In this interview clip, actress Jennie Garth, who plays the character of Sarah in the Lifetime Original Movie “Girl, Positive,” talks about the lack of discussion of HIV/AIDS. The Lifetime Original Movie “Girl, Positive” is the story of Rachel (Desperate Housewives’ Andrea Bowen), a high school senior, whose world is thrown into a tailspin when she tests positive for HIV. In trying to deal with this frightening news, Rachel finds an unlikely ally: a substitute teacher (Jennie Garth) who has secretly lived with HIV for years. Unfortunately, secrets have a way of getting out — and both women soon learn that gossip, like disease, can spread swiftly. “Girl, Positive” premieres Monday, June 25, at 9PM ET/PT on Lifetime.
