How could these statistics be true?

When it comes to health statistics such as HIV and Cancer , does the media over-exaggerate things to scare people ? Like I read in a brochure how EVERYDAY just in the U.S alone , 6,000 young people contract HIV , how accurate is this ? 6,000 seems like an awful lot . I am trying to visualize 6,000 people in a baseball field , damn thats a lot of people ! 6,000 EVERYDAY!
