Over the past 10 years, there has been scale-up of treatment campaigns in a number of sub-Saharan countries, where most of those at risk live. Geographic Distribution The World Health Organization estimates that over million people are infected with schistosomiasis and million more are at risk in at least 76 countries. Forty-three percent of those infected had suffered from bloody diarrhea in the 2 weeks before the survey. Working with partners and the private sector, WHO has advocated for increased access to praziquantel and resources for implementation. Geographic distribution of S.

    japonicum, and S. mansoni. Two other species, more localized.
    The importance of schistosomiasis is shown by a survey of an island on Lake Victoria, Tanzania.

    Liver enlargement is common in advanced cases, and is frequently associated with an accumulation of fluid in the peritoneal cavity and hypertension of the abdominal blood vessels. However, a major limitation to schistosomiasis control has been the limited availability of praziquantel. Similar immigrant pockets of schistosomal infection exist in many other nontropical countries, especially in major cities. The control of schistosomiasis is based on large-scale treatment of at-risk population groups, access to safe water, improved sanitation, hygiene education, and snail control.

    Schistosomiasis is prevalent in tropical and subtropical areas, especially in poor communities without access to safe drinking water and adequate sanitation. An assessment of the status of transmission is being made in several countries. The economic and health effects of schistosomiasis are considerable and the disease disables more than it kills. It is generally agreed that the animal hosts of S. It affects primarily the colon, portal system and lungs.

    Inadequate hygiene and contact with infected water make children especially vulnerable to infection.

    Transmission occurs when people suffering from schistosomiasis contaminate freshwater sources with their excreta containing parasite eggs, which hatch in water. The WHO strategy for schistosomiasis control focuses on reducing disease through periodic, targeted treatment with praziquantel through the large-scale treatment preventive chemotherapy of affected populations.
