SISD model

Susceptible-Infected-Susceptible-Deceased model (SISD) (wiki)

Usage

ModelSISD(name, prevalence, transmission_rate, recovery_rate, death_rate)

# S3 method for epiworld_sisd
plot(x, main = get_name(x), ...)

Arguments

name

String. Name of the virus.

prevalence

Double. Initial proportion of individuals with the virus.

transmission_rate

Numeric scalar between 0 and 1. Virus's rate of infection.

recovery_rate

Numeric scalar between 0 and 1. Rate of recovery from virus.

death_rate

Numeric scalar between 0 and 1. Rate of death from virus.

x

Object of class SISD.

main

Title of the plot.

...

Currently ignore.

Value

• The ModelSISD function returns a model of class epiworld_model.

• The plot function returns a plot of the SISD model of class epiworld_model.
