WASHINGTON (AP) — Ashley Judd says education and prevention is the best way to combat AIDS and HIV, which disproportionately affect women and girls and prey upon the vulnerable and less fortunate.

Speaking about her new documentary film, "India's Hidden Plague," in an interview broadcast Sunday on ABC's "This Week," the actress said it costs just $10 to educate a person about the risks and protect them for an entire year.

The actress met with HIV/AIDS orphans in India while making the film, including two sisters, ages 9 and 12, whose parents died in quick succession after their father infected their mother with the disease.

"It's very real and it's real stories and real heartache and also real opportunity to focus on a solution that is very cost effective and has an extraordinarily meaningful impact in the lives of young people," Judd said. In a previous documentary film, "Confronting the Pandemic," Judd and actress Salma Hayek traveled to Central America to look at AIDS prevention there.

"India's Hidden Plague" is set to premiere Nov. 30 on the National Geographic Channel.
