Table 2 Scoring methodology for micro-stratification of malaria risk in Nepal

From: Micro-stratification of malaria risk in Nepal: implications for malaria control and elimination

Level 1 Overall risk Sum of level 2 X 100%
Level 2 response* wt. Indicators (wt.) Disease burden (0.3) Ecology (0.5) Vulnerability (0.2)
Level 3 Variable response API in 3 years Transmission risk Population movement
Response value High (1.0)—H
Mod (0.6)—M
Low (0.1)—L
No (0.0)—N
Average API ≥ 1.0—H
Average API 0.01 to 0.99—M
Average API is 0—L
Combination of geo-ecosystem and vector species
(refer Table 1)
- Frequent movement to forests and development areas (high risk)—H
- Visit to forest is infrequent but visit to high risk areas is frequent (moderate risk)—M
- Movements to above areas are infrequent but endemic areas in Nepal or India is frequent (low risk)—L
- Movement to non-endemic areas only (no risk)—N
  1. *Level 2 response was categorized by a total of 100%
