Proposed criteria to assess existing levels of integration.

Level of Integration	Sublevels of Integration	Criteria
Policy and institutional	Policy	1. Existence of a national policy addressing integrated surveillance for a specific pathogen
		2. Existence of a policy addressing integrated surveillance for a specific pathogen at subnational level
	Institutional	3. Existence of agreements among the institutions involved in human/animal/entomological surveillance for the specific pathogen
		4. Existence of coordination mechanisms among the institutions involved
		5. Existence of identified focal points for each human/animal/entomological surveillance for the specific pathogen
Data collection and analysis	Interoperability mechanisms at data collection	6. Existence of integrated data collection tools
		7. Existence of activation mechanisms of human surveillance based on signals from animal/entomological surveillance
		8. Other interoperability mechanisms at data collection level
	Interoperability mechanisms at data analysis	9. Presence of database exchange/merging/other mechanisms to facilitate joint analysis among sectors.
		10. Performance of joint/integrated data analysis among the different surveillance sectors
		11. Other interoperability mechanisms at data analysis level
Dissemination	-	12. Existence of joint results dissemination mechanisms (e.g., bulletins, reports, papers, media reports, websites, etc.)
