几十年来，中国南方一直被认为是新发流感病毒的重要来源，因为主要宿主高密度地生活在集约化农业地区。然而，禽流感病毒（AIV）出现和传播的潜在条件尚未得到详细研究，特别是野鸭和家鸭（AIV流行病学的两个主要参与者）之间病毒传播的复杂时空相互作用。在这篇综合文章中，我们研究了禽流感在鄱阳湖传播的风险，鄱阳湖是一个散养鸭集约化生产和大量野生水禽的地区。综合分析表明，该地区自由放养的家鸭养殖较为密集，且与野鸭迁徙同步。在同一稻田的候鸟鸭到达和离开之前，雏鸭在收获的稻田中存在，可能会增加AIV传播的风险，并促进野生种群和家养种群之间的传播。我们提供了2008年春季从中国南方到韩国、俄罗斯和日本的野鸭迁徙与H5N1传播有关的证据，并得到野鸭迁徙记录和高致病性H5N1禽流感序列系统发育分析的支持。我们建议在这些地区实施基于农业实践的预防措施，以减少野鸭和家鸭之间的AIV传播强度。这需要让所有当地利益相关者参与讨论可行和可接受的解决方案。
For decades, southern China has been considered to be an important source for emerging influenza viruses since key hosts live together in high densities in areas with intensive agriculture. However, the underlying conditions of emergence and spread of avian influenza viruses (AIV) have not been studied in detail, particularly the complex spatiotemporal interplay of viral transmission between wild and domestic ducks, two major actors of AIV epidemiology. In this synthesis, we examine the risks of avian influenza spread in Poyang Lake, an area of intensive free-ranging duck production and large numbers of wild waterfowl. Our synthesis shows that farming of free-grazing domestic ducks is intensive in this area and synchronized with wild duck migration. The presence of juvenile domestic ducks in harvested paddy fields prior to the arrival and departure of migrant ducks in the same fields may amplify the risk of AIV circulation and facilitate the transmission between wild and domestic populations. We provide evidence associating wild ducks migration with the spread of H5N1 in the spring of 2008 from southern China to South Korea, Russia, and Japan, supported by documented wild duck movements and phylogenetic analyses of highly pathogenic avian influenza H5N1 sequences. We suggest that prevention measures based on a modification of agricultural practices may be implemented in these areas to reduce the intensity of AIV transmission between wild and domestic ducks. This would require involving all local stakeholders to discuss feasible and acceptable solutions.
