Infectious diseases are of the most fatal threats in human history. Some recent studies have investigated the way interacting diseases become epidemic. In this work we consider two pathogenes each having two different strategies: cooperation or defection. By analysing the fundamental properties of the interacting contagious processes a well-mixed population, i.e. homogenous mean field approximation, new discontinous phase transitions are discovered. For a deeper understanding the parameters are altered and the change in the steady state solutions described. Using stochastic simluations we find multistabilites and show the relationships between the defective and cooperative pathogens.This work aims to improve our understanding of the natural dynamics of species populations in an evolutionary ecological framework.
