Introduction: This study investigated the distribution and abundance of snails that can transmit schistosomiasis, a parasitic disease, in Kisangani, Democratic Republic of Congo. Materials and Methods: Five swampy sites were selected based on reported schistosomiasis cases and local knowledge of contact with water and snail presence. Non-probabilistic (convenience) sampling was employed. Results: Eight snail species were found, all of which can transmit various types of schistosomiasis or other diseases. The identified snail species can transmit schistosomiasis caused by Schistosoma mansoni, S. haematobium, and potentially S. intercalatum, as well as fascioliasis, another parasitic disease. Snail densities were high in the Onane, Kakole, and Gouvernorat sites, which are rivers and water points potentially contaminated with human waste. Cases of schistosomiasis have been reported in all Health Zones where snail samples were collected. Conclusion: This study provides valuable data on the distribution of snails that can transmit schistosomiasis in Kisangani. Further research is needed to better understand the schistosomiasis situation and develop control strategies.
