Riassunto: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 cascade of temporal events allowing sporadic amplification to outbreak levels was discussed within a future perspective.
