This work should not be seen as an attempt at comprehensive categorization of the role of meta-population structure on the dynamics of multi-strain diseases, but rather as an initial step in exploring the complex interplay between the population structure of hosts and strain structure of pathogens. Our results suggest there may be simple rules underlying this relationship, at least for a wide range of parameter values, but it remains to be seen where networks based on empirical data fall in these parameter regimes, as well as how such systems might deviate from theoretical expectations.
