Paolo Bajardi, Alain Barrat, Fabrizio Natale, Lara Savini, Vittoria, Colizza

TL;DR
This study uses network science to analyze daily cattle movement data in Italy, revealing dynamic patterns and vulnerabilities crucial for disease prevention, which are hidden in static analyses.
Contribution
It introduces a novel longitudinal analysis of cattle movements, uncovering dynamic motifs and temporal causality patterns that improve understanding of disease spread risks.
Findings
Stationarity of distributions coexists with dynamic evolution.
Static network views miss important structural changes.
Longitudinal analysis enhances intervention strategies.
Abstract
Despite their importance for the spread of zoonotic diseases, our understanding of the dynamical aspects characterizing the movements of farmed animal populations remains limited as these systems are traditionally studied as static objects and through simplified approximations. By leveraging on the network science approach, here we are able for the first time to fully analyze the longitudinal dataset of Italian cattle movements that reports the mobility of individual animals among farms on a daily basis. The complexity and inter-relations between topology, function and dynamical nature of the system are characterized at different spatial and time resolutions, in order to uncover patterns and vulnerabilities fundamental for the definition of targeted prevention and control measures for zoonotic diseases. Results show how the stationarity of statistical distributions coexists with a…
