ABSTRACT

Schistosomiasis, one of the most prevalent chronic diseases and a major parasitic infection in tropical areas, is highly related to poverty and poor sanitary conditions. In recent decades, the World Health Organization (WHO) recognized schistosomiasis as the third most prevalent endemic parasitic disease, after malaria and amebiasis. Moreover, ecotourism increases the number of individuals infected with schistosomiasis worldwide, introducing the disease into new areas (1). One of its most severe complications is pulmonary arterial hypertension (PAH); thus, schistosomiasis-associated pulmonary arterial hypertension (Sch-PAH) may be the most prevalent form of PAH worldwide (2).
