Thailand General Health Risks: Schistosomiasis

Infection is transmitted by snails living in fresh water such as lakes, rivers, streams and ponds in Africa, and some countries in Southeast Asia, South America, and the Caribbean.

Schistosomiasis transmission is interrupted. The country is awaiting evaluation and verification from the World Health Organization for confirmation.

Public health authorities report no new human cases of S. mekongi and await WHO evaluation and verification. Cases were previously reported in the region of Chong Mek (near the confluence of the Mun and Mekong rivers) in Ubon Ratchathani province on the border with Laos. Snail intermediate host: Neotricula aperta.
