Note that the specific behavior of SkT Ã shown in Figure 3 results from the frequency dependence of SkT. When b I wb H , the network will reshape into a configuration with smaller SkT as soon as the disease expansion occurs. For tv1, SkT Ã reflects the lifetime of SS links, as there are hardly any infected in the population. For 10 0 vtv10 3 , the network dynamics proceeds fast enough to reduce SkT, but too slowly to reach its full potential in hindering disease progression. Given the higher fraction of infected, and the fact that SI and II links have a shorter lifetime than SS links, the average degree drops when increasing t from 1 to 10 3 . Any further increase in t leads to a higher average degree, as the network approaches its static limit.
