The White House said on Thursday that it will not reschedule the U.S.-Africa summit slated for early next week due to the Ebola epidemic hitting Western Africa nations hard.

"At this point, there are no plans in place to alter the schedule in any way," spokesman Josh Earnest told reporters at a daily news briefing.

He said the U.S. Centers for Disease Control and Prevention ( CDC) "has concluded that there is no significant risk in the United States from the current Ebola outbreak."

The CDC on Thursday issued a warning advising American citizens against traveling to Guinea, Liberia and Sierra Leone.

The White House has invited leaders of African countries, except those from Zimbabwe, Sudan, Eritrea and the Central African Republic, for a summit in Washington D.C. on Aug. 4-6, the first of its kind in the United States.

The presidents of Sierra Leone and Liberia, however, have announced their absence from the gathering for a regional meeting instead to cope with Ebola.

"We certainly understand the decision that was made by some of these African leaders to not participate," Earnest said. "They obviously have some very pressing items of business to handle in their own countries."
