DALLAS (AP) — A Dallas emergency room sent a man with Ebola home last week, even though he told a nurse that he had been in disease-ravaged West Africa, and officials at the hospital are considering if they would have acted differently had the entire medical staff been aware.

The decision by Texas Health Presbyterian Hospital to release the patient, who had recently arrived from Liberia, could have put others at risk of exposure to Ebola before the man went back to the ER a couple of days later when his condition worsened.
