PY - 2019 T2 - Pediatric Infectious Diseases: Essentials for Practice, 2e AB - Infectious mononucleosis is a clinical syndrome classically defined by the presence of fever, lymphadenopathy, pharyngitis, and fatigue. The illness was first recognized in the late nineteenth century and termed “glandular fever” or “Drusenfieber” by German physicians who noted its frequent occurrence in the context of family outbreaks.1,2 In a 1920 Johns Hopkins Medical Bulletin, Sprunt and Evans3 described six previously healthy young adults with a febrile illness similar to glandular fever and noted the presence of atypical lymphocytes in the peripheral blood smear. Because of the predominance of these unusual mononuclear cells, they termed the syndrome “infectious mononucleosis.” Twelve years later while investigating rheumatic disease, Paul and Bunnell4 serendipitously noted that the serum of patients with symptoms of infectious mononucleosis contained high titers of antibodies that agglutinated sheep red blood cells; thus the detection of these “heterophile antibodies” became the first laboratory marker available to diagnose the illness. The association of Epstein–Barr virus (EBV) with infectious mononucleosis followed in the late 1960s, when a laboratory technician working with specimens from patients with Burkitt’s lymphoma, a condition that had recently been shown to be associated with EBV, accidentally became infected and developed clinical infectious mononucleosis.5,6 SN - PB - McGraw-Hill Education CY - New York, NY Y2 - 2024/04/19 UR - accesspediatrics.mhmedical.com/content.aspx?aid=1157324115 ER -
