MATERIAIS E MÉTODOS:  Estudo observacional, retrospectivo e descritivo, baseado na análise de dados secundários registrados pelo Laboratório de Malacologia do Instituto Evandro Chagas referentes ao período de 2020 a 2024. As informações foram avaliadas para mapear a distribuição espacial dos moluscos e identificar áreas de maior concentração e risco de ocorrência de esquistossomose.  RESULTADOS:  Foram analisados 5.736 exemplares pertencentes às espécies Biomphalaria glabrata, Biomphalaria straminea e Biomphalaria tenagophila. A taxa de infecção natural foi de 1,2% (67/5.736), com positividade para Schistosoma mansoni registrada apenas em B. glabrata. A análise espacial indicou áreas críticas nos distritos administrativos DAGUA e DASAC, além da presença de focos próximos a pontos turísticos da cidade. Os resultados contribuem para o fortalecimento da vigilância em saúde e ambiental em Belém, especialmente em um momento estratégico para a cidade, que sediará a COP30.  CONCLUSÃO:  A identificação de focos próximos a áreas turísticas reforça a necessidade de ações preventivas integradas, visando proteger a população e os visitantes da capital paraense.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[ABSTRACT  OBJECTIVE:  To analyze the distribution and natural infection of Biomphalaria snails in the municipality of Belém, aiming to identify critical areas of epidemiological risk for schistosomiasis.  MATERIALS AND METHODS:  This observational, retrospective, and descriptive study was based on the analysis of secondary data recorded by the Malacology Laboratory of Evandro Chagas Institute, from 2020 to 2024. The information was evaluated to map the spatial distribution of snails and identify areas with higher concentration and risk of schistosomiasis occurrence. RESULTS: A total of 5,736 specimens were analyzed, belonging to the species Biomphalaria glabrata, B. straminea, and B. tenagophila. The natural infection rate was 1.2% (67/5,736), with Schistosoma mansoni detected only in B. glabrata. Spatial analysis revealed critical areas in the administrative districts DAGUA and DASAC, as well as foci near tourist sites in the city. The results contribute to strengthening health and environmental surveillance in Belém, especially at a strategic moment for the city, which will host COP30.  CONCLUSION:  The identification of foci near tourist areas highlights the need for integrated preventive actions to protect the population and visitors of the capital of Pará.]]></p></abstract>
