Morphological complexity brings an inherent heterogeneity in populations and affects the dynamics of pathogen spread in such systems.
Complexity and anisotropy in host morphology make populations safer against epidemic outbreaks
One of the main quantities involved in the SIR process is the transmissibility Tij defined as the probability that the pathogen is transmitted from an infected host at node i to infect a susceptible host located at node j during the life-time, τ , of the infected node.
Complexity and anisotropy in host morphology make populations safer against epidemic outbreaks
This broadening mimics the (diffusive) spreading of the pathogen around the host.

Studies show that pathogens not only are very modular but also that this modularity enhances their evolvability by allowing them to vary mutation rates between different parts of their genome.
The Emergence of Modularity in Biological Systems
It was also shown that bacteria occupying a limited number of niches have less modular metabolic networks than species occupying a greater variety of niches and pathogens that alternate between hosts have more modular metabolic networks than do single-host pathogens .
