高致病性禽流感(HPAI)H5N1病毒在亚洲持续存在，对家禽、野生鸟类和人类构成威胁。东南亚以前的工作表明，HPAI H5N1风险与家鸭和人有关。其他研究讨论了候鸟在HPAI H5N1远距离传播中的作用。然而，局地持续性和远距离扩散之间的相互作用却从未被研究过。我们将以前的地理空间风险分析扩展到包括南亚和东南亚，并将分析与卫星跟踪的野生水禽沿中亚飞行路线的迁徙数据相结合。我们发现，家鸭种群是描述南亚家禽中HPAI H5N1传播风险的主要因素，其他风险因素，如人口和鸡密度，与这些地区的HPAI H5N1风险有关。我们还发现，卫星追踪的鸟类(白头鸭和两只斑头雁)揭示了通过我们的风险模型在印度和孟加拉国发现的HPAI H5N1热点与2009年5-6-7月中国(青海湖)、蒙古和俄罗斯爆发的野生鸟类之间的直接时空联系。这表明，HPAI H5N1的大陆尺度动态是由家鸭划定的一些持久性区域构成的，这些持久性区域通过罕见的迁徙水禽传播连接在一起。本文的在线版本(doi：10.1007/s10393-010672-8)包含补充材料，授权用户可以使用。
Highly pathogenic avian influenza (HPAI) H5N1 virus persists in Asia, posing a threat to poultry, wild birds, and humans. Previous work in Southeast Asia demonstrated that HPAI H5N1 risk is related to domestic ducks and people. Other studies discussed the role of migratory birds in the long distance spread of HPAI H5N1. However, the interplay between local persistence and long-distance dispersal has never been studied. We expand previous geospatial risk analysis to include South and Southeast Asia, and integrate the analysis with migration data of satellite-tracked wild waterfowl along the Central Asia flyway. We find that the population of domestic duck is the main factor delineating areas at risk of HPAI H5N1 spread in domestic poultry in South Asia, and that other risk factors, such as human population and chicken density, are associated with HPAI H5N1 risk within those areas. We also find that satellite tracked birds (Ruddy Shelduck and two Bar-headed Geese) reveal a direct spatio-temporal link between the HPAI H5N1 hot-spots identified in India and Bangladesh through our risk model, and the wild bird outbreaks in May–June–July 2009 in China (Qinghai Lake), Mongolia, and Russia. This suggests that the continental-scale dynamics of HPAI H5N1 are structured as a number of persistence areas delineated by domestic ducks, connected by rare transmission through migratory waterfowl.
