Summary

Impact exerted by intestinal parasitic infections is much higher in developing countries. School-aged children are at higher risk from the burden of disease, because they specially have many parasitic infections. The poor health results in deficits in physical and cognitive development and educational achievements. Nowadays, there is huge commitment among the global community to control intestinal parasitic infections and to improve nutritional status of young children in developing countries. Large-scale anthelminthic drug administration through vertical control programmes is still required for the foreseeable future and is, therefore, recommended by the World Health Organization (WHO). However, due to the inevitability of re-infection in endemic areas, children need to be treated regularly, and once morbidity control is consolidated, the strategy must shift to transmission control emphasising access to clean water and adequate sanitation. To lower dependency on 'drug only' approach and to enhance sustainability, from the onset of control activities, complementary measures should be implemented, that depend on available resources. Therefore, the investigators are proposing to undertake a randomised controlled trial to assess the impact of simple and easy-to-do hand hygiene intervention packages (hand washing with soap and hand finger nail clipping) on intestinal parasitic infection prevalence, intensity and re-infection rates and on haemoglobin concentration and anaemia prevalence rates among 6-15 years old schoolchildren. Our results will provide solid evidence on if and how hand hygiene practice affects infection prevalence and re-infection rates, as well as, anaemia prevalence among the highly vulnerable age group.

Detailed description

The controlled prospective cohort study will be carried out in Kilte awlaelo wereda, north Ethiopia. A total of 216 households with at least one school-aged child (aged 6-15) will be randomly selected by systematic random sampling method. Different intervention packages will be randomised among households. Intervention activities will be implemented at household level, using the selected child within the household as study unit. If there are more than one child per randomised household all children will receive the intervention, but only two children, selected by simple random selection method, will be included in the trial. Selected children will be screened for intestinal parasitosis, following acquisition of signed informed consent, and will be recruited for the study after treatment. Parasite negative children in the respective households will be randomly allocated into intervention and control groups. Sequence allocation will be done in a central office by an individual who do not know and have no contact with the study sites and households. Each intervention and control group will have a fixed number of participants, and will be subjected to only one of the study interventions. Children and households in each group will be followed-up for 6 months by trained fieldworkers and the investigators according to a developed protocol throughout the study period. Parasitological, haemoglobin and anthropometric data will be collected at entry and after six months.
