A particular case of interest for disease control is the emergence of discontinuous transitions in epidemic dynamics coming from their interactions with other simultaneous processes. To address this problem, here we propose a framework coupling a standard epidemic dynamics with another contagion process, presenting a tunable parameter shaping the nature of its transitions. Our model retrieves well-known results in the literature, such as the existence of first-order transitions arising from the mutual cooperation of epidemics or the onset of abrupt transitions when social contagions unidirectionally drive epidemics. We also reveal that negative feedback loops between simultaneous dynamical processes might suppress abrupt phenomena, thus increasing systems robustness against external perturbations. Our results render a general perspective toward finding different pathways to abrupt phenomena from the interaction of contagion processes. info:eu-repo/grantAgreement/ES/DGA/E36-23R-FENOL info:eu-repo/grantAgreement/ES/MICINN/PID2020-113582GB-I00 info:eu-repo/semantics/openAccess by https://creativecommons.org/licenses/by/4.0/deed.es 1.9 2024 0.641 2024 Artificial Intelligence 2024 Q2 Information Systems 2024 Q2 Computer Science Applications 2024 Q2 Computer Networks and Communications 2024 Q2 4.7 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Gómez-Gardeñes, Jesús Universidad de Zaragoza (orcid)0000-0001-5204-1937 Soriano-Paños, David 2003 395 Universidad de Zaragoza Dpto.
