Background: Prevalence studies on Chronic Fatigue Syndrome (CFS) are rare. Because of the similarity in symptoms, the prevalence of Primary Fibromyalgia Syndrome (PFS) was investigated at the same time.
Objectives: To determine the prevalence of CFS and PFS as recognized by GPs in The Netherlands and to inform them of the existence of CFS.
Methods: A postal questionnaire was sent to all GPs.
Results: The questionnaire was returned by 60% of the GPs. Seventy-three per cent reported one or more CFS patients and 83% one or more PFS patients in their practice.
Conclusion: The estimated prevalence of CFS as recognized by GPs of 112 (PFS 157) patients per 100,000 is a minimum estimate.
