EpiModel Gallery

A collection of template examples for extending EpiModel to model infectious disease dynamics over networks. Each example provides annotated code, pre-rendered output, and downloadable standalone scripts you can plug into your own projects.

If you’re new to writing custom EpiModel modules, we recommend starting with the two Fundamentals examples — Adding an Exposed State and SI with Vital Dynamics — which introduce the core patterns for custom compartments and vital dynamics. From there, the sidebar navigation follows a suggested learning sequence through intervention models (vaccination and test-and-treat), intermediate extensions like competing strains and social diffusion, full disease models (HIV and syphilis), and specialized topics like multilayer networks and cost-effectiveness analysis.

SEIR/SEIRS Model: Adding an Exposed State

Extend EpiModel’s SIR by adding a latent Exposed compartment, with an SEIRS waning-immunity extension.

SI Model with Age-Specific Vital Dynamics

vital dynamics

aging

beginner

An SI epidemic on a dynamic network with aging, births, and age-specific mortality using US life table data.

SEIR Model with All-or-Nothing Vaccination

SEIR epidemic model with all-or-nothing vaccination through three delivery routes — initial coverage, ongoing campaigns, and newborn vaccination — over a dynamic network…

SEIRS with Leaky Vaccination

Implements leaky vaccination where protection reduces (rather than eliminates) infection risk, on an SEIRS model with waning immunity and vital dynamics.

Test and Treat Intervention for an SIS Epidemic

An SIS epidemic model with a test-and-treat intervention for a bacterial STI, comparing screening intensities on a dynamic sexual contact network.

Competing Pathogen Strains in an SIS Epidemic

Models SIS with two competing strains differing in transmission-duration trade-offs, showing how network concurrency determines which strain dominates.
