This paper suggests that viral infections may damage the body's ability to handle stress at the cellular level, making tissues more vulnerable to injury. Rather than looking for one specific virus causing ME/CFS, the authors propose that ME/CFS might result from a general, nonspecific cellular damage response that occurs after many types of viral infections. Understanding this mechanism could open new treatment possibilities for conditions that have not responded well to existing therapies.
This hypothesis challenges the conventional search for a single causative virus in ME/CFS and instead proposes a unifying mechanism—deficient cellular stress response—that could apply to post-viral conditions broadly. If validated, this framework could redirect research toward restoring stress response pathways and developing therapies targeting cellular protection rather than viral elimination alone.
This is a theoretical review article and does not present original experimental data, patient studies, or direct evidence that ME/CFS is caused by impaired stress response. It does not prove causation or demonstrate that this mechanism applies specifically to ME/CFS patients, nor does it provide evidence that stress response dysfunction is measurable or reversible in affected individuals.
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 →
