The TBPodAuthor: Actnet
The TBPod is a podcast for clinicians and policymakers caring for patients with tuberculosis. The podcasts present discussions with expert clinicians, researchers, policymakers and advocates about their work in the field of tuberculosis. Tuberculosis remains one of the leading causes of death worldwide, and is an important contributor to morbidity among migrants arriving in Australia and New Zealand. There are around 1300 reported cases of TB in Australia each year, and a further 300 in New Zealand. Included in these figures are cases of multi-drug resistant (MDR) TB which pose significant barriers to treatment and management of the disease. The Australian government has committed to the global elimination of TB by 2030, but to do so requires the development of innovative new strategies, based on high-quality research, that has national and international reach. These podcasts aim to engage and update those who are interested in the field of tuberculosis through discussions with leaders in the field of tuberculosis.

TB Origins – Dr Alice Sawka: Where Does the 8-Hour Contact Tracing Rule Come From?
Monday, 24 August, 2026
Dr Alice Sawka is joined by Dr Jack Callum, respiratory physician in London, and Dr Victoria Gray, infectious diseases physician in Brisbane, to explore the origins of the widely used “eight-hour rule” in TB contact tracing.Together, they examine the evidence behind this commonly used threshold, trace its roots to early studies of TB transmission during air travel, and discuss how clinicians and public health teams assess exposure risk. They also explore the practical challenges of contact tracing and the “stone in the pond” approach used to identify those at greatest risk of TB infection.This episode is the second in the TB Origins series, exploring the evidence and history behind long-standing TB clinical practices.Show NotesTuberculosis and air travel: guidelines for prevention and control – 3rd ed. “WHO/HTM/TB/2008.399” Available at: https://www.who.int/publications/i/item/9789241547505Driver CR, Valway SE, Morgan WM, Onorato IM, Castro KG.
