The result of individual-based model is shown in figure 3. The dynamic behavior of the epidemic shows similar pattern as in figure 2, but different number of infected nodes and the length of time that reach to the maximum number of infected nodes. The period of time that infected nodes increase to the maximum are longer than the results from the first infected at villages under same transmission probability. For clearly comparison, we compared the straight line or the slope that before approach to steady state in figure 2(B) with figure 3(B) for Tv = 6-8 days, because the
