Global Health Security: Outbreak Spread Simulator

Interactive 3D simulation of an infectious outbreak spreading between countries through the international air-travel network, and how the speed of the global response changes the outcome.

Medicine & Biophysics3DModerate60 FPS

A local infectious cluster becomes a global emergency at the speed of the flights connecting the world, not the speed of any single country's healthcare system. This simulation places fourteen countries on a globe, links them through a simplified international air-travel network with a few dense aviation hubs, and runs a real coupled epidemic model across it. Pick a new outbreak, then adjust transmissibility, traffic volume and — most importantly — how quickly the international community reacts, to see why global health security is fundamentally a race against the network, not against any one border.

Interactive 3D simulation of an infectious outbreak spreading between fourteen countries through a simplified international air-travel network, showing how transmissibility, air-traffic volume and the speed of the global response together decide whether a local cluster stays contained or seeds a pandemic.
