President Obama is geared up this World AIDS Day - and so are we. In a speech today, at George Washington University, Obama told attendees that we would "win this fight" against the HIV/AIDS pandemic. It's no small effort. And it's great news. In low-income countries, only half the people in need are receiving treatment.

"Winning the fight" though means designating more money to treatment (President Obama promised, today, an additional $50 million to combat HIV and AIDS globally through PEPFAR - the President's Emergency Plan for AIDS Relief) as well as calling on countries who have promised funds to the Global Fund to Fight AIDS, Tuberculosis & Malaria to meet their commitments.

What does this mean for those living with HIV and AIDS? It means two million more people will have access to treatment by 2013.

What can you do? Check out the facts below and see which ones resonate the most with you. Spread the facts on Twitter, Facebook, or face-to-face (wow!). If you do one thing today to help change the world, make it about helping those living with HIV/AIDS.
