    Area of Science:

    • Tropical Medicine
    • Infectious Diseases
    • Public Health

    Background:

    • Schistosomiasis is a persistent endemic parasitic disease in tropical and subtropical regions, notably Africa.
    • Agro-engineering projects are increasing schistosomiasis transmission intensity and expanding its geographical range.
    • Despite advancements in control tools and successful demonstration programs, many endemic areas show static or worsening schistosomiasis situations.

    Purpose of the Study:

    • To analyze the reasons behind the static or worsening schistosomiasis situation in endemic areas.
    • To identify key factors impeding effective schistosomiasis control programs.
    • To highlight areas for improvement in public health strategy and technical interventions.

    Main Methods:

    • Review of trends in schistosomiasis prevalence and distribution.
    • Analysis of factors influencing control program effectiveness.
    • Discussion of public health significance, epidemiological assessment, and technical constraints.

    Main Results:

    • Schistosomiasis control is hampered by low prioritization due to underappreciated public health impact.
    • Lack of robust epidemiological assessments leads to insufficient guidance for control programs.
    • Technical limitations concerning drug efficacy and safety, alongside other control measures, pose significant challenges.

    Conclusions:

    • Effective schistosomiasis control requires addressing the low public health priority and improving epidemiological assessments.
    • Overcoming technical constraints in drugs and control measures is crucial for disease management.
    • A multi-faceted approach combining political will, scientific guidance, and technical innovation is needed to combat schistosomiasis effectively.
