Alicia Keys admits that her AIDS charity work in Africa is "frenzied" at times.

The 31-year-old singer is the co-founder of Keep a Child Alive, a non-profit organisation that provides medical treatment to children and families afflicted by HIV and AIDS in Africa.

To commemorate World AIDS Day, which takes place this Thursday, Alicia is airing her newest documentary on the subject Keep a Child Alive With Alicia Keys.

Filming in Africa for the second time was enlightening for Alicia.

"The first 2008 documentary entitled Alicia in Africa: Journey to the Motherland was about my experience there. This time we chose five Americans to come with me during the World Cup, so there's the juxtaposition of that frenzy and meeting the people we've been helping to get medication," Alicia explained to People magazine.

A few years back while filming the first documentary on the topic, Alicia was pregnant with Egypt Dean, her now 13-month-old son with her husband hip-hop producer Swizz Beatz.

"I remember thinking, My son, who isn't even born yet, is experiencing all these things through me.' It was very empowering," she recalled.

Egypt continues to bring great joy to Alicia and her husband.

She is elated to see her son progress.

"Egypt's walking!" Alicia gushed. "He's blowing my mind every second. Motherhood is the coolest."

Keep A Child Alive With Alicia Keys airs in the US on Showtime this Thursday December 1.
