    "abstract": "We analyze a mathematical model of the epizootic of Hantavirus in mice\npopulation, including the effect of species which compete with the host. We\nshow that the existence of the second species has an important consequence for\nthe prevalence of the infectious agent in the host. When the two mice species\nsurvive in the ecosystem, the competitive pressure of the second species may\nlead to reduction or complete elimination of the prevalence of infection. The\ntransition between the disappearance of the infection and its presence occurs\nat a critical value of the competitor\u0027s population, resembling a second order\nphase transition in a statistical system. The results provide a rigorous\nframework for the study of the impact of biodiversity in the propagation of\ninfectious diseases, and further lends itself to future experimental\nverification.",
