What we choose to implement - and when - matters. Our work shows that proactive screening strategies can reduce transmission by ~40% vs reactive responses. A key lesson for preparedness. In PNAS Nexus: ow.ly/cLnu50YCrcn

Great discussion with @billhanage.bsky.social and the audience at #ESCMIDGlobal2026 during our session “Pathogens and people: modelling epidemics for preparedness”. Strong focus on how to improve preparedness in collaboration with public health institutes - lots to take forward.

Mobility-based synthetic contact matrices offer a promising alternative for real-time pandemic response modeling. How do they compare with traditional empirical contact matrices?
We address this question in our latest study, now published in Nature Communications ⬇️

These results highlight the key role of spontaneous community-driven behaviour change, and the importance of risk communication and community engagement in outbreak control.
Model results aligned with post-outbreak survey data (ERAS 2023) reporting that ~46% of MSM reduced sexual partners during that outbreak.
Instead, the decline was best explained by widespread behavioural change, adopted by ~half of MSM, *independently of individual risk level*.
This prevented an estimated ~70% of potential cases during summer 2022.
We found that vaccination and infection-induced immunity alone could not explain the early downturn.
We used a network model of mpox transmission among MSM, grounded in sexual behaviour data, to disentangle the drivers: post-exposure vaccination, immunity among highly active individuals, behavioural adaptations.

Why did the 2022 mpox outbreak in Paris decline so abruptly?

Brilliant and inspiring talk by Shweta Bansal @bansallab.bsky.social at #Epidemics10 on contact patterns at the interface of data, modelling and public health — and even across species!
Many thanks to IReSP (Institut pour la Recherche en Santé Publique) and the Inserm Public Health Institute for the invitation to the Public Health Research Club #3. Proud to share #SUMOC perspectives on strengthening modeling in public health preparedness.
