Cause Celeb: Debra Messing Partners With Population Services International to Support HIV Prevention

Debra Messing is a celeb with a cause: On page 112 of the new May InStyle, the actress takes us on the road with her as she journeys to Zambia with Population Services International (PSI), a nonprofit that saves lives around the world by providing small but highly effective health interventions to battle the spread of HIV. "I lost my acting teacher, Paul Walker, to AIDS in 1993," Messing says in the issue. "It's a cause that runs deep for me." While in the country, she even had a public HIV test while there to prove that it's important for everyone to get one. "Each day in Zambia was an emotional assault—you come face-to-face with people who are ill when they don't have to be," Messing says. "That's where PSI comes in: It brings tools like HIV testing, counseling, condoms, and medicine to communities that need them." And there are ways you can help, too: Head to the Facebook page of Make (+) More Positive, "like" it, and PSI will donate one HIV test kit to an area in need. Follow @PSIimpact on Twitter for updates, and head to psi.org to donate—just $30 can buy the needed supplies to give one person a year of healthy life.
