| Popis: | Long-lasting insecticidal bednets (LLINs) are one of the major ways to control malaria and they are widely accepted worldwide by communities in areas affected by malaria. One LLIN costs about US$5 to manufacture and is effective for about 5 years. They have two kinds of protective effects-one for the people directly under the nets and one for the community at large. The second effect is important but often ignored. By achieving high community coverage to ensure a substantial community protection malaria-control efforts can be more powerful than when only individual protection is attempted. The direct effect of LLINs is to protect the people sleeping under them and it operates in three ways. First the insecticide kills some of the Anopheles mosquitoes after a few minutes. Second the LLIN repels a proportion of the mosquitoes after contact. Third the net acts as a mechanical barrier to biting. The mechanical barrier provides half or less of the protection which is why bednets without insecticide are less effective than treated ones. (excerpt) |
