In EpiSimR: A 'Shiny' App to Simulate the Dynamics of Epidemic and Endemic Diseases Spread

EpiSimR

Overview

EpiSimR is an R Shiny application designed for simulating the dynamics of epidemic and endemic disease spread. It utilizes deterministic compartmental mathematical models to provide interactive visualizations and insights into disease transmission and control strategies.

Description

EpiSimR offers an interactive platform for modeling the spread of infectious diseases. Users can select different epidemiological models, including:

• SIR (Susceptible-Infectious-Recovered)
• SEIR (Susceptible-Exposed-Infectious-Recovered)

The app allows users to configure various parameters, such as:

• Inclusion or exclusion of permanent immunity
• Consideration of demographic changes
• Implementation of vaccination and isolation strategies

Users can adjust key epidemiological parameters, including:

• Basic reproduction number (R₀)
• Birth and mortality rates
• Infectious and latent periods
• Immunity duration
• Vaccination coverage
• Isolation rate

By modifying these parameters, users can simulate and visualize disease progression under different conditions and intervention strategies.

Installation

To install the package, use:

# Install from GitHub
devtools::install_github("NassimAyad87/EpiSimR", dependencies = TRUE)

Usage

Launch the Shiny application using:

library(EpiSimR)
run_app()
