Welcome to Litsy!

The human body is a marvel – but what happens when it comes under attack? A fascinating guide to why we get sick and how we get better. ‘Lovely, warm, erudite and, above all, chatty.’ Chris van Tulleken, author of Ultra Processed People Nature wants you dead. Not just you, but your children and everyone you have ever met and everyone they have ever met; in fact, everyone. It wants you to cough and sneeze and poop yourself into an early grave. It wants your blood vessels to burst and pustules to explode all over your body. And – until recently – it was really good at doing this… The subject of infection and how to fight it grows more urgent every day. How do pathogens cause disease? And what tools can we give our bodies to do battle? Infectious is not only a vital overview of what goes awry in our bodies, but also a hopeful story of ongoing human ingenuity.
