<p>This study evaluated leprosy rates in Rio Grande do Sul, an area with a historically low prevalence. However, recent studies are lacking.</p>

<div>
<p><strong>METHODS:</strong></p>

<p>Data extracted from a National Database were analyzed for clinical features and compared to 1980s data. Tendency was assessed via stationarity analysis.</p>
</div>

<div>
<p><strong>RESULTS:</strong></p>

<p>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.</p>
</div>

<div>
<p><strong>CONCLUSIONS:</strong></p>

<p>Leprosy is controlled in RS, but most cases are multibacillary. Early identification is important to avoid disabilities due to late diagnosis.</p>
