Before revision:  The study reveals that very close to the critical point, the critical slowing-down  phenomenon, introduced by the theory of critical phenomena, emerges ; additionally, a behavior of the epidemic obeying to a second order phase transition  occurs.
After revision:  The study reveals that very close to the critical point, the critical slowing-down phenomenon, introduced by the theory of critical phenomena, emerges , leading to a tremendous increase of both the percentage of active carriers and the duration of the epidemic. A behavior of the epidemic obeying to a second order phase transition occurs.
