New Solutions for Global Control of Parasitic Infections: The Case of Schistosomiasis

Main content start

Funding Year: 2013

Research Areas: Food Security, Freshwater, Natural Capital, Public Health

Regions: Africa, Asia, South America

Instead of treating a debilitating parasitic infection called schistosomiasis with drugs, this project aims to develop methodologies for controlling the snail populations that are the cause of the disease in developing countries, particularly those where dams and water projects have greatly expanded freshwater habitats for snails. Traditional drug treatments invariably end up in reinfection, as parasite reservoirs remain undisturbed. This project introduces river prawns, a native crustacean predator that likes to consume snails, as an environmentally safe and effective snail control option. This approach might offer a triple win solution by amplifying the positive effect of traditional drug treatment, possibly eradicating the disease from some areas, and offering a source of protein and marketable goods.

Since beginning field work, the Upstream Alliance, as the researchers call their initiative, has broadened its focus to encompass a range of potentialnatural solutions to global health problems, and has attracted millions of dollars in funding from organizations such as the Bill and Melinda Gates Foundation and the National Science Foundation.
