In science:

However, the mutation of other viruses into the virulent strain could appear in isolated areas where they are not introduced through direct contact.
Large Deviations for Processes in Random Environments with Jumps
The virulence of the external agents is measured by || ¯L(t)||1 (i.e., the sum rate of external infection).
Epidemic Spreading with External Agents
The bounds are based on the graph topology (in particular, diameter/conductance of appropriate subgraphs) and a lower bound Lmin (n) on the virulence (which can scale with the network size).
Epidemic Spreading with External Agents
Now, to complete our system description, we term the quantity || ¯L(t)||1 as the long-range virulence at time t, i.e., the power of the infection to spread through long-range contact.
Epidemic Spreading with External Agents
Upper Bounds for Specific Policies Our first main result is an upper-bound on the finish time (both in expectation and with high probability) of the homogeneous external virulence policy, or as we refer to it hereafter, the random spread policy, for a general graph G.
