Schistosomiasis trends and control efforts: a global perspective from 1990 to 2050.

Background: Schistosomiasis is a chronic parasitic disease primarily endemic to tropical and subtropical regions, posing significant challenges to public health and economic development. Despite progress in global control efforts, the disease continues to be a major public health concern in high-burden countries such as China, Brazil, and Nigeria. This study seeks to assess the effectiveness of schistosomiasis control measures in these countries and on a global scale.
