A New York doctor who was diagnosed with Ebola after working with patients in West Africa will be released on Tuesday from a hospital where he has been treated for the disease, the hospital said. Dr. Craig Spencer, 33, had been held in isolation in Bellevue Hospital Center since he was diagnosed with Ebola on Oct. 23, after working with patients in Guinea with Médecins Sans Frontières. Spencer will join Mayor Bill de Blasio and other city officials and Bellevue staff at a news conference on Tuesday morning, the hospital said. Spencer is expected to make a statement but not take questions, the hospital said.
