Infectious mononucleosis is a common viral infection caused by the Epstein-Barr virus (EBV) that mainly affects teenagers and young adults. Most people recover on their own within a few months, though severe fatigue can occur. This review explains the symptoms, how doctors diagnose it, and how to treat it—mainly through rest and avoiding strenuous activity.
This review is relevant to ME/CFS research because it explicitly identifies infectious mononucleosis as a documented risk factor for chronic fatigue syndrome, supporting the hypothesis that certain viral infections may trigger or precipitate post-viral fatigue syndromes. Understanding EBV infection and its potential to progress to ME/CFS-like illness may inform patient subtyping, prevention strategies, and mechanistic research.
This review does not establish the mechanisms by which EBV infection leads to ME/CFS, nor does it quantify the proportion of mononucleosis patients who develop chronic fatigue syndrome. It does not clarify whether ME/CFS after EBV represents true causation versus coincidental temporal association. The review is descriptive and does not present comparative or prospective data tracking mononucleosis patients into post-viral fatigue syndromes.
About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
