Interventions

In the first step, in-depth parasitological surveys are carried out to identify 150 schools where the prevalence of S. haematobium (i.e., number of infections) amongst schoolchildren is greater than 2

Design outcomes

Primary

Measure	Time frame
Identification of the most cost-effective strategy that is able to reduce S. haematobium infection from high prevalence levels measured by change in prevalence and intensity of Schistosoma haematobium infection in 9- to 12-year-old children over the four years of intervention.	—

Secondary

Measure	Time frame
1. Prevalence and intensity of S. haematobium infections in 9- to-12- year-old schoolchildren. 2. Prevalence and intensity of S. haematobium infections in first-year schoolchildren. 3. Control of morbidity due to S. haematobium (reduction of the prevalence to <10%) in the 150 schools 4. Identification of S. haematobium risk factors 5. Mapping and prediction of the distribution S. haematobium in Cabo Delgado Region, Mozambique. Measured by changes in force of transmission, as assessed by infection prevalence and intensity of S. haematobium in first-year students and adults.	—
