Fig 8
Example of socioeconomic inequalities in schistosomiasis: association between S. haematobium prevalence (%) and educational attainment in South Kordofan State, Sudan (2009) [6].
South Kordofan State is located in the south of Sudan, bordering South Sudan. A total of 1,826 adults (aged >18 years) were recruited from all nine localities (36 villages or towns) of South Kordofan State. Urine samples were examined for the presence of S. haematobium, and a questionnaire on demographics and economic status of the family head was administered. Overall prevalence of S. haematobium eggs was 6.9%. Infection prevalence was higher among people with a lower educational attainment.
