International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (IACFS/ME)

Founded in 1990, the International Association for Chronic Fatigue Syndrome/Myalgic Encephalomyelitis (IACFS/ME) is the largest international organization of scientists, clinicians, and other professionals dedicated to the study, care, and treatment of individuals with CFS/ME, long COVID, fibromyalgia, and related conditions. Our mission is to promote, stimulate and coordinate the exchange of ideas related to these often disabling chronic medical conditions. In addition to organizing and participating in national and international scientific conferences, we publish a peer-reviewed journal (Fatigue: Biomedicine, Health, and Behavior), operate a monthly virtual journal club, issue timely position statements, and advise various groups, including the United States government. We are registered in the United States as a non-profit organization under section 501 (c) (3) of the Internal Revenue code of 1986.
