There are no reported cases of Ebola in the U.S. But Massachusetts General Hospital in Boston said late Tuesday that it had admitted a patient for evaluation.
The White House is running a federal preparedness effort that includes equipping more labs to test for Ebola and completing early clinical trials for the first vaccine to treat the disease.
White House Press Secretary Josh Earnest said the White House remains concerned the money may not make it into the year-end spending bill being crafted in Congress.
Earnest said officials have been in close touch with lawmakers to lobby for the funding and that the White House considered Ebola a "top national security threat." Still, it was unclear how far the White House is willing to go to fight for the funding. Earnest said Tuesday that the president was not prepared to issue a veto threat over the issue.
The vaccine could enter the testing phase in West Africa soon.
With the new treatment facilities in place, more than 80% of travelers from West Africa will enter the U.S. within 200 miles of a treatment center, officials said. Travelers who show signs of Ebola infection will be transported to these hospitals by ambulance.
The hospitals are in California, Georgia, Illinois, Maryland, Minnesota, Nebraska, New Jersey, New York, Pennsylvania, Texas, Virginia, Wisconsin and Washington, D.C.
