	Natural mortality rate for humans.
	The disease transmission rate for humans, which is dependent on time.
	Progression rate of exposed individuals to the asymptomatic and symptomatic individuals.
	Rate of recovery for asymptomatic and symptomatic individuals, respectively.
	Rate of transfer from asymptomatic to symptomatic individuals.
	Disease induce death rate.
	The periodic rate at which individuals distance themselves from each other.
	Relative infectivity parameter for the symptomatic compared to the asymptomatic individuals.
