Historic Travel of H7N9 HA Gene

Caption

This image shows traffic of the HA segment of H7N9 influenza within China, Taiwan and Hong Kong, 2013–2014. Larger and darker nodes are hubs involved in the most shortest paths between places. Small white nodes are relatively isolated. The size of the arrowheads indicates the frequency and directionality of transmission.
