From: Seven decades towards malaria elimination in Yunnan, China
Strategy, interventions | Malaria transmission stratuma | Timing and frequency |
---|---|---|
Clearance of the infection source | ||
 Case management | High/medium/low: Clinical cases and laboratory-confirmed cases | Any time |
 Radical treatment | High: Individuals with a history of recent malaria; entire population or targeted populationb | Any time for individuals; MDA during non-transmission seasons. Usually, one round MDA during non-transmission seasons. In high-transmission areas, several rounds of MDA might be necessary, before and during transmission seasons |
Medium/low: Individuals with a history of recent malaria; entire population living in active foci or targeted populationb | ||
Chemoprevention | ||
 Intermittent preventive treatmentc | High: Entire population of villages and migrants | Start 1 month before the transmission season starts. Depending on the drugs used, application covered the entire transmission season; usually at least eight times per year |
Medium/low: Population in active foci, migrants | ||
Vector control | ||
 Indoor residual insecticide sprayingd | High: Houses and animal sheds in whole villages | During the transmission season. Depending on the duration of transmission seasons and the insecticide used, could be one, two or three rounds per year |
Medium/low: Houses and animal sheds in active foci | ||
 Treatment of larval breeding sites | High: Use chemicals | At the end of winter and the beginning of spring |
Medium/low: Use whatever available (e.g. herbal) |
