Λ(x) | Recruitment rate of the susceptible host |
r(x) | Vaccination coverage rates of susceptible persons |
α(x) | Transmission between infected and vaccinated hosts |
β(x) | Transmission between infected and susceptible hosts |
\(d_{i}(x)\) (i = 1,2,3,4) | Mortality of susceptible, infected, vaccinated, and recovered hosts |
γ(x) | Recovery rate of infected persons |
K(x) | Half-saturation concentration |
η(x) | Effectiveness of vaccine |
