Via AP:

A Texas health care worker who provided hospital care for an Ebola patient who later died has tested positive for the virus, health officials said Sunday in a statement. If the preliminary diagnosis is confirmed, it would be the first known case of the disease being contracted or transmitted in the U.S.

A statement posted on the Texas Department of State Health Service’s website said “confirmatory testing will be conducted by the Centers for Disease Control and Prevention in Atlanta.”
