===Differential diagnosis===
About 10% of people who present a clinical picture of infectious mononucleosis do not have an acute Epstein–Barr-virus infection.<ref name=Bravender2010>{{cite journal|last=Bravender|first=T|title=Epstein-Barr virus, cytomegalovirus, and infectious mononucleosis|journal=Adolescent Medicine: State of the Art Reviews|date=August 2010|volume=21|issue=2|pages=251–64, ix|pmid=21047028}}</ref> A differential diagnosis of acute infectious mononucleosis needs to take into consideration [[Human cytomegalovirus|acute cytomegalovirus infection]] and ''[[Toxoplasma gondii]]'' infections. Because their management is much the same, it is not always helpful–or possible–to distinguish between Epstein–Barr-virus mononucleosis and cytomegalovirus infection. However, in pregnant women, differentiation of mononucleosis from [[toxoplasmosis]] is important, since it is associated with significant consequences for the [[fetus]].<ref name=Ebell2004/>

Acute [[HIV infection]] can mimic signs similar to those of infectious mononucleosis, and tests should be performed for pregnant women for the same reason as toxoplasmosis.<ref name=Ebell2004/>

People with infectious mononucleosis are sometimes misdiagnosed with a [[streptococcal pharyngitis]] (because of the symptoms of fever, [[pharyngitis]] and [[Lymphadenopathy|adenopathy]]) and are given antibiotics such as [[ampicillin]] or [[amoxicillin]] as treatment.<ref>{{cite web|url= https://www.lecturio.com/concepts/mononucleosis/|title= Mononucleosis|website= The Lecturio Medical Concept Library|date= 4 August 2020|access-date= 11 August 2021|archive-date= 11 August 2021|archive-url= https://web.archive.org/web/20210811080259/https://www.lecturio.com/concepts/mononucleosis/|url-status= live}}</ref>

Other conditions from which to distinguish infectious mononucleosis include [[leukemia]], [[tonsillitis]], [[diphtheria]], [[common cold]] and [[influenza]] (flu).<ref name=Longmore2007/>
