Dispersal History of Powassan Virus Lineage 2 Viruses

Caption

Reconstruction of the dispersal history of Powassan virus lineage 2 viruses inferred by a spatially-explicit phylogeographic analysis. The highly focal distribution of the virus, with rare long-distance dispersal events, is particularly clear in Connecticut (see zoomed inset). Besides a single dispersal event between locations 1 (Westport) and 2 (Redding), the researchers did not observe mixing between the 5 distinct locations in Connecticut.
