This study compared the costs and effects of insecticide permethrin)-treated bed net ITN) use in children less than five years of age in an area of intense, perennial malaria transmission in western Kenya. The data were derived from a group-randomised controlled trial of ITNs in an area of intense perennial malaria transmission in Western Kenya conducted between 1996 and 1999. The annual net cost per life-year gained was US $34 and the net annual cost per case of all-cause sick child clinic visit averted was US $49. After taking account a community effect, protection from malaria afforded to non-ITN users who lived within 300 meters from users, these estimates decreased to US $25 and US $38 respectively. This study provides further evidence that ITNs are a highly cost-effective use of scarce health care resources.
