RESUMO
INTRODUCTION:: This study evaluated leprosy rates in Rio Grande do Sul, an area with a historically low prevalence. However, recent studies are lacking. METHODS:: Data extracted from a National Database were analyzed for clinical features and compared to 1980s data. Tendency was assessed via stationarity analysis. RESULTS:: Between 1990 and 2011, 4,770 cases were reported (0.21/10,000 inhabitants; 95% CI = 0.19-0.24). Detection was slightly higher among males, 1.9% cases were among children and most multibacillary (74.7%) at diagnosis. CONCLUSIONS:: Leprosy is controlled in RS, but most cases are multibacillary. Early identification is important to avoid disabilities due to late diagnosis.
