A TV news cameraman treated for Ebola was ready to go home Wednesday, the fifth patient transported from West Africa to recover at a U.S. hospital, as President Barack Obama brought together top aides and his new Ebola "czar" to co-ordinate a national response to the deadly disease.

Two nurses remain hospitalized after catching the virus from a Liberian man who came down with Ebola symptoms after arriving in the U.S. and died at a Dallas hospital. Because of their cases, the federal Centers for Disease Control and Prevention issued more stringent safety guidelines this week and is working with states to spread them to health care workers across the country.

"Recovering from Ebola is a truly humbling feeling," American video journalist Ashoka Mukpo said in a statement Tuesday from the Nebraska Medical Center. "Too many are not as fortunate and lucky as I've been. I'm very happy to be alive."

The virus has killed more than 4,500 people in West Africa, nearly all in Liberia, Sierra Leone and Guinea. Mukpo, got it while working in Liberia as a freelance cameraman for NBC and other media outlets. He has been at the Nebraska hospital since Oct. 6, the second Ebola patient treated there.

The hospital said that tests show Mukpo is now free of the virus and he would be allowed to leave its biocontainment unit Wednesday.

Debra Berry, the mother of Dallas nurse Amber Vinson, said Tuesday her daughter is "doing OK, just trying to get stronger" while being treated at Emory University Hospital in Atlanta. Fellow Dallas nurse Nina Pham's condition has been upgraded from fair to good at the National Institutes of Health outside Washington.

At the White House, Obama was meeting with his new Ebola co-ordinator Ron Klain and top aides Wednesday.

Under heavy criticism for the government's handling of the first Ebola case diagnosed within the U.S., Obama reached for help last week from Ron Klain, a veteran political operator. Klain will co-ordinate the array of federal agencies dealing with Ebola in the U.S. and helping to tackle the crisis in West Africa.

The Obama administration has resisted pressure to ban travel from the Ebola-stricken countries but was tightening rules in an effort to ensure that all arrivals from the three nations are screened for the disease.

Under restrictions taking effect Wednesday, air travellers from Liberia, Sierra Leone and Guinea must enter the United States through one of five airports doing special screenings and fever checks. A handful of people had been arriving at other airports and missing the checks.

A total of 562 air travellers have been checked in the screenings that started Oct. 11 at New York's Kennedy airport and expanded to four others last week, Homeland Security officials said. Four were taken from Washington's Dulles airport to a local hospital. None had Ebola.

The other airports are Newark's Liberty, Chicago's O'Hare and Atlanta's Hartsfield-Jackson.
