The epidemiology of pandemic (H1N1) 2009 is not accurately known since it continues to spread across the world. The parameter values shown in Table 2 were chosen based on the best available data. The incubation period for pandemic (H1N1) 2009 has been reported to be 2-10 days with a mean of 6 days [18] . The mean time in the exposed classes E and E m corresponding to the incubation period has been assumed to be 6 days, making the transfer rate to the infectious classes, I and I m , constant at v = 1/6. The infectious period is believed to be between four and seven days, with an average of five days [19, 20] . Thus, the baseline value for the recovery rate is constant at d = 1/5. The fatality rate of the pandemic (H1N1) 2009 is thought to be in the range of 0.3%-1.5%, with a mean of 0.46% [21] [22] [23] . The case fatality rate for our model is m=(dzm), setting this equal to 0.0046 results in m~0:0046d=0:9954~0:001.
