Long Covid and Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS) are closely related, confirms a study.

ME/CFS is a post-stressor fatigue condition that arises from multiple triggers. Of all people infected with SARS-CoV-2, about 10 per cent develop the chronic post-viral debilitating condition, long Covid.

Although long Covid is a heterogeneous condition, about half of cases have typical post-viral fatigue with onset and symptoms that are very similar to myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). However, a key question is whether these conditions are closely related.
