December 1 is World AIDS Day, a time when we remember the millions of lives lost to HIV/AIDS and the estimated 37 million people worldwide who are living with the disease.

For black America, the impact of HIV/AIDS is staggering.

According to the CDC, in 2010, black Americans represented more than one-third of all people living with HIV.

Black women also suffer higher rates of infection than other groups of women, with the same true for young black MSM (men who have sex with men) compared to other subgroups.

Despite the devastating toll it has taken, some important strides in reducing infections have been made.

In this video, we look at five ways HIV/AIDS impacts Black America in particular and how we can do our part to end the disease.
