Abstract

We examine the invasion of a pathogenic fungus into populations of susceptibles. Combining epidemiological concepts with percolation theory we derive and test the following hypothesis: 1) fungal invasion into a population can be stopped by rendering a threshold proportion of the population immune for infection; 2) controlling infection at randomly selected sites introduces a shield which can prevent invasion of unprotected sites; 3) the rate of invasion reduces with increasing number of randomly protected sites. The significance of these findings is that the extent at which control strategies are applied spatially can be a critical component of disease management.
