FIG 1.
A simple mechanistic model describing influenza virus progression. A pool of target respiratory epithelial cells (T) are infected by a pool of free virus (V) described by a second-order rate constant β. Infected cells (I) shed virus at a production rate p. Free virus is cleared by a rate c, and infected cells are cleared by rate δ. Oseltamivir acts by inhibiting viral production from infected cells. INH, inhibition.
