Data were tabulated on Bioestat 5.0 generating tables, and descriptive analysis and Pearson chi-square test were performed at a significance level of 5% (p&lt;0.05). <strong><em>Results:</em></strong> there were 1,351 (7.87%) cases of leprosy relapse in the state of Bahia, with prevalence in males (61.1%), pardos (57.7%) and with age greater than or equal to 15 years (99.6%). The dimorphic clinical form, the zero degree of incapacity and the operational classification for MB were the most frequent, using PCT/MB/12 in 82.1% of cases. <strong><em>Conclusion:</em></strong> there is low effectiveness in the control of leprosy in the state of Bahia, since there was a relatively high prevalence of cases of relapse in the period under study. <strong><em>Descriptors</em></strong><strong>:</strong> Leprosy; Relapse; Epidemiology; Neglected Diseases; <em>Mycobacterium leprae</em>; Multibacillary leprosy.</p>
