The Centers for Disease Control and Prevention says nearly 20 percent don't know they're infected. Right now, students from the Chicago area are part of the "FACE AIDS" (http://faceaids.org/) group that's biking across the U.S. from California to Massachusetts to raise money and awareness for AIDS research.
Along the way, they're giving presentations about FACE AIDS, the HIV/ AIDS pandemic, and the role of students in promoting social justice.
The riders spent July 28 and 29, 2012, in Chicago for a rest day. Gabi Greenberg from Highland Park, Sam Patel from Niles, and Augie Lindmark, who grew up in Deerfield, stopped by our ABC7 studio to tell us about their mission.
