• The analyzes showed that the COVID-19 pandemic impacted Schistosomiasis Control Program actions in endemic municipalities of Alagoas state. • Our results showed a decrease in the worked population analyzed in the state program in 2020 and 2021. • There was a reduction in the number of Kato-Katz tests performed in 2020 and 2021. • We identified a reduction in the number of diagnoses of all parasitic diseases analyzed in 2020 and 2021 in Alagoas, except Taenia sp., which had a considerable increase in new cases diagnosed in 2021; • Clusters of municipalities formed with a percentage of negative change, comprising the central regions and northeast of Alagoas (the state's coastal area). Schistosomiasis remains a serious public health concern in Brazil and the Schistosomiasis Control Program (PCE) was elaborated to assist in the control of the disease. Nevertheless, the irruption of the COVID-19 pandemic may have impacted the program. Herein, we assessed the impact of the pandemic on PCE actions in an endemic area in the region with the highest positivity rate for schistosomiasis in Brazil. We conducted an ecological, population-based study using data from the PCE of the state of Alagoas, between 2015 and 2021, to calculate the percentage of change. The temporal trend analysis was performed using the segmented log-linear regression model. To evaluate the spatial distribution of the data, choropleth maps were made showing the values of the% of change. Moran maps was elaborated to indicate the critical areas. Our analysis showed a decrease in the population surveyed in 2020 (-41.00%) and 2021 (-18.42%). Likewise, there was a reduction in the number of Kato-Katz tests performed (2020 = -43.45%; and in 2021 = -19.63%) and, consequently, a drop in the rate of positive tests (-37.98% in 2020 and -26.14% in 2021). Importantly, treatment of positive cases was lower than 80% (77.44% in 2020 and 77.38% in 2021). Additionally, spatial clusters with negative percentage values of up to -100% of the PCE indicators were identified mostly in the municipalities of the coastal areas that are historically most affected by schistosomiasis. Taken together, our analyzes corroborate that PCE actions in endemic municipalities of Alagoas were impacted by the COVID-19 pandemic. [ABSTRACT FROM AUTHOR]
