The Covid-19 pandemic is the most significant health emergency of our time.

Writing from Italy in lockdown, physicist and novelist Paolo Giordano explains how disease
spreads in our interconnected world:
why it matters
how it impacts us
how we must react
By expanding his focus to include other forms of contagion - from the environmental crisis to fake news and xenophobia - Giordano shows us not just how we got here but also how we can work together to move forward.
