Abstractbackground and objectivesdeferral for travel to malaria-endemic areas has excluded many blood donors in iran. to determine the effect of these deferrals on blood availability, we decided to conduct the present study.materials and methodsin this cross sectional and retrospective study, the donors deferred due to malaria related risk factors from 2005-2010 in tehran blood transfusion center were sampled to be enrolled for analysis. the data were extracted from mak database by two different grouped keywords; 2827129 records of blood donor volunteers were surveyed. resultsout of the total number of volunteers, 23462 were deferred due to malaria from 2005-2010 in tehran blood transfusion center. the most frequent deferral causes related to malaria was shown to be travelling to malaria endemic areas. the trend of deferred volunteers due to malaria risks was shown to follow a descending pattern after relaxing the application of the present guideline for travel to very low-risk areas such as karbala. conclusions we estimated that the loss of blood donors with more than 7000 units of blood was prevented annually by accepting volunteers who travelled to very low malaria risk areas, but it seems more logical to conduct further studies for such policies.
