Neuraminidase Inhibitors (NIs)	Adamantanes
When NIs are given, they are assumed to reduce the rate of viral production, p, from infected cells with efficacy εNI, with εNI = 1 corresponding to 100% effectiveness [2, 39]: $$p\Rightarrow \left(1-{\epsilon }_{\mathit{NI}}\right)p$$ (9)	When adamantane antiviral drugs are given, they are assumed to reduce the rate of cell infection, β, with efficacy εA [6]: $$\beta \Rightarrow \left(1-{\epsilon }_A\right)\beta$$ (10)
