Thomas Eric Duncan, the man from Liberia who was the first diagnosed case of Ebola in the United States, has died. He was 42.

It is with profound sadness and heartfelt disappointment that we must inform you of the death of Thomas Eric Duncan this morning at 7:51 a.m. Mr. Duncan succumbed to an insidious disease, Ebola. He fought courageously in this battle. Our professionals, the doctors and nurses in the unit, as well as the entire Texas Health Presbyterian Hospital Dallas community, are also grieving his passing. We have offered the family our support and condolences at this difficult time.

Duncan, who grew up in Liberia, came to the United States to attend his son's high school graduation. He became the country's first diagnosed case a week later.
