Water, Sanitation and Hygiene

Swiss TPH works on aspects of water, sanitation and hygiene (WASH) in countries where drinking water is scarce and where poor hygiene is a leading cause of infectious disease. WASH plays a major role in integrated approaches to fight helminth infections in Africa and Asia. Moreover, experts improve sanitation facilities in health centres or schools, teach pupils or household members in questions related to food and kitchen hygiene or assess people’s health risks arising from contaminated water bodies.

Most people in rural Tanzania are dependend on public wells.

Swiss TPH works towards bilharzia elimination on Zanzibar.

Towards Bilharzia Elimination in Zanzibar and Pemba

Swiss TPH supports the government of Zanzibar to eliminate bilharzia in Zanzibar and Pemba islands. During a five-year study, experts diagnose and treat schoolchildren in 45 communities. They reduce the snail population acting as intermediate hosts and regularly assess changes in water and sanitation infrastructure. The study is likely to offer new insights into what has to be done to ultimately eliminate bilharzia disease apart from preventive chemotherapy only.

The lack of latrines is a major cause of helminth infections in Lao PDR.

Latrines Protect the Rural Population in Lao PDR

Large parts of the rural population in Lao PDR suffer from chronic helminth diseases caused by a lack of sanitary facilities. People swim and wash themselves in stagnant water and fall victim to schistosomes the parasites causing bilharzia. Together with Laotian researchers, Swiss TPH showed that latrine building drastically reduces the infection with schistosomes.
