History of International Chronic Fatigue Syndrome Awareness Day

CDC has developed a new Patient Toolkit to help people with ME/CFS, their families, and carers prepare and manage doctor visits. These resources describe the symptoms of ME/CFS in detail and provide essential information before, during, and after visiting a healthcare provider. People suffering with ME/CFS should use the new checklist to guide conversations with their doctor. A new chart can help in tracking of the medications and supplements. This toolkit has available in Spanish.

CDC also continues to showcase the experiences of people with ME/CFS through the Voice of the Patient series.

We recognize and support millions of people with ME/CFS and other chronic neurological and immune diseases by raising awareness and providing education.
