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

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
