The United States will announce nearly $1 billion in business deals, increase funding for peacekeeping and commit billions of dollars to expanding food and power programs in Africa during a summit this week, U.S. and development officials say.

U.S. officials said the Monday-Wednesday summit in Washington of nearly 50 African leaders hopes to showcase U.S. interest in the fast-growing region through a series of government-private partnership deals to boost trade and investment.

The spread of the deadly Ebola virus in Liberia, Guinea and Sierra Leone is also a reminder of the vast development needs that persist in some of the region's poorest countries, despite rapid economic growth and investment.
