"The ways in which the great plagues of the past and present have spread around the world remain only partly understood. Peter Haggett's research over the last thirty years has focused on mapping and modelling the paths by which epidemics spread through human communities. The Geographical Structure of Epidemics, presents an-accessible, and illustrated account of how environmental and geographical concepts can be used to enhance our knowledge of the origins and progress of epidemics, and sometimes to slow or halt their spread."--BOOK JACKET.
