Fig10
Figure 10 shows the solution tree returned by MCA for the Directed PCST problem. One of these outbreaks is the "giant" outbreak, shown in Fig. 10 as emanating from the leftmost child of the "dummy" root. There are four minor outbreaks, also shown in Fig. 10.

Fig11
In Fig. 11, we focus on another inferred asymptomatic case (node in blue in the highlighted portion of the tree) that may have spread the pathogen to its four child nodes (nodes in green).
Effect of  on the solution trees of the Directed PCST problem on UIHC data. Larger values of  lead to solutions with fewer infection cascades. Fewer infection cascades imply more transmission within the hospital and fewer cases imported from the community
