"Even those without long Covid could benefit from such research, as symptoms noted in long Covid patients show many similarities to those seen in chronic and viral-related illnesses including myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) – another disease that has been dismissed as “psychological” for decades. Just because we have not yet identified a biomarker for long Covid does not mean biomarkers do not exist. We just need to look harder."
