Abstract
Abstract
The present work aimed to evaluate the historical series of epidemiological data on schistosomiasis mansoni in the municipality of Barreirinhas, Maranhão, covering the period from 2000 to 2019. This is an exploratory ecological study, focusing on the following aspects: positive stool tests for Schistosoma mansoni, place of origin of those examined and year of examination. The information was extracted from the Schistosomiasis Control Program Information System (SISPCE) and subjected to descriptive static analysis, using absolute frequency and relative frequency, as well as calculations of incidence and prevalence rates. Over the period, 576 positive tests for schistosomiasis mansoni were reported, with greater frequency in 2005 (115 positives), 2002 (61 cases) and 2001 (56 registered). The male gender was more prevalent for schistosomiasis and the age group from 15 to 25 years old was the most affected. Notifications predominated in rural areas, but an increase was noted in peri-urban and urban areas. This result combines with the precarious situation of sanitation infrastructure in the affected locations and lack of health education. Knowing that schistosomiasis is a public health problem, it is essential to implement continuous monitoring and investigation actions in focal areas, as well as health education by public authorities among the population included in the historical list of infections.
