A male college freshman is seen at the college health service complaining of general fatigue, a sore throat, and swollen lymph nodes in his neck. A throat culture is done, blood is drawn for hematology studies and a rapid MonoSlide test is performed. Hematology results show a normal hemoglobin value and a slight inrease in the white cell count, with many large, reactive lymphocytes seen in the differential. A rapid strep test is negative, but a second swab is cultured on sheep blood agar and incubated, with the result to be read in 18 hours. The result from the MonoSlide test is positive. From these findings, what is the probable diagnosis for this patient?
