对2004年发生在阿根廷西北部Tartagal的登革热疫情的传播动态进行了调查。9共记录了487例疑似登革热病例并进行了地理参照。绘制了疫情爆发109天的每日病例图。这种传染病在11天之内影响了城市的大部分地区。病例的年龄分布与人口年龄分布不同。利用Knox检验概念分析了病例的时空聚类性。病例的空间和时间地理参照结果显示了可能与昆虫学和流行病学因素有关的爆发亮点和传播模式。基于LandSat 5 TM卫星影像合成的多波段影像，建立了环境风险预测模型。遥感数据和空间统计作为登革热监测战略和预防的景观流行病学工具的潜力和局限性进行了讨论。(c)2007 Elsevier B.V.保留所有权利。
The spreading dynamic of the 2004 dengue fever outbreak that occurred in Tartagal, Northwestern Argentina, was investigated. 9 A total of 487 suspected dengue cases were recorded and geo-referenced. Maps of daily cases were generated for the 109 days of the outbreak. The epidemic affected the majority of the city within I I days. The age-distribution of the cases was different from the population age-distribution. The spatio-temporal clustering of the cases was analyzed using Knox test concept. Results of the space and time geo-referencing of the cases showed outbreak spotlights and spreading patterns that could be related to entomologic and epidemiologic factors. An environmental risk prediction model was developed based on a synthetic multi-band image created from LandSat 5 TM satellite image. The potential and limitations of remote sensing data and spatial statistics as landscape epidemiology tools for a dengue surveillance strategy and prevention are discussed. (c) 2007 Elsevier B.V.
