However, despite of its importance for disease contagion, the directionality of edges has rarely been taken into account. On the other hand, the introduction of the multilayer framework has made it possible to deal with more complex scenarios in epidemiology such as the interaction between different pathogens or multiple strains of the same disease. In this work, we study in depth the dynamics of disease spreading in directed multilayer networks. Using the generating function approach and numerical simulations of a stochastic susceptible-infected-susceptible model, we calculate the epidemic threshold of synthetic and real-world multilayer systems and show that it is mainly determined by the directionality of the links connecting different layers, regardless of the degree distribution chosen for the layers. Our findings are of utmost interest given the ubiquitous presence of directed multilayer networks and the widespread use of disease-like spreading processes in abroad range of phenomena such as diffusion processes in social and transportation systems. info:eu-repo/grantAgreement/ES/MINECO/FIS2017-87519-P info:eu-repo/grantAgreement/ES/MINECO/FIS2014-55867-P info:eu-repo/grantAgreement/ES/DGA/E36-17R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 3.539 2019 PHYSICS, MULTIDISCIPLINARY 17 / 85 = 0.2 2019 Q1 T1 1.734 2019 Physics and Astronomy (miscellaneous) 2019 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-1192-8707 Aleta, Alberto Universidad de Zaragoza Lu, Dan (orcid)0000-0002-0895-1893 Moreno, Yamir Universidad de Zaragoza 2004 405 Universidad de Zaragoza Dpto.
