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. 000133120 536__ $$9info:eu-repo/grantAgreement/ES/DGA/E36-23R-FENOL$$9info:eu-repo/grantAgreement/ES/MICINN/PID2020-113582GB-I00 000133120 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000133120 592__ $$a0.641$$b2024 000133120 593__ $$aArtificial Intelligence$$c2024$$dQ2 000133120 593__ $$aInformation Systems$$c2024$$dQ2 000133120 593__ $$aComputer Science Applications$$c2024$$dQ2 000133120 593__ $$aComputer Networks and Communications$$c2024$$dQ2 000133120 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000133120 700__ $$0(orcid)0000-0001-5204-1937$$aGómez-Gardeñes, Jesús$$uUniversidad de Zaragoza 000133120 700__ $$aSoriano-Paños, David 000133120 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDpto.
