Introduction: The difficulties in coping with leprosy reaffirm the importance of epidemiological studies in different locations to better assess the magnitude of its endemicity. Objective: to analyze the distribution of new cases and leprosy detection coefficients in the state of Alagoas. Method: This is an ecological study. Leprosy cases reported in the municipalities of Alagoas were included. The study was based on records obtained in the National Notification System, from State Department of Health (2010-2019) and demographic data from the population census (2010). Association, spatial and trend temporal analysis were used. Results: 4,343 cases of leprosy were reported in the municipalities. The average rate of detection of new cases for the total population was estimated at 10.85, ranging from 12.57 (2010) to 11.63 (2019). The highest rate was estimated for the municipality of Santana do Ipanema (58.2), considered to be hyper-endemic. Rates with very high endemic values were observed in 13 municipalities. There was a downward trend in the mean number of cases in 2010-2014 (APC = -4.34, CI95%: -10.5-2.3) and an increase in 2015-2019 (APC = 3.04, CI95%: -15.1-25). The gross and Bayesian rates showed many municipalities with a high endemic characteristic, in the west, northwest, northeast and south regions. Conclusion: This study showed clusters in areas of greater socioeconomic vulnerability. It is recommended to plan preventive actions, to actively search for cases and to evaluate contacts in the identified areas.
