Every 10 minutes, someone in the U.S. contracts HIV. Half are black.

On Tuesday, FRONTLINE will air ENDGAME: AIDS in Black America, a groundbreaking two-hour exploration of one of the country’s most urgent, preventable health crises.

Renata Simone, who produced, directed and wrote the film, and Dr. Robert Fullilove, a professor of clinical sociomedical studies at Columbia University, were on NPR’s Fresh Air with Terry Gross today to discuss the political, social and cultural factors that caused the epidemic to spread within the African American community, and why prevention has yet to work.

“We still have a long way to go in policy terms,” Simone tells Gross. “What I tried to do in the film is help a general audience see that this is an epidemic not just of drug users and people who are sex workers. This is an epidemic that affects people who make you think, ‘But for the grace of God, there go I.'”
