What the study is about

CHIIME is a study of people who have myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). People who do not have this condition will also be enrolled. Volunteers will be observed and sampled over time to identify the long-terms biological drivers and impact of their condition. The overall goal is to understand the biological and physiological mechanisms that are driving this condition.
