In SimInf: A Framework for Data-Driven Stochastic Disease Spread Simulations

Definition of the SIS model

Description

Class to handle the SIS SimInf_model.

Details

The SIS model contains two compartments; number of susceptible (S), and number of infectious (I). Moreover, it has two state transitions,

S -- beta S I / N --> I

I -- gamma I --> S

where β is the transmission rate, γ is the recovery rate, and N=S+I.

Examples

## Create an SIS model object.
model <- SIS(u0 = data.frame(S = 99, I = 1),
             tspan = 1:100,
             beta = 0.16,
             gamma = 0.077)

## Run the SIS model and plot the result.
set.seed(22)
result <- run(model)
plot(result)
