Transmission of multiple pathogens across species

TL;DR

This paper models how multiple pathogens spread across various species, using branching processes to estimate outbreak probabilities, with specific focus on aquatic environments involving two host species and pathogens.

Contribution

It introduces a model for multi-pathogen, multi-species transmission and provides analytical and computational analysis for aquatic environment scenarios.

Findings

Branching process approximation effectively estimates outbreak probabilities.

Analytical solutions are derived for specific aquatic environment cases.

Computational results support the analytical findings.

Abstract

We analyse a model that describes the propagation of many pathogens within and between many species. A branching process approximation is used to compute the probability of disease outbreaks. Special cases of aquatic environments with two host species and one or two pathogens are considered both analytically and computationally.
