Here, we extend the Movement–Interaction–Return metapopulation framework to explicitly include contagions acquired during transit, considering agents traveling along shared transportation networks. We reveal that incorporating in itinere contagion entails a notable reduction of the epidemic threshold and a pronounced delocalization of the epidemic trajectory, particularly significant in early-stage outbreaks. info:eu-repo/grantAgreement/ES/MICINN/JDC2022-048339-I info:eu-repo/grantAgreement/ES/MICINN/PID2021-128005NB-C21 info:eu-repo/grantAgreement/ES/MICINN/PID2023-147734NB-I00 info:eu-repo/grantAgreement/ES/MINECO/PID2020-113582GB-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Valgañón, Pablo Universidad de Zaragoza (orcid)0000-0003-2547-4547 Soriano-Paños, David (orcid)0000-0002-6388-4056 Gómez-Gardeñes, Jesús Universidad de Zaragoza (orcid)0000-0001-5204-1937 2003 395 Universidad de Zaragoza Dpto.
