3.5.3 Temporal network vulnerability and resilience
The size of the OCC (outgoing contact chain) was calculated for all nodes. In general, the removal of nodes based on degree, betweenness, and reverse PageRank resulted in greater decreases in the OCC sizes as compared to the removal of nodes based on PageRank or at random (Figure 5). The removal of only 10 nodes had a little impact regardless of how the removed nodes were selected. However, targeted removal of >250 highly connected nodes resulted in a noticeable decrease in OCC. Removal of just 250 nodes (2.15% of the total network) led to up to a 50% decrease in mean OCC when using degree as the targeting metric. The complete distribution values for each SNA parameter after each node removal were plotted (supplementary figure 1), and for visualization, the mean and confidence intervals are shown by week (Figure 5).
