Introduction: Schistosomiasis, a parasitic disease, is an important public health issue in Brazil, particularly Northern Brazil. Since the fi rst recorded occurrence of Biomphalaria glabrata in the States of Santa Catarina and Rio Grande do Sul, it has spread to South Brazil. Methods: Using the Information System for Notifi able Diseases (SINAN), we assessed the disease spread in Southern Brazil. Results: In Rio Grande do Sul, nine localities had confi rmed cases (n = 95, 2001-2013). Conclusions: We confi rmed disease expansion to Southern Brazil. We demonstrated the effectiveness of SINAN to monitor notifi able diseases. Our results are useful to develop preventive actions for schistosomiasis control.
