As expected from the theory of critical phenomena, in the case of initial virus densities ρ below the critical value, time durations of the epidemic spread become significantly small. As already discussed, the proposed self-organized model seems to demonstrate a noteworthy behavior for a virus density equal to its critical value ρc, due to the CSD phenomenon, further leading to spectacularly increased relaxation times (high durations of the epidemic).	./cache/cord-212761-4bwatc2r.txt	./txt/cord-212761-4bwatc2r.txt
