Surveillance assumptions over the malaria control-elimination spectrum
| Surveillance activities | Coverage rate | Stratification criteria |
|---|---|---|
| Epidemiological and entomological surveillance | 100% of population at risk | All areas |
| Operational research | 1 household and 1 health facility malaria survey modules every 3–5 years | All areas |
| Case/foci investigation and classification activities | 15% of cases | 4≤API<5 |
| 30% of cases | 3≤API<4 | |
| 50% of cases | 2≤API<3 | |
| 70% of cases | 1≤API<2 | |
| 90% of cases | 0.5≤API<1 | |
| 100% of cases | 0.5<API | |
| Proactive case detection | 10% of population at risk | 0.5≤API<1 |
| 5% of population at risk | 0.5<API |
