Background and Objectives: Schistosomiasis mansoni is a neglected chronic disease causedby Schistosoma mansoni, which is endemic in Brazil. It presents systemic involvement and itsclinical manifestations range from dermatitis to severe clinical syndromes, includingneurological and/or hepatic manifestations, such as liver cirrhosis. Although the incidence hasdecreased in the last decade, it is estimated that underreporting occurs. This study aimed to verifythe existence of underreporting and the persistence of the endemic character of schistosomiasisin a municipality in rural Minas Gerais (MG) in 2016. Method: This is a descriptive and crosssectional study based on secondary data related to positive results of parasitological andserological tests for schistosomiasis in residents of the municipality from seven of its eightclinical analysis laboratories. Results: In total, 29,266 tests were evaluated by all techniques, ofwhich 80 were positive and 50 confirmed, corresponding to an estimated 0.17% prevalence(95%CI 0.13-0.23%). In 2016, 31 cases of schistosomiasis were also reported in SINAN-MG.Conclusion: Schistosomiasis in Ponte Nova, MG, persists as epidemiological pattern ofendemicity and underreported surveillance operational situation. We highlight the importanceof strengthening monitoring and control actions for the disease, including of endemic areas forthe vector and early treatment of patients with positive PSE.
