Thomas Eric Duncan’s temperature spiked to 103 degrees during the hours of his initial visit to an emergency room, a fever that was flagged with an exclamation point in the hospital’s record-keeping system,

his medical records, obtained by the Associated Press, show. Duncan was the first Ebola case diagnosed in the U.S. Despite telling a nurse that he had recently been in Africa and displaying other symptoms that could indicate Ebola, the man who would become the only person to die so far from the disease in the U.S. underwent a battery of tests and was eventually sent home by Texas Health Presbyterian Hospital Dallas.
