A new NIH-funded study found a sharp rise in ME/CFS cases. Researchers discovered that 4.5% of post-COVID patients met ME/CFS criteria. Only 0.6% of uninfected people met the same criteria.
ME/CFS, or Myalgic Encephalomyelitis Chronic Fatigue Syndrome, is a chronic illness. It often develops after infections and affects the nervous and immune systems. The condition causes severe fatigue that worsens after activity, called post-exertional malaise. Other symptoms include brain fog, dizziness, headaches, muscle weakness, and sleep problems.
