Tuberculosis became a notifiable disease in 1902, and throughout history has been a major cause of mortality and morbidity in most communities around the world. 'It was like a leper's disease' was the response of an ex-tuberculosis sufferer when asked to describe his experience of having tuberculosis and the public's reaction to his illness. In the first half of the 20th century in Western Australia, the social consequences of tuberculosis were almost as confronting as the disease itself.

Also included are historical photographs and promotional materials from public health campaigns used by the Australian government.
