    Hookworm infection and anaemia: approaches to prevention and control.

    Pawlowski ZS; Schad GA; Stott GJ

    Geneva, Switzerland, World Health Organization [WHO], 1991. vi, 96 p.

    WHO published this manual on the prevention and control of hookworm infection and anemia primarily for community health workers. The manual addresses the epidemiology, diagnosis, and management of these conditions. Its annexes provide details of appropriate examination techniques for hookworm and hookworm anemia surveys and sample survey considerations. It emphasizes the importance of thorough population surveys. The worldwide prevalence of infection with Ancylostoma duodenale and Necator americanus is about 25%. It occurs predominantly in developing countries, where prevalence may be as high as 80% in some areas. It is a major cause of iron deficiency anemia. Its presence indicates deficiencies in sanitation and health education. Many persons, including public health officials, are not interested in national control of hookworm infection, probably because it induces low mortality and it is technically difficult to measure and quantify hookworm-related morbidity. Control of hookworm infection and hookworm-related anemia is uncomplicated and effective. It consists of health education, effective sanitation, and treatment with antihelminthics and iron supplements. The manual's seven chapters cover the following: hookworms infecting humans; clinical pathology of hookworm infection; hookworm infection as a cause of anemia; epidemiology of hookworm infection; principles of prevention and control; assessing the situation; and practical prevention and control.
