The variable \(Y\) is the density of infected mosquitoes. The model blood feeding parameters are:
\(f\) is the overall blood feeding rate
\(q\) is the human fraction for blood feeding
\(\Omega\) is the demographic matrix
\(\tau\) is the EIP
The net blood feeding rate by infectious mosquitoes is computed by accounting for survival and dispersal that would occur in a delay differential equation: $$\Upsilon = e^{-\Omega \tau}$$ so $$fqZ = fq (\Upsilon \cdot Y)$$ The daily EIR for the population strata is \(\beta \cdot fqZ\)
