The world is currently facing a global pandemic, unlike any seen in our lifetime. Yet organisations the world over have encountered something similar for many years.

AKQAs Sam Sterling spoke to mathematician Dr Adam Kucharski, Associate Professor at the London School of Hygiene & Tropical Medicine, where he works on outbreak analysis. Kucharski is a TED Senior Fellow and author of the book The Rules of Contagion: Why Things Spread and Why They Stop. He’s also a doctor but not the medical kind, which makes him ideally placed to discuss the characteristics of a virus in structural rather than biological terms.
