Network Infectious Disease Modeling Lab

Transmission on random, small-world, and scale-free contact networks
Contact-network epidemic simulation

See how network structure changes outbreak risk.

Network models represent people as nodes and potentially infectious contacts as edges. Explore random mixing, small-world shortcuts, scale-free hubs, targeted vaccination, quarantine, and stochastic spread along connections.

The same transmission probability can behave differently on different graphs. Hubs, clustering, and shortcuts reshape the epidemic threshold.

Network Epidemic Simulator

Infection travels only along contact edges. Network topology controls who is reachable, how fast infection crosses communities, and whether hubs drive large outbreaks.
