Table 1 Diarrhea and dengue interventions implemented in rural primary schools in La Mesa and Anapoima municipalities, Cundinamarca, Colombia

From: Diarrhea and dengue control in rural primary schools in Colombia: study protocol for a randomized controlled trial

Component Intervention Frequency of intervention Objectively verifiable indicators Sources of verification Expected outcome
(a) Diarrhea interventions (DIA)
Drinking water quality Drinking water filters Continuous Values of water quality parametersa Field collection Clean water supply
Cover drinking containers with lids Continuous Observational index: lid fitted correctly (yes/no) Field observation Clean water supply. Ensuring no additional contamination to water
Cleaning water storage containers At least once per semester Observational index: appearance clean (yes/no) Field observation + responsible municipal authority Clean water supply. Ensuring no additional contamination to water
Hygiene Promotion of hand-washing with soap Daily 1. Presence of soap (yes/no). Field observation survey (for indicator 1 and 2). Questionnaire (for indicator 3). Hand-washing practices carried out and maintained (as taught in educational campaign)
2. Availability of water for hand-washing (yes/no).
3. Frequency of hand-washing with soap by school pupils
  Promotion of proper use and cleaning of toilets Daily Toilet cleanliness score Field observation Eliminate potential routes for feces ingestion during toilet use
Education and training Educational campaign on diarrheal disease, hand-washing, hygiene, health and water relationships Monthly modules KAP score KAP questionnaire Children acquired proper hygiene and sanitation knowledge and practices
(b) Dengue interventions (DEN)
Adult mosquitoes Insecticide treated curtains Continuous Aedes aegypti adult mosquito density Field collections Reduce adult mosquito density
Immature mosquitoes Cover containers with lids or covers Continuous Aedes aegypti larval and pupal density Field collections Reduce immature mosquito density
Treatment with pyriproxifen in containers that cannot be fitted with lids or covers Continuous with weekly follow-up Aedes aegypti larval and pupal density Field collections Reduce immature mosquito density
Solid waste management Larval source control through solid waste management At least once per semester Number of positive Aedes aegypti immature breeding sites in solid waste Field observation Elimination of breeding sites
Education and training Educational campaign on dengue disease; vector biology, ecology, and control; role of solid waste; water and health relationships Monthly modules KAP score KAP questionnaire Children acquired knowledge and practices on dengue and mosquito control
  1. a In-situ: temperature, pH, electrical conductivity, total dissolved solids; Laboratory: Total coliforms, fecal coliforms, and E. coli.
