在过去的一个世纪里，航空旅行网络的规模和复杂性急剧增加。如今，每年有2960万个定期航班，每年运送旅客约27亿人次。该网络的迅速扩张日益将病媒传播疾病流行地区与世界其他地区联系起来，导致全球卫生系统在病媒传播病原体输入和病媒入侵事件方面面临挑战。在这里，我们描述了一种用户友好的基于网络的 GIS 工具的开发：媒介传播疾病航空公司输入风险工具 (VBD-AIR)，以帮助更好地确定机场和航空公司在媒介传播疾病传播和传播中的作用。收集了模拟全球疾病和病媒分布的空间数据集，以及气候和空中网络交通数据。将这些组合起来，通过航空旅行得出输入性感染、输入性病媒和继续传播的相对风险指标，并将其纳入具有分布式 GIS 组件的模型-视图-控制器框架中的三层服务器架构中。建立了一个用户友好的门户网站，可以动态查询空间数据库以提供相关信息。所构建的 VBD-AIR 工具使用户能够探索病媒传播传染病（疟疾、登革热、黄热病和基孔肯雅热）的全球分布模型和国际航空服务航线之间的相互关系，以量化病媒和病媒传播疾病通过航空旅行输入和传播的季节性变化风险，形成证据基础以帮助规划缓解策略。 VBD-AIR 工具可从 http://www.vbd-air.com 获取。 VBD-AIR 支持数据流，该数据流将不同但互补的数据集生成分析结果，并在网络地图上以有组织的制图方式呈现，以评估航空旅行网络上媒介传播疾病的移动。构建的框架通过媒介传播疾病的本体模型分离功能模块，提供了灵活且强大的信息学基础设施。 VBD-AIR 工具旨在作为一个证据基础，为广大用户可视化航空旅行引起的媒介传播疾病的风险，包括州和地方政府的规划者和决策者，特别是国际和国内机场负责规划健康风险和分配有限资源的人员。
Over the past century, the size and complexity of the air travel network has increased dramatically. Nowadays, there are 29.6 million scheduled flights per year and around 2.7 billion passengers are transported annually. The rapid expansion of the network increasingly connects regions of endemic vector-borne disease with the rest of the world, resulting in challenges to health systems worldwide in terms of vector-borne pathogen importation and disease vector invasion events. Here we describe the development of a user-friendly Web-based GIS tool: the Vector-Borne Disease Airline Importation Risk Tool (VBD-AIR), to help better define the roles of airports and airlines in the transmission and spread of vector-borne diseases. Spatial datasets on modeled global disease and vector distributions, as well as climatic and air network traffic data were assembled. These were combined to derive relative risk metrics via air travel for imported infections, imported vectors and onward transmission, and incorporated into a three-tier server architecture in a Model-View-Controller framework with distributed GIS components. A user-friendly web-portal was built that enables dynamic querying of the spatial databases to provide relevant information. The VBD-AIR tool constructed enables the user to explore the interrelationships among modeled global distributions of vector-borne infectious diseases (malaria. dengue, yellow fever and chikungunya) and international air service routes to quantify seasonally changing risks of vector and vector-borne disease importation and spread by air travel, forming an evidence base to help plan mitigation strategies. The VBD-AIR tool is available at http://www.vbd-air.com. VBD-AIR supports a data flow that generates analytical results from disparate but complementary datasets into an organized cartographical presentation on a web map for the assessment of vector-borne disease movements on the air travel network. The framework built provides a flexible and robust informatics infrastructure by separating the modules of functionality through an ontological model for vector-borne disease. The VBD‒AIR tool is designed as an evidence base for visualizing the risks of vector-borne disease by air travel for a wide range of users, including planners and decisions makers based in state and local government, and in particular, those at international and domestic airports tasked with planning for health risks and allocating limited resources.
