Mass. Doctor Comes Down With Ebola

A Massachusetts man who has been diagnosed with Ebola in Liberia decided as a child that he wanted to become a missionary doctor.

Dr. Rick Sacra is the third U.S. aid worker sickened with Ebola. Sacra decided to return to Liberia after two others became ill with the deadly virus.

Sacra's brother, Doug, said he decided at the age of 10 that he wanted to take care of people who live in Third World countries.

Sacra has spent most of the last two decades living in Liberia, working for a missionary group. He works at the Family Health Center of Worcester when he is not in Liberia.

Sacra was not caring for Ebola patients, but was delivering babies at the missionary group's hospital.

The 51-year-old Sacra grew up in Wayland. He has a wife and three children.
