Barack Obama

President Barack Obama plans to dramatically boost the U.S. effort to mitigate the Ebola outbreak in West Africa, including greater involvement of the U.S. military, the wall Street Journal has reported, quoting people familiar with the proposal.

The WSJ said Obama will unfurl the detail during a visit Tuesday to the Centers for Disease Control and Prevention in Atlanta.

Among the possible moves: sending additional portable hospitals, doctors and health-care experts, providing medical supplies and conducting training for health workers in Liberia and other countries.

Mr. Obama also is expected to urge Congress to approve the request he made last week for an additional $88 million to fund his proposal.

“There’s a lot that we’ve been putting toward this, but it is not sufficient,” Lisa Monaco, Mr. Obama’s counterterrorism adviser, said in an interview Sunday. “So the president has directed a more scaled-up response and that’s what you’re going to hear more about on Tuesday.”

Mr. Obama also plans to use a gathering of world leaders at the United Nations next week to seek commitments of funds, materials and health workers for a more robust international response, WSJ said.

The Ebola outbreak has infected at least 4,784 people as of Sept. 12, with 2,400 of them dying—a jump from 3,707 cases and 1,848 deaths as of Aug. 31. The true toll probably is much higher, the WHO says.

Liberia’s President Ellen Johnson Sirleaf last week sent a letter to Obama, asking for urgent assistance. Half of those the virus had killed were Liberians.
