【 摘 要 】

BackgroundIn the Adami Tulu District, indoor residual spraying (IRS) and insecticide-treated nets (ITNs) has been the main tool used to control malaria. The purpose of this study was to assess the effect of IRS and ITNs control strategies in Aneno Shisho kebele (lowest administrative unit of Ethiopia) compared with Kamo Gerbi (supplied ITN only) and Jela Aluto (no IRS and ITNs), with regards to the prevalence of malaria and mosquito density.MethodsCross-sectional surveys were conducted after heavy rains (October/November, 2006) and during the sporadic rains (April, 2007) in the three kebeles of Adami Tulu District. Malaria infection was measured by means of thick and thin film. Monthly collection of adult mosquitoes from October-December 2006 and April-May 2007 and sporozoite enzyme-linked immunosorbent assay (ELISA) on the collected mosquitoes were detected. Data related to the knowledge of mode of malaria transmission and its control measures were collected. Data collected on parasitological and knowledge, attitude and practice (KAP) surveys were managed and analysed using a statistical computer program SPSS version 13.0. A P-value <0.05 was considered to be statistically significant.ResultsThe overall prevalence of malaria was 8.6% in Jela Aluto, 4.4% in Kamo Gerbi and 1.3% in Aneno Shisho in the two season surveys. The vector, Anopheles gambiae s.l., Anopheles pharoensis and Anopheles coustani were recorded. However, sporozoite ELISA on mosquito collections detected no infection. The difference in overall malaria prevalence and mosquito density between the three kebeles was significant (P<0.05).ConclusionsThe present study has provided some evidence for the success of ITNs/IRS combined malaria control measures in Aneno Shisho kebele in Adami Tulu District. Therefore, the combined ITNs/IRS malaria control measures must be expanded to cover all kebeles in the District of Ethiopia.
