The United States has donated $56 million to help the World Food Program's efforts to fight HIV and AIDS in Ethiopia.

The U.N. agency said Tuesday the donation will allow it to reach an additional 375,000 people over five years, providing a boost in nutrition that increases the success of antiretroviral treatments. That is more than double the number of people the agency says it reached between 2008 and 2010.

The money from the U.S. anti-AIDS initiative, PEPFAR, will allow the World Food Program to expand its programs for people living with HIV outside of Ethiopia's urban areas.

The agency says it will work in the country's least developed regions, including Afar, Benishangul Gumuz, Somali and Gambella.
