This study compared symptoms and quality of life in people with ME/CFS, people with long COVID, and healthy controls in Australia. Both ME/CFS and long COVID patients experienced similar debilitating symptoms affecting memory, sleep, and physical function, and both groups had much lower quality of life scores than healthy people. The findings suggest that ME/CFS and long COVID are similarly serious illnesses that require comprehensive medical care.
This is the first Australian study directly comparing ME/CFS and long COVID symptom presentation and functional impact, providing evidence that both conditions cause similar, severe disability. The findings support advocacy for long COVID to be recognized as a serious multi-systemic illness with care needs comparable to ME/CFS, which may improve access to appropriate medical resources and multidisciplinary treatment for both patient populations.
This study does not establish causative mechanisms underlying either condition, nor does it prove that ME/CFS and long COVID are identical diseases—only that they share similar symptom profiles and functional consequences. The cross-sectional design cannot determine whether symptoms precede or follow illness onset, and the small sample sizes limit the generalizability of findings to broader populations.
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 →
