This case report describes a 17-year-old girl who experienced severe fatigue caused by Epstein-Barr virus (EBV) infection, commonly known as infectious mononucleosis. The authors highlight that fatigue in young people can come from many different causes, not just COVID-19, and that it's important to identify the correct cause. Notably, about 13.5% of people who have EBV infection go on to develop ME/CFS, making proper diagnosis essential.
This study reminds clinicians that ME/CFS can develop after EBV infection, and proper identification of the triggering infection is crucial for patient care. For ME/CFS researchers, it reinforces the importance of studying post-viral mechanisms, particularly EBV as a potential disease trigger. Understanding the link between acute viral infections and ME/CFS development may eventually lead to earlier intervention strategies.
This single case report cannot establish causal mechanisms linking EBV to ME/CFS development, nor can it quantify risk factors or predict which patients will progress to chronic disease. The 13.5% figure cited is from literature review, not primary data collection in this case. Case reports are anecdotal and do not prove that EBV infection causes ME/CFS in the general population.
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 →
