Equilibrium Analysis of a Yellow Fever Dynamical Model with Vaccination

Table 1

Description of the variables of the yellow fever model (1).

Variable	Biological meaning
	Density of susceptible humans
	Density of vaccinated humans
	Density of infected humans
	Density of recovered humans
	Density of total human population
	Density of uninfected mosquitoes
	Density of latent mosquitoes
	Density of infected mosquitoes
	Density of total mosquitoes population
	Density of uninfected aquatic forms
	Density of total aquatic forms

Those variables are called “aquatic” because mosquitoes spend the large period of their development history in the water [25].
