An American cameraman freelancing for NBC News who tested positive for Ebola in Liberia remains in good spirits, his parents said. "He was more cheerful today," Ashoka Mukpo's father, Dr. Mitchell Levy, told "Today's" Tamron Hall on Friday. Mukpo, 33, was hired Tuesday to work with NBC News Chief Medical Editor and Correspondent Dr. Nancy Snyderman on assignment in the Liberian capital Monrovia, reporting on the Ebola outbreak. Mukpo came down with symptoms Wednesday and immediately quarantined himself before testing positive Thursday.
