Infectious Disease Modeling Lab

Discrete compartment models for epidemiology teaching
Virtual epidemiology laboratory

Discrete-time models you can touch, test, and teach.

Launch SI, SIS, SIR, SEIR, SIRD, SEIRS, vector-borne, and age-structured simulations. Tune parameters, watch compartments evolve, compare outcomes, and translate equations into public health intuition.

A classroom-ready environment for asking "what happens if?" and immediately seeing the epidemiological consequence.

Model Dashboard

Select a discrete compartment model. Each model changes the equation set, visible compartments, interpretation text, and available outcomes.

SIR Model

Susceptible individuals become infected, then recover with immunity.
