Letter to the Editor of Metabolites explaining the estimate of 65 million people with ME/CFS worldwide

Back in January 2020, Germain et al published a metabolomics paper in Metabolites stating:

The latest worldwide prevalence rate projects that over 65 million patients suffer from myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS)…

This 65 million people with ME/CFS figure has brought about some attention resulting in this letter to the Editor. Importantly, this letter brings several more supporting references beyond the initial Valdez et al publication. The key takeaway from the letter is that the prevalence of ME/CFS is likely much greater than the oft-cited figure of “20 million worldwide.”
