AIDS expert Dr. Helene Gayle, president and chief executive of the charity CARE USA, has been named to chair the Presidential Advisory Council on HIV/AIDS, the U.S. government said on Monday.

Gayle, former head of AIDS research at the U.S. Centers for Disease Control and Prevention, will advise President Barack Obama on fighting the virus, which has infected an estimated 1 million Americans and 33 million people globally.

As we organize numerous ways to engage the American people in confronting the HIV epidemic in our country, the Presidential Advisory Council on HIV/AIDS will play a critical role in developing and implementing a national HIV/AIDS strategy, Obama said in a statement.

Gayle has also headed AIDS efforts at the Bill & Melinda Gates Foundation.
