My first PhD project is finally a paper! 🎉🥹 In 2020, we paused this work to respond to COVID-19. But as mobile phone data became largely available and key to disease modeling, that detour provided the perfect context for this paper. @bansallab.bsky.social @stefania Rubrichi @vcolizza.bsky.social

A study of 25 primary schools in France found that weekly screening of all students during the Delta and Omicron waves of the COVID-19 pandemic reduced school transmission by around 40% compared to reactive strategies used at other schools. In PNAS Nexus: https://ow.ly/jhii50YCrcm

In this study, we systematically evaluate synthetic and empirical age-stratified contact matrices in France from March 2020 to May 2022, comparing contact patterns and their ability to reproduce observed epidemic dynamics.
Show PostWhile both sources captured similar temporal trends in contacts, empirical matrices recorded 3.4 times more contacts for individuals under 19 than synthetic matrices during school-open periods.
Show PostThe model using synthetic matrices provided the best fit to hospital and serological data. The weekly update of synthetic matrices enabled smoother reconstructions of hospitalization trends during transitional phases, while empirical matrices required strong assumptions between survey waves.
