In honor of World AIDS Day, Alicia Keys sat down with Bono to discuss the battle against HIV/AIDS. The Keep a Child Alive co-founder and U2 frontman shared the advancements in medicine and science that are helping to end the epidemic.

“If you are able to be treated, then 96 percent of the time you will not spread the virus,” Alicia told George Stephanopoulos on “Good Morning America.” “It’s a tremendous breakthrough.”

Added Bono,

“This is why we can say this is the beginning of the end to AIDS. This is probably the greatest act of courage in my view since the second World War, what the U.S. has done here.”

Alicia was hopeful that soon AIDS will be eradicated.

“No matter who you are, we can all agree that we want an AIDS-free generation,” she said. “We have the possibility to be the generation, to have a legacy that we can say we created an AIDS-free generation.”
