Susceptible Infected Removed Deceased model (SIRD connected)

## Arguments

- name
String. Name of the virus

- n
Number of individuals in the population.

- prevalence
Double. Initial proportion of individuals with the virus.

- contact_rate
Numeric scalar. Average number of contacts per step.

- transmission_rate
Numeric scalar between 0 and 1. Probability of transmission.

- recovery_rate
Numeric scalar between 0 and 1. Probability of recovery.

- death_rate
Numeric scalar between 0 and 1. Probability of death.

- x
Object of class SIRDCONN.

- main
Title of the plot

- ...
Currently ignore.

## Value

The

`ModelSIRDCONN`

function returns a model of class epiworld_model.

The `plot`

function returns a plot of the SIRDCONN model of class
epiworld_model.

## Details

The initial_states function allows the user to set the initial state of the model. The user must provide a vector of proportions indicating the following values: (1) proportion of non-infected agents already removed, and (2) proportion of non-ifected agents already deceased.
