 Figure 5 Phylogeographic analysis revealed global transmission patterns of human-associated S. suis. Countries of relevance in the map are colored. Geographic presence, inferred arrivals (arrows) and principal long-distance transmission events (line) are based on phylogeographic analysis. The date are the inferred values for the most recent common ancestor (taken from BEAST2). The origin of most transmission waves was Europe. One of these transmission waves was spread to China leading to two major outbreaks (Jiangsu and Sichuan) (red line).
