Environmental factors such as water temperature, sanitation, and snail population density play a crucial role in the spread of Schistosoma infections. Poor sanitation allows parasite eggs to contaminate freshwater, where snails act as intermediate hosts. Warm, stagnant water promotes snail breeding, increasing transmission risks for communities relying on such sources for bathing or irrigation. Climate change and human activities like dam construction further expand habitats suitable for snails, intensifying infection rates. Effective control requires improved water management, sanitation, and access to treatment. Pharmaceutical suppliers offering mebendazole wholesale also contribute by ensuring affordable antiparasitic medications for endemic regions.
