A doctor who returned to a hospital after being treated for the Ebola virus last month did not contract a new case of the infectious disease, US health officials confirmed.

But he was admitted to the UMass Memorial Medical Center in Worcester, Massachusetts on Saturday with a cough and a low-grade fever. He was placed in isolation.
On Sunday, the Centers for Disease Control said lab results came up negative for Ebola.
"We are removing Dr Sacra from isolation, and his physicians are continuing routine care for his upper respiratory tract infection," the hospital said in a statement.
An American freelance cameraman working for NBC News who contracted the virus in Liberia was evacuated from Monrovia and is on his way to the United States to receive treatment.
Ashoka Mukpo, 33, is the fourth American to contract Ebola in Liberia and had worked on humanitarian projects in the west African country for several years.
