Table 1 Types of interventions in vector control and their limitations
Control methods | Advantages | Limitations |
|---|---|---|
Environmental hygiene (eliminates vector’s nests, etc.) | Efficacy > 50% | Necessitates community-guided actions |
Indoor Residual Spraying (IRS) | Efficacy 60% | Harmful effects of residues, high cost, resistant strains of mosquitoes |
Intermittent Preventive Treatment (IPT) | Efficacy 56% | May enhance drug resistance, use restricted for pregnant women and children < 5 years |
Insecticide treated mosquito bed nets | Efficacy 50% | High cost, poor adherence of rural communities, harmful effects of residues, resistance |
Biological control | No direct harmful effects on humans | Cost, genetic risks |
