, compared system (
) to the model without logistic term, the logistic term can cause transient oscillations to all populations at the beginning, and finally the model without logistic term may underestimate the number of the latently infected CD4
T-cells, productively infected CD4
T-cells, and infectious virions (b), (c), (d), while there is no too much difference with the number of healthy CD4
T-cells (a). For the parameters see the Data2 values of Table 1.
