A global analysis of patterns of tuberculosis exposure and transmission Tuberculosis (TB) is a major public health concern and the leading infectious cause of mortality globally. The disease exhibits strong prevalence patterns by age and sex, but the implications of these...

Understanding patterns of #TB exposure and transmission is needed for targeted prevention strategies. In our latest pre-print, @petedodd24.bsky.social and I estimated the proportion of TB exposure to and transmission from sex and age groups for 177 countries.

Global, regional, and national estimates of tuberculosis incidence averted by eliminating undernutrition in adults: a modelling study Background Current efforts to reduce global tuberculosis incidence have proved insufficient, highlighting that urgent action is needed to address underlying modifiable risk factors such as undernutrit...

So...what would happen to the global TB epidemic if we hypothetically "eliminated" undernutrition? In this preprint, we combined estimates from our new review (doi.org/10.1093/ije/...) with population-specific BMI distributions to find out...(doi.org/10.1101/2025...)

Thinking fast and slow: the urgency of crisis response must not lead us to overlook chronic needs such as tuberculosis The number of people facing displacement due to humanitarian crises worldwide is increasing rapidly and is likely to continue.

In 2024, 68 million people were internally displaced by humanitarian crises, & are at increased risk of TB, the world's biggest infectious disease killer. We urgently need estimates to identify the scale of this problem & drive our response. We provide initial numbers here gh.bmj.com/content/10/3...

Tuberculosis treatment

Yes, #Tuberculosis (TB) is curable!

TB is treated with antibiotics taken daily for 4–6 months. ⚠️ Stopping treatment early can lead to drug-resistant TB.

Funding cuts & rising drug resistance put the most vulnerable at risk. Sustained support is crucial to #EndTB 👉 bit.ly/4ilkK1h #WorldTBDay

Our tool can estimate extent to which misallocation of person time will result in spurious or optimistic estimates of intervention effects
