Chronic viruses are implicated in the etiopathogenesis of fibromyalgia syndrome. The increasing interest in research is derived from the clinical manifestations shared by both conditions, mainly the musculoskeletal pain and fatigue. However, in spite of intense research no viruses have unequivocally been identified as directly causing fibromyalgia. Exception may be the probable association between fibromyalgia and hepatitis C virus chronic infection. The authors present a literature review in order to approach the presumed associations or lack of associations between fibromyalgia and viral chronic infections. This compilation was done using Medline and Lilacs databases.
