At a press conference in Atlanta, the director of the U.S. Centers for Disease Control and Prevention, Thomas Frieden, said that the patient came from Liberia and was in Texas visiting family.

Ebola has killed more than 3,000 people across West Africa and infected several Americans who have traveled to the region.
