Abstract
We introduce the concept of recovery in the Ising-based SI model developed by C. Crisostomo and C.M. Pin?ol in 2012. The spread of infection and recovery or removal within a population confined in a two-dimensional square lattice is investigated. Here, dipole spins up (+1) and down (-1) are used to denote the presence and absence of infection, respectively. Changing of states from susceptible to infected to recovered (S → I → R and −1 → +1 → −1) occurs in the same manner by which spins flip, as outlined in the Metropolis Algorithm. In the model, infection and recovery are associated with different temperatures, TI and TR. Qualitatively, simulation results agree with the deterministic SIR model. However, not all becomes infected. A fraction of the population remained in the susceptible state even after the infection has died out.
