摘要

引用本文为:Alegria Moran R, Lazo A, Urcelay S, Hamilton West C.利用空间工具对智利中部后院生产系统中高影响人畜共患病病原体的监测设计。墨西哥兽医局。2017; 4(1)。智利后院生产系统(bps)的具体位置仍然不清楚,这给设计监测活动以及时发现对健康有高影响的人畜共患病原体(如禽流感和沙门氏菌)带来了困难。本研究旨在证明空间工具的使用,以改善智利中部bps的监测。在瓦尔帕莱索省、解放者贝尔纳多·奥希金斯将军省和大都市区的15个省进行分层和比例随机抽样。在这次抽样中,检测到329个bps。在第一阶段,在研究区域内随机分配329个采样点,寻找与家禽或猪养殖有关的bps。然后,通过在每个点周围5公里半径内搜索农村或半农村地区、附近的作物和房屋或小城镇的存在,通过遥感和实地对这些随机点进行验证,而在山上或水源(湖泊或河流)上分配的点则被丢弃。超过70%的采样点被正确分配。在洛斯安第斯、科迪勒拉和查卡布科,不到50%的点被分配在可行的抽样区域内。在所有采样点中,89%的采样点符合5公里半径标准,而在瓦尔帕莱索、科迪勒拉和卡恰波尔省,超过20%的采样点在半径标准之外。这项研究是智利首次探索bps的位置和卫生状况。由于缺乏对bps具体地点的了解,在实地活动中对其进行鉴定对病原体监测来说成本很高。我们认为,在BPS监测设计中使用空间工具是医疗保健管理的重要支持。图1所示。随机抽样点按省分配使用ArcGIS®10和兼容的区域检测,使用自由的空间工具。A.随机采样点的研究区域。研究区域和省份:(1)佩托尔卡;(2)瓦尔帕莱索;(3)奎洛塔;(4)圣费利佩;(5)安第斯山脉;(6)圣安东尼奥;(7) Melipilla;(8) Chacabuco;(9)圣地亚哥;(10)山脉;(11) Talagante;(12) Maipo;(十三)胭脂红;(14) Cachapoal;(15)科尔查瓜。B.位于安第斯山脉的随机点(红色图钉)和5公里搜索区域(黄色圆圈)。C. 5公里以内的随机点(红色图钉)和抽样候选后院农场(黄色桨)。
