Schistosomiasis is earmarked for elimination as a public health problem, while morbidity control is a priority for soil-transmitted helminthiasis (STH) by 2030. To develop targeted interventions for the two diseases, micro-mapping and an understanding of disease transmission dynamics across different age groups are necessary. This study determined the age-stratified and ward-level prevalence of schistosomiasis and STH in Chevakadzi ward, Shamva district, Mashonaland Central province, Zimbabwe.

Schistosomiasis-associated pulmonary arterial hypertension (Sch-PAH) is categorized as WHO Group I PAH because its clinical manifestations, laboratory and hemodynamic features share with PAH of other etiologies, such as idiopathic, heritable, HIV and autoimmune disorders. Sch-PAH is usually a life-threatening complication of hepatosplenic schistosomiasis characterized by changes in the vascular wall, remodeling and vasoconstriction with lesions primarily located in the precapillary segments of the pulmonary vasculature, which may result in a marked and sustained increase in pulmonary vascular resistance, right ventricular failure and ultimately death. Although egg deposition into lung and subsequent inflammatory cascades are key factors in the pathogenesis of Sch-PAH, the exact pathogenesis, course of disease and treatment of Sch-PAH remain largely uncertain.

Schistosomiasis has been subjected to extensive control efforts in the People's Republic of China (China) which aims to eliminate the disease by 2030. We describe baseline results of a longitudinal cohort study undertaken in the Dongting and Poyang lakes areas of central China designed to determine the prevalence of Schistosoma japonicum in humans, animals (goats and bovines) and Oncomelania snails utilizing molecular diagnostics procedures. Data from the Chinese National Schistosomiasis Control Programme (CNSCP) were compared with the molecular results obtained.

Parasitic diseases are common infectious diseases closely related to poverty, which are mainly endemic in the tropical and subtropical regions. Africa is the major epidemic area of parasitic diseases, and the global burden of malaria and schistosomiasis is over 85% in Africa. This paper reviews the disease burden, regional distribution and control strategies of the main parasitic diseases in Africa, in order to promote the prevention and control of parasitic diseases in this area.

Article Synopsis
  • - The study highlights the growing concern over the role of migrants in the transmission of schistosomiasis in China, particularly in regions like Hunan where the disease is endemic, despite control efforts.
  • - A survey revealed that migrants represent a significant portion of the population in these areas (53.6%) and have a higher infection rate compared to permanent residents, mainly due to less awareness and lack of protective measures.
  • - The findings suggest that current schistosomiasis control programs fail to adequately include migrants, especially since they are often absent during health interventions, which could contribute to continued disease transmission.
