This review examined whether bacteria that stay dormant (inactive) in the body after an infection could cause chronic fatigue syndrome symptoms. The researchers looked at scientific evidence and found no proof that dormant bacteria cause the ongoing fatigue and other symptoms people experience after bacterial infections. The study suggests that psychological trauma and unknown causes may play a role in post-infection fatigue, rather than persistent bacterial infection.
This research directly challenges a common misconception that persistent symptoms after bacterial infections—especially Lyme disease—are caused by dormant bacteria in the body. For ME/CFS patients, this clarifies that if post-infectious fatigue is occurring, the underlying cause likely involves different mechanisms than persistent infection, potentially redirecting clinical investigation and treatment approaches.
This study does not identify what actually causes post-bacterial infection chronic fatigue syndrome; it only rules out dormant bacteria as the primary mechanism. It does not establish that unknown microorganisms, immune dysregulation, or other pathophysiological mechanisms are responsible. The review also cannot definitively determine the role of psychological trauma without additional empirical research.
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 →
