This article explains that ME/CFS is a serious neurological and immune system disease, often triggered by infections like COVID-19, characterized by extreme fatigue lasting at least 6 months and a unique symptom called post-exertional malaise (PEM)—where even mild activity causes symptoms to worsen hours or days later. The authors stress that ME/CFS is a distinct medical condition that should not be confused with ordinary tiredness, and while there is no cure yet, treatment focuses on managing symptoms, addressing related circulation problems, and helping patients conserve energy through pacing.
