The E.R. physiciаn nоticed а rооm full of pаtients when he walked into the hospital for the evening shift. One patient was visibly sick and was the first patient to be seen by the physician. The patient was a 25 y/o BM who had just returned from Kenya where he had been on a Peace Corp mission trip. He told the doctor that he started feeling ill after he got on the plane to fly back to the U.S. He arrived home 3 days ago but got progressively worse. He said he was fatigued, had no appetite (anorexia) and nauseated. He had vomited several times that morning. On physical examination, the doctor noticed the patient had jaundice of the sclera of his eyes. The doctor ordered a CBC, routine urinalysis and chemistry panel. The first procedure to be completed by the laboratory staff was the urinalysis and it was called STAT to the physician. The U.A. results included: Color: Light Brown Glucose: Negative Blood: Negative Specific gravity: 1.030 Protein: Negative Bilirubin: Positive Urobilinogen: 8.0 Ehrlich Units Leukocyte esterase: Negative Nitrite: Negative Ketones: 1+ The microscopic urinalysis was essentially normal. From these findings what is the most likely explanation for this person’s nausea and jaundice? (L-3)
