Figure 6. Snapshot of the exposed population.

The model indicates that there is an increased volatility in the exposed population after 200 days, due to the outgoing moves from the exposed population to the infectious population (Figure 6A), and an increased volatility in the infectious population after 240 days, due to the outgoing moves from the infectious population to the recovery population (Figure 7A). The spread of the disease in the discrete transform reached a peak at 70 days due to the large coefficients (Figure 6B). In the continuous wavelet transform at 72 days, there were no exposed individuals (Figure 6C) because they moved to the infectious stage.
