Schistosomiasis mansoni is a neglected tropical disease with an important health impact on the affected populations in Brazil and worldwide. Thus, the objective of the study was to perform a retrospective analysis of the epidemiological situation of schistosomiasis mansoni and describe the actions to control the disease in the municipality of Feira Grande/AL, between 2008 and 2016. This is an ecological study, with data obtained from the Information System of the Surveillance and Control of Schistosomiasis Program (SISPCE), which generated the indicators: operational actions (Percentage of coproscopic exams performed) and epidemiological actions (Percentage of positivity, Percentage of non-treatment, and Proportion of infected per class of infection intensity). For each indicator the mean, standard deviation, minimum and maximum were calculated. In addition, it was analyzed whether the time series had a decreasing, stationary or increasing trend, as well as the annual growth rate. There were 1,159 (8.8%) reported cases of schistosomiasis in Feira Grande in the analyzed period. The percentage of tests performed remained below adequate coverage (<90%) throughout the period studied, with 2008, 2009, 2010 and 2013 showing average endemicity. The lowest treatment coverage occurred in 2014, 2016, and 2013. The proportion of infected (PI) with low amount of eggs per slide (PI-low) predominated throughout the studied period and, in the temporal evaluation, the indicator Proportion of no treatment showed an increasing trend. The results point to an insufficiency in the actions to control ECP, besides showing that the epidemiological indicators point to a resurgence of the disease in the municipality.
