“For decades, diseases like trachoma, and lymphatic filariasis burdened the people of Lao PDR. One by one, thanks to determined national efforts and robust international support, these burdens have been lifted. Trachoma in 2017, and lymphatic filariasis in 2023. Malaria cases fell to 272 in 2025. Now, we are taking on schistosomiasis.
A parasitic disease spread by freshwater snails, schistosomiasis has long posed a significant public health risk in Lao PDR, particularly in communities along the Mekoang River where infection rates in the 2003 exceeded 40% in some areas. The parasite’s microscopic larvae thrive in the very water that sustains daily life – for washing, fishing, and transport. The disease can cause debilitating symptoms like an enlarged liver, bleeding when going to the toilet, and even severe liver damage – with potentially fatal complications.
Efforts over the decades mean schistosomiasis is now found only in southern Champasack Province, with 120 000 people estimated to be at-risk across 202 villages. While sustained efforts have significantly reduced infection rates (less than 1% in high-risk areas), thousands are still affected, especially children”
