Catching Breath: The Making and Unmaking of Tuberculosis

The organism responsible, Mycobacterium tuberculosis, has had plenty of time to adapt to its chosen habitat—human lungs—and has learned through natural selection to be an almost perfect pathogen. Using our own immune cells as a Trojan Horse to aid its spread, it's come up with clever ways to avoid being killed by antibiotics. But patience has been its biggest lesson—it can enter into a latent state when times are tough, only to come back to life when a host's immune system is compromised. Today, more than one million people die of the disease every year and around one-third of the world's population are believed to be infected. That's more than two billion people. Throw in the compounding problems of drug resistance, the HIV epidemic, and poverty, and it's clear that tuberculosis remains one of the most serious problems in world medicine.

Catching Breathfollows the history of TB through the ages, from its time as an infection of hunter-gatherers to the first human villages, which set it up with everything it needed to become the monstrous disease it is today, through to the perils of industrialization and urbanization. It goes on to look at the latest research in fighting the disease, with stories of modern scientific research, interviews with doctors on the TB frontline, and the personal experiences of those affected by the disease.
