Myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) is a chronic, multi-system disease affecting millions of people. The syndrome is complex, debilitating and includes the hallmark symptom of post-exertional malaise with a wide spectrum of severity, from mild to very severe. Although the exact cause of ME/CFS is not known, it often follows an infectious-like illness.
