This software allows you to model epidemics with general random distribution for the infectious period.
Traditional epidemiology models, like SIR, do not take into account the distribution for the length of the infectious period. In this software, we include three functions that compute these type of models using other distributions.
In this graph you can see how different the predictions are for the regular SIR model with respect to SIR-G that actually uses a more realistic distribution for the infectious period. In SIR-G case the peak of infection occurs before, and has a bigger intensity. The number of individuals that eventually get infected, however, remains the same for both models
- SIR: Classical SIR model, with (implied) exponential infectious period.
- SIR_G: Like the classical SIR model, but with an arbitrary distribution.
- SIR-PHG: A SIR model with Phase-Type distributions for the infectious period.
- SEIRD: A SEIRD Model with hase-Type distributions for each stage.
- The theoretical foundation of the method is explained in this paper.
