(pp. 109258-).0025-5564https://mro.massey.ac.nz/handle/10179/71164We present a model for the dynamics of two interacting pathogen variants in a wild animal host population. Using the next-generation matrix approach we define the invasion threshold for one pathogen variant when the other is already established and at steady state. We then provide explicit criteria for the special cases where: i) the two pathogen variants exclude each other; ii) one variant excludes the other; iii) the population dynamics of hosts infected with both variants are independent of the order of infection; iv) there is no interaction between the variants; and v) one variant enhances transmission of the other.(c) 2024 The Author/sCC BY 4.0https://creativecommons.org/licenses/by/4.0/Basic reproduction numberEcologyEpidemiologyInteracting pathogen variantsInvasion thresholdsNext-generation matrixJournal article10.1016/j.mbs.2024.1092581879-3134journal-article109258-https://www.ncbi.nlm.nih.gov/pubmed/39004215109258S0025-5564(24)00118-4
