Figure 3.

Examples of transmission clusters inferred from the global network shown in Figure 1. Node size is proportional to relative degree (number of edges per node). Edge lengths are optimized for visual presentation and do not represent genetic distances between potential transmission partners. Colors correspond to geographic regions in Figure 1.
