New paper in @plosmedicine.org led by @aportnoy.bsky.social builds on our analysis of the potential epidemiological impacts of reductions in donor funding for #TB to show the economic burden on affected individuals and their households.
In this modeling study, Allison Portnoy and colleagues investigate the potential impact of reduced international donor funding on the household economic burden of tuberculosis in low- and middle-income countries π§ͺ #MedSky #TB

Our recent modelling study found that the estimated impact of new TB vaccines depends on the efficacy to prevent infectious asymptomatic TB. Read more in our paper out now in @plosmedicine.org!

Really excited to share that this work from @aschwalbc.bsky.social estimating the burden of viable Mtb infection is now published in @plosmedicine.org!
Our new paper on strategies for implementing a potential new #TB #vaccine in South Africa is now published in @plosglobalpublichealth.org!

Another successful "Intro to TB Modelling" course in Copenhagen at #WLHC2025. Over 70 joined to learn about TB modelling!
Followed by the now-traditional TB Modelling and Analysis Consortium social, which was also very well-attended and a lot of fun.
All are welcome to join the Gender Equity in TB Working Group today at 12:30 in Room B4B @theunion.org! We'll share updates on working group activities and host a panel discussion on progress to date and ways forward to ensure an equitable and inclusive #TB response.
Day 1: the LIGHT Annual Consortium meeting kicks off this morning at the Crown Plaza in Copenhagen.
Consortium partners from Nigeria, Malawi, Kenya, Uganda and the UK meet to discuss the key research findings, research uptake and impact so far.
π¨Fully-funded PhD opportunity!π¨

Many thanks to @theunion.org and @the-independent.com for highlighting our work estimating the impact of reductions in global health funding on #TB morbidity and mortality

How will population shifts affect the future burden of #AMR? πΆπ©β𦳠π§«
We use a new modelling framework to explore future projections of #AMR by age and by sex, as well as interventions for control, building on our earlier findings that AMR isnβt uniform across demographics.

When fluoroquinolone resistance status is unknown, empirical use of BPaLM (adding moxifloxacin to BPaL) is cost-effective as a replacement for BPaL even with high fluoroquinolone resistance levels! π¦ π

Our framework that informed the @who.int TB & climate change policy brief out now in @lancetrespirmed.bsky.social, exploring the intersections and implications of climate change for the TB epidemic. Key message? TB should be considered a climate-sensitive disease

It was a real pleasure to deliver this Introduction to TB Modelling workshop for representatives from Kenyaβs National TB, Leprosy and Lung Disease Programme last week with great discussions about how modelling can be used in policy and programme decisions.
Our analysis highlights underappreciated patterns in #TB exposure and transmission that are directly relevant to efforts to end TB. More systematic analyses to understand the epidemiology of TB transmission should be used to inform context-specific prevention and care strategies.
Across age groups, TB exposure typically peaked in adolescence. However, transmission contributions by age varied across regions with the highest proportion from adolescents aged 15-24 in AMR and SEAR, adults aged 35-44 in AFR and EUR, and older adults 65+ in EMR and WPR.
[NOT YET PEER REVIEWED]
Both exposure and transmission were higher in males than in females. We found that a majority of TB transmission was attributable to contact with adult men: 67% (95% UI 62-71%) of transmission to men, 52% (95% UI 49-56%) to women, and 63% (95% UI 58-68%) to children.
[NOT YET PEER REVIEWED]
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.

In a new preprint (NOT PEER REVIEWED) we continue to explore the challenge of overtreatment in community screening. It seems the benefits of TB treatment far outweigh the harms, especially once we accept that sputum culture is not perfect. Important food for thought. www.medrxiv.org/content/10.1...

Our systematic review of rural/urban differences in #TB prevalence shows evidence of rapidly urbanising epidemics in many settings, with differences across countries and regions.

Sad (but not surprised) to read the latest Global Health 50/50 report, amidst turmoil in global health, erosion of democracy, withdrawal from multi-lateralism, aid cuts, attacks on science, DEI, human rights
@kentbuse.bsky.social @jocalynclark.bsky.social

Men are more than twice as likely as women to have prevalent #TB.
We did updated meta-analysis including over 4million people in 99 surveys.
Despite increasing focus on gender equitable TB responses, this gap has widened since we last assessed these data over a decade ago.
6/ @petermacp.bsky.social and I seem to be the only coauthors on Bluesky, but this work comes from a great team across @hsph.harvard.edu @uofglasgow.bsky.social @tb-lshtm.bsky.social @lshtm-tbmod.bsky.social
5/ These findings show that, despite calls for gender responsive TB prevention and care, disparities have increased over the past three decades. Effective strategies to reduce menβs risk of TB and to engage men in TB prevention and care remain essential to end TB.
NOT PEER REVIEWED
4/ The stability of pooled estimates doesn't mean sex ratios have remained consistent. We found evidence that male-to-female ratios likely increased 1.6% (95% CrI -1.0-6.2%) annually over the period 1994β2021, with the greatest increase in the Western Pacific region.
NOT PEER REVIEWED
3/ We fitted multi-level Bayesian regression models to estimate a pooled male-to-female prevalence ratio of 2.21 (95% CrI 1.94-2.50) for bacteriologically-confirmed TB.
That's the same point estimate as our previous review, but the two studies used different analytical methods.
