“…Infectious agents such as Yersinia enterocolitica , Brucella , Bartonella henselae , Entamoeba histolytica , Mycobacterium szulgai , and Toxoplasma gondii were implicated but subsequent studies failed to support these findings [ 7 , 10 ]. Viruses such as Epstein-Barr virus, herpes virus, cytomegalovirus, parvovirus, paramyxovirus, parainfluenza virus, Rubella, hepatitis-B, human immunodeficiency virus (HIV), human T-lymphotropic virus type-1 (HTLV-1), and the Dengue virus have all been suggested as probable etiologies of KFD, but never convincingly demonstrated [ 7 ]. On the other hand, some authors hypothesized that KFD may reflect a self-limited autoimmune condition induced by virus-infected transformed lymphocytes.…”
