Schools, as learning institutions, should offer a hygienic environment and include education related to reduction of environmental disease transmission. The conditions of rural schools in Colombia are often favorable for diseases like dengue and diarrhea which are related to water management, solid waste disposal, and sanitary conditions. The presence of Aedes aegypti can be reduced by adequate water storage management and solid waste disposal systems to reduce mosquito breeding sites. This together with well-maintained sanitation and hygiene training aims to integrate local protection and learning of risk factors both for dengue and diarrhea diseases. The main objective of this project is to reduce diarrheal disease and dengue vector infestation in rural schools by implementing a set of integrated interventions. Additional outcomes are to reduce school absence episodes and advancing knowledge and practices about these diseases in both teachers and pupils.
The study is carried out in the 34 rural schools, 17 in each of the municipalities of La Mesa and Anapoima, Cundinamarca department. These are located at an altitude of 700-1200 m.a.s.l, with an annual average temperature of 22-25°C. In total the number of pupils is 800 aged 5-16 in grades 0 to 5.
This is a 2x2 factorial cluster randomized controlled trial, with two sets of interventions; dengue and diarrhea. Schools were randomized to one of four arms: dengue interventions, diarrhea interventions, both sets of interventions, and control; stratified by municipality. Each school receives one, both, or none of the interventions; control schools will receive the interventions at the end of the project. Diarrhea interventions are: 1) Ceramic filters for clean drinking water, 2) Liquid soap for hand washing and cleaning kit for restrooms, and 3) Washing and covering of drinking water tanks (with plastic covers or nets). Dengue interventions are: 1) Covering of tanks, 2) Application of the insect growth-regulator pyriproxyfen to tanks, when covering is not possible, 3) Solid waste collection, and 4) Insecticide impregnated curtains in classrooms. These interventions are supported by educational and communication components in the form of teacher’s guides, posters and focal groups work.
