A health care worker who treated Thomas Eric Duncan for Ebola in Dallas has tested positive for the disease.
The individual was in full protective gear, including gown, gloves, mask and shield, when they provided care to Duncan during his second visit to Texas Presbyterian Hospital.
Duncan later died on October 8, despite treatment.
The worker is in stable condition, according to health officials who spoke Sunday. If the diagnosis is confirmed, it will be the first known case of the disease being transmitted in the United States.
Dr. Daniel Varga, of Texas Health Resources, said during a news conference Sunday that the health care worker reported a fever Friday night as part of a self-monitoring regimen required by the Atlanta-based Centers for Disease Control and Prevention. He said another person also remains in isolation, and the hospital has stopped accepting new emergency room patients.
