Bashagard district is one of the important malaria endemic areas in southern Iran. From this region a total of 16,199 indigenous cases have been reported in recent years. The aim of this study was to determine the situation of the disease and provide the risk map for the area. ArcGIS9.2 was used for mapping spatial distribution of malaria incidence. Hot spots were obtained using evidence-based weighting method for transmission risk. Environmental factors including temperature, relative humidity, altitude, slope and distance to rivers were combined by weighted multi criteria evaluation for mapping malaria hazard area at the district level. Similarly, risk map was developed by overlaying weighted hazard, land use/land cover, population density, malaria incidence, development factors and intervention methods. Our results reveal that the disease mainly occurs in north and east of the study area. Consequently the district is divided into three strata. Appropriate interventions are recommended for each stratum based on national malaria policy. Malaria hazard and risk map, stratification based on relevant information and data analyzing provide a useful method preparedness and early warning system for malaria control, although regular updating is required timely.
巴沙加尔德区是伊朗南部一个重要的疟疾流行区。近年来，该地区共报告了 16199 例本地疟疾病例。本研究旨在确定该地区的疟疾情况，并绘制该地区的风险图。ArcGIS9.2 用于疟疾发病率的空间分布制图。采用基于证据的加权方法获取传染病传播风险的热点。将温度、相对湿度、海拔、坡度和与河流的距离等环境因素进行加权多标准评价，以绘制区级疟疾危害区的地图。同样，通过叠加加权危害、土地利用/土地覆盖、人口密度、疟疾发病率、发展因素和干预方法来绘制风险图。我们的研究结果表明，该疾病主要发生在研究区的北部和东部。因此，该地区被分为三个层次。根据国家疟疾政策，为每个层次推荐了适当的干预措施。疟疾危害和风险图、基于相关信息和数据分析的分层为疟疾控制的准备和预警系统提供了一种有用的方法，尽管需要及时进行定期更新。
