Value

a numeric vector

Details

The dynamics of adult mosquitoes: $$\frac{dM}{dt} = \Lambda - \Omega \cdot M$$ The density of infected but not infectious mosquitoes: $$\frac{dY}{dt} = fq\kappa(M-Y) - \Omega \cdot Y$$ The density of infectious mosquitoes: $$\frac{dZ}{dt} = (Y-Z)/\tau - \Omega \cdot Z$$
