We consider the spread of an infectious disease in a heterogeneous environment modeled as a network of patches. We focus on the invasibility of the disease, as quantified by the corresponding value of an approximation to the network basic reproduction number, R
0 , and study how changes in the network structure affect the value of R0 . We provide a detailed analysis for two model networks, a star and a path, and discuss the changes to the corresponding network structure that yield the largest decrease in R0 . We develop both combinatorial and matrix analytic techniques, and we illustrate our theoretical results by simulations with the exact R0 . [ABSTRACT FROM AUTHOR]- Published
