Plainfield, IA (CNN) - Saturday is World AIDS Day and a lot of progress has been made slowing down the epidemic.
But just this week, the Centers for Disease Control and Prevention reported that almost a quarter of new HIV cases are seen in young people, and more than half of them don't know they're infected.
One young man in Iowa knew his HIV status, but didn't reveal he was HIV positive to his sexual partner.
After a one-time encounter, Nick Rhoades found himself charged with criminal transmission of HIV because of his silence.
His case is now before the Iowa Supreme Court because he trying to get his conviction overturned.
"I actually was not guilty of what I pleaded guilty to. So I think that justice needs to be served and that's why we're fighting for a post conviction release situation I would love to have this expunged from my record. If I'm not guilty of a crime I don't want to live with that scarlet letter for the rest of my life and so what we're hoping for, pie in the sky, is having it overturned but I don't know what's going to happen but I know it's worth fighting for and at the very least I'll be able to get another trial," said Rhoades.
