Anopheles stephensi was reported susceptible to malathion,propoxur,primphos-methyl,lambdacyhalothrin permethrin and deltamethrin,and resistant to DDT and dieldrin in the area.During the study period a total of 10 665 positive cases were reported,mainly due to local transmission (99.6%).Plasmodium vivax was the main causative agent followed by Plasmodium falciparum. There were reports about drug resistance of Plasmodium falciparum in the area.Conclusions: Using different parameters,Minab was classified into 3 strata.A plan was designed based on described goal,objectives and targets.The approaches of this plan were categorized into:health education,early detection and correct treatment,and vector control.Main constraints of these approaches are population movement between Iran,Pakistan and Afghanistan;vector control challenges at district,inadequate skilled medical staff in malaria case management and weak inter-sectorial coordination for malaria control,especially in urban areas.展开更多
