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.
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.
