New preprint suggests that reported symptoms are not a reliable indicator of TB disease severity, and that the context in which someone is investigated for TB—self-presentation to a clinic vs active community screening—may be more informative 👇 medrxiv.org/content/10.64898/2026.07.10.26357755v1

Our new paper in @nathealth.nature.com shows that population-level #TB interventions are likely to have more meaningful impact on disease burden than interventions that only reach routinely diagnosed individuals or their households. www.nature.com/articles/s44... 1/7

Global impact and cost-effectiveness of tuberculosis interventions - Nature Health

Our analysis of #TB exposure and transmission patterns is now in @pnas.org. @petedodd24.bsky.social and I found a majority of TB transmission globally is attributable to contact with adult men, while contributions to transmission by age are more variable across regions. www.pnas.org/doi/10.1073/...

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. bit.ly/4nbV492
