Figure 1

A schematic representation of the mathematical model. The variables x and y are the number of target and infected cells; v I and v NI are the number of RNA copies of infectious and non-infectious virus, respectively. Parameters d, a, r RNA , and β represent the death rate of target cells, the death rate of infected cells, the degradation rate of viral RNA, and the rate constant for infection of cells by infectious virus, respectively. It is assumed that infected cells release virus particles at a rate k, that a fraction p of these particles are infectious (1-p are non-infectious) but lose infectivity at a rate r I , becoming non-infectious.
