RT Journal Article T1 Interactions between hosts affect virus competition mechanism within an infectious strain A1 López Pedrares, Javier A1 Vázquez Cendón, María Elena A1 Pérez Muñuzuri, Alberto K1 Competition model K1 Epidemiological model K1 Ordinary differential equations K1 Virus K1 Pandemic K1 Complex network AB Competition of different viruses in a common strain usually results in one variant dominating over all others and eventually suppressing them, following the Principle of Competitive Exclusion. Viruses host in larger animals and they spread to others via the interactions between the hosts. In the present communication, we focus on the role played by the interacting hosts in determining the evolutionary path of a strain. Simple mathematical models are considered to model the evolution of the strain as well as to model the spread of the disease. We observe that the structure of the interactions between hosts influences the evolutionary mechanism as well as the spread of the disease PB Elsevier YR 2023 FD 2023 LK http://hdl.handle.net/10347/30623 UL http://hdl.handle.net/10347/30623 LA eng NO Chaos, Solitons & Fractals 170 (2023) 113344 NO We gratefully acknowledge financial support by the Spanish Ministerio de Economía y Competitividad and European Regional Development Fund under contract RTI2018-097063-B-I00 AEI/FEDER, UE, and by Xunta de Galicia under Research Grant No. 2021-PG036.
