Wayland Town Crier 1/12/15: Massachusetts doctor who beat Ebola heading back to Liberia. The Massachusetts doctor who beat Ebola plans to return to Liberia, where he contracted the deadly virus, in order to help overworked colleagues in the missionary hospital where he has worked for years. Dr. Rick Sacra, 52, a Wayland native who now lives in Holden, said Monday he won’t be working directly with Ebola patients but might be asked to help from time to time, since doctors say he’s now immune. He departs Thursday.
