The prevalence of hookworm and of S. haematobium in rural Zambia.

The prevalence of hookworm and of S. haematobium in a representative sample of the rural population of seven provinces of Zambia was assessed during a National Nutrition Status Survey. A total of 7212 people of all age and sex groups were examined for hookworm, of whom 4920 (68%) provided a stool sample and of these 48.6% were positive. Regional figures ranged between 11.4% and 77.1%. No differentiation between species of hookworm was attempted nor was it possible to assess the worm load of the individuals surveyed. Hookworm is highly endemic within the rural areas and this is discussed in relation to its known effects on the general health of the population studied during the survey, and the impact of hookworm infestation on morbidity.
