Although the term "chronic Lyme" was once used by Steere and others to define persistent complications following acute Lyme disease, various Lyme advocacy organizations and a dissident group of doctors called the International Lyme and Associated Diseases Society (ILADS) have redefined the term to describe a wide range of symptoms, mostly in patients who have no evidence of Lyme disease. Steere and his colleagues said that even patients with a positive serology for "Borrelia" infection and with symptoms resembling those of CFS or fibromyalgia, would not be helped by further antibiotics.
