended by the Pennsylvania Athletic Commission (PAC) for failing to pass to his pre-fight medical exam despite a six-week notice.
PAC executive director Greg Sirb told media at a press conference - held late-evening June 26 - that both Marquardt and the UFC were notified six weeks ago that the fighter did not meet the necessary medical requirements to gain clearance. The commission gave Marquardt until before the weigh-ins for UFC Live 4 on June 25 to resolve the medical situation but was unable to, MMA Weekly reported.
“Nate has known for probably about a month and a half. He knew the situation. It was no surprise. Everybody (including the UFC) knew. Everybody’s known. I think everybody assumed he was going to be able to qualify,” Sirb said. "I thought he would qualify, I really did."
Due to medical privacy rules within the state of Pennsylvania, no further information was disclosed regarding the nature of why the fighter was not granted clearance to fight.
“We’ve known about it and we gave him every opportunity. The last report we got was three o’clock (Saturday). We gave him as much leeway as we could. Obviously we’ve got a live event, you’ve got to make the call. The UFC made the call when we said no he’s not going to meet it,” Sirb said in a MMA Weekly report.

www.mmajunkie.com) earlier today as to the exact timeline of events. Sirb said Marquardt, the commission and the UFC were all aware of the potential hurdles, but no one seemed overly concerned along the way.
In retrospect, Sirb said that may have been a mistake.
"We knew for some time," Sirb said. "I think everybody was under the assumption that he was going to be able to qualify. That may be a mistake on our part and on everybody's part. We shouldn't assume that.
"We tried as a commission. We had both out medical doctors ringside at weigh-ins, waiting for the results. We really tried to give him some leeway."
