The introduction, dispersal and establishment of West Nile virus in North America were reviewed, focusing on factors that may have enhanced receptivity and enabled the invasion process. The overwintering persistence of this tropical virus within temperate latitudes was unexpected, but was key in the transition from invasion to endemic establishment. The cascade of temporal events allowing sporadic amplification to outbreak levels was discussed within a future perspective.
本文回顾了西尼罗河病毒在北美洲的传入、传播和定殖过程，重点探讨了可能增强易感性并促进入侵过程的因素。这种热带病毒在温带纬度地区的越冬持久性出人意料，但这是从入侵到地方性定殖过渡的关键。本文还从未来的角度讨论了允许零星放大到爆发水平的时间事件级联。
