H.I.V. POSITIVE
That's the human immunodeficiency virus.
Transmission is primarily through unprotected sex with an HIV positive individual.
Earvin "Magic" Johnson, legendary point guard for the Lakers NBA team, was HIV positive.
When another player was asked whether he was worried about playing a game with Magic, the player responded, "We're just playing basketball. We're not out here to have unprotected sex with Magic."
