Main Article

Figure 4

Distribution curve of the predicted dates of the most recent common ancestor of the Shigella sonnei outbreak isolates, California, USA, 2023–2024. The plot shows the posterior density for the common ancestor times of the Shigella sequences collected in the San Francisco Bay, California, USA, area. For a single introduction, the common ancestor time provides a lower bound on the timing of the introduction into the San Francisco Bay area.
