These models have been continuously refined to incorporate all the realistic mechanisms that can shape the course of an epidemic outbreak. Building on a compartmental model that accounts for early detection and isolation of infectious individuals through testing, in this article we focus on the viability of detection processes under limited availability of testing resources, and we study how the latter impacts on the detection rate. Our results show that, in addition to the well-known epidemic transition at R0=1, a second transition occurs at R★0>1 pinpointing the collapse of the detection system and, as a consequence, the switch from a regime of mitigation to a regime in which the pathogen spreads freely. We characterize the epidemic phase diagram of the model as a function of the relevant control parameters: the basic reproduction number, the maximum detection capacity of the system, and the fraction of individuals in shelter. Our analysis thus provides a valuable tool for estimating the detection resources and the level of confinement needed to face epidemic outbreaks. info:eu-repo/grantAgreement/ES/DGA/E36-23R-FENOL info:eu-repo/grantAgreement/ES/MICINN/PID2020-113582GB-I00 info:eu-repo/semantics/openAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 2.2 2023 PHYSICS, MATHEMATICAL 12 / 60 = 0.2 2023 Q1 T1 PHYSICS, FLUIDS & PLASMAS 17 / 40 = 0.425 2023 Q2 T2 0.805 2023 Condensed Matter Physics 2023 Q1 Statistics and Probability 2023 Q2 Statistical and Nonlinear Physics 2023 Q2 4.5 2023 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Reyna-Lara, Adriana Soriano-Paños, David (orcid)0000-0002-6388-4056 Latora, Vito Gómez-Gardeñes, Jesús Universidad de Zaragoza (orcid)0000-0001-5204-1937 2003 395 Universidad de Zaragoza Dpto.
