Prevalence of S. haematobium in persistent hot-spot and low-prevalence shehias

Table 1 shows the prevalence of S. haematobium in children visiting the primary schools located in any of the seven study shehias, stratified by survey year. The average S. haematobium prevalence across all three survey years in 9 – 12 years old schoolchildren was 20.0 % (95 % CI: 18.1 – 22.0) in the five persistent hot-spot shehias and 0.78 % (95 % CI: 0.0 – 1.5) in the two low-prevalence shehias. Schoolchildren in Koani shehia had the highest average prevalence of 26.4 % considering all surveys conducted in schools between 2012 and 2014 and also had the highest single-year prevalence of 37.6 % in 2013.
