Análise do perfil epidemiológico da Esquistossomose no nordeste brasileiro no período de 2011 a 2021

Abstract

Schistosomiasis is a disease caused, in Brazil, by Schistosoma Mansoni, it has established itself in this country with slave trade and remains until the present moment. Of the nines Brazilian states that are endemic for this disease, seven of them are located in the Northeast showing that from the insertion of this disease in the country to nowadays, it’s a public health problem in these states, both for the precarious conditions of basic sanitation as being close to water regions, conditions that favor the proliferation and maintenance of intermediate hosts. The objective of this study is to analyze the epidemiological situation of schistosomiasis in the Brazilian Northeast, from 2011 to 2021. The epidemiological study of the ecological type had Northeast as the place of analysis. The analysis was performed through data obtained from the Information System of the Schistosomiasis Control Program being released by the electronic platform of the Informatics Department of the Unified Health System. About the intermediate hosts, Biomphalaria tenagophila positives was only found in Bahia, and in this region and in Piauí there was the presence of Biomphalaria glabrata positives, in this study the Biomphalaria straminea was detected in Bahia, Maranhão, Sergipe and Alagoas, noting that the positivity of the snails captured has been decreasing over the years analyzed and consequently the number of cases of the disease. The study observed that the performance of diagnostic tests for schistosomiasis suffered a 50% reduction in the period studied and treatment coverage showed a 20% failure in the Northeast states. Therefore, it is important to implement effective control actions to reverse this condition, which can cause the reemergence of schistosomiasis in this territory with the emergence of more serious cases of this disease and promote the occurrence of new cases
