WBZ TV 9/7/14: Mass. Doctor’s Condition Improving As He Battles Ebola. The Nebraska doctors treating the man who became infected with Ebola while working in Liberia say he is making progress, but it’s not yet clear if he will recover. Dr. Rick Sacra, who works at the Family Health Center in Worcester and lives in Holden, arrived at the Nebraska Medical Center on Friday for treatment in the hospital’s specialized 10-bed isolation unit. Two of the doctors treating him gave an update on his condition Sunday. Dr. Phil Smith says Sacra, 51, who grew up in Wayland, remains very tired, but his progress has been encouraging.
