By LUIS MARTINEZ • 5 min read Email this article WASHINGTON, D.C. -- The U.S. military is ending its Ebola relief mission in West Africa, with the last American troops scheduled to leave Liberia by April 30. The announcement comes as Ebola infection rates have been reduced dramatically in recent months. In September, President Obama announced that American military personnel would be deployed to Liberia to help stem the Ebola epidemic in West Africa. The military personnel participating in Operation United Assistance did not treat Ebola patients, but helped build the infrastructure and facilities to treat them.
