The National Institute of Health has started recruiting both patients and controls for their study that will "explore the clinical and biological phenotypes of post-infectious chronic fatigue syndrome (PI-ME/CFS)"
Full details can be found from the link below - they are looking for 186 participants in the study in three categories; those with ME/CFS that started after an infection, those who had Lyme disease, were treated, and returned to normal health and those who are healthy volunteers.
Participants will initially have a 2-5 day inpatient visit at the National Institutes of Health Clinical Center in Bethesda. Participants who are eligible will return for a further 5-10 day inpatient hospital visit, again at the National Institutes of Health Clinical Center.
