President Barack Obama is expected to announce plans Wednesday to withdraw most of the American troops assigned to battle the Ebola outbreak in West Africa, and to declare that the U.S. military effort has been successful.
The U.S. military is expected to pull out most of the 1,300 American forces currently working in Liberia and Senegal, where officials believe the crisis has largely been contained.
Just 100 will remain in West Africa after April 30, working with Liberia's military, regional partners and U.S. civilians to continue fighting Ebola.
The worst Ebola outbreak in world history has killed almost 9,000 people.
The World Health Organization, the U.N. agency, warns that challenges remain in bringing cases down to zero. The outbreak is expected to cost the three most affected countries, Liberia, Sierra Leone and Guinea, at least $1.6 billion in lost economic growth this year.
