The Covid-19 pandemic took the world by surprise, both through its virulence and the speed of its spread. A wealth of statistics, sometimes contradictory, has been published. Governments have introduced measures that often differ from one country to another. A range of medical treatments is being used. Can mathematics help us make the right decisions?

The current pandemic reminds us that mathematical models are built up in stages, from scientific assumptions and the available data. They are not objects in the real world, but abstractions. Their reliability can be established only by comparing them with reality.

What can epidemiological models contribute during a pandemic such as Covid-19? Can they justify measures that are difficult for the public by quantifying and explaining their direct effects on the spread of the disease?

Until very recently, mathematicians worked and published alone. Now, thanks in part to the development of modern communication tools, it is not uncommon to find research papers co-authored by more than four people. At Tim Gowers's instigation, several websites have enabled collaborative research.
