Long COVID: a new disease?
Mirofsky, Matias, Catalano, Hugo · Medicina · 2024
Quick Summary
This article discusses whether Long COVID should be considered a new disease and examines how medical systems can avoid overtreatment. The authors note that Long COVID shares similarities with other post-infection illnesses like ME/CFS and fibromyalgia, and they argue that careful, thoughtful medical care is important to prevent unnecessary treatments from making patients worse.
Why It Matters
This editorial is relevant to ME/CFS patients because it acknowledges the clinical overlap between Long COVID and ME/CFS, and emphasizes the importance of avoiding iatrogenic harm through excessive or inappropriate medical interventions—a key concern for both conditions. It supports the legitimacy of post-viral conditions and advocates for careful, evidence-based medical practice.
Observed Findings
- Long COVID presents with signs and symptoms persisting after acute SARS-CoV-2 infection with multiple terminologies and definitions across international literature.
- Post-infectious syndromes, myalgic encephalomyelitis, and fibromyalgia share clinical similarities with Long COVID.
- Quaternary prevention principles are applicable to Long COVID management to mitigate unnecessary medical interventionism.
Inferred Conclusions
- The classification of Long COVID as a new disease is complex and requires careful characterization to avoid definitional inconsistency.
- The overlap between Long COVID and established post-infectious conditions suggests shared pathophysiological mechanisms or clinical presentations.
- Medical systems should prioritize quaternary prevention to avoid harm from excessive or unnecessary interventions in Long COVID patients.
Remaining Questions
- What specific diagnostic criteria should define Long COVID to distinguish it from other post-infectious syndromes like ME/CFS?
- How prevalent is iatrogenic harm from unnecessary medical interventions in Long COVID populations?
- What are the mechanistic similarities and differences between Long COVID and ME/CFS?
- How should healthcare systems operationalize quaternary prevention in Long COVID management?
What This Study Does Not Prove
This editorial does not present original research data or establish causation, diagnostic criteria, or treatment efficacy. It does not prove that Long COVID is definitively a new disease or quantify the prevalence of overtreatment. As a conceptual analysis, it cannot validate specific case definitions or distinguish Long COVID from ME/CFS mechanistically.

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 →
