Breaking News: First U.S. Ebola Patient Dies In Texas.

Thomas Eric Duncan, the man with Ebola who traveled to the United States from Liberia, died Wednesday morning at Texas Health Presbyterian Hospital in Dallas, the hospital said.

He had been in critical condition after being diagnosed with the virus in mid-September. People who have had contact with him are being monitored

for symptoms.

It has just been a little over a week since Duncan began receiving treatment for the virus, and those days have spelled an "enormous test of our health system," said Dr. David Lakey, the commissioner of the Texas Department of State Health Services.

"For one family it has been far more personal," he said in a statement. "Today they lost a dear member of their family. They have our sincere condolences, and we are keeping them in our thoughts."

He vowed that health care workers will continue to try to stop the spread of the virus "and protect people from this threat."
