Duncan began experiencing symptoms on September 24, 2014, and arrived at the Texas Health Presbyterian Hospital emergency room at 10:37 p.m. on September 25.[28] At 11:36 p.m., a triage nurse asked Duncan about his symptoms, and Duncan reported feeling "abdominal pain, dizziness, nausea and headache (new onset)."[28] The nurse recorded a fever of 100.1 °F (37.8 °C), but did not inquire as to his travel history as this was not triage protocol at the time.[28] At 12:05 a.m., Duncan was admitted into a treatment area room where the on-duty physician accessed the electronic health record (EHR). The physician noted nasal congestion, a runny nose, and abdominal tenderness. Duncan was given paracetamol (acetaminophen) at 1:24 a.m.[28] CT scan results came back noting "no acute disease" for the abdominal and pelvic areas and "unremarkable" for the head.[28] Lab results returned showing slightly low white blood cells, low platelets, increased creatinine, and elevated levels of the liver enzyme AST.[28][29] His temperature was noted at 103.0 °F (39.4 °C) at 3:02 a.m. and 101.2 °F (38.4 °C) at 3:32 a.m.
