Abstract : Models concerned with the spatial features of epidemic spread are often defined in terms of a nearest-neighbour grid network (Mollison and Kuulasmaa 1985). It is strongly conjectured, and can be proved in certain cases (eg Cox and Durrett 1988), that the infected area has (asymptotically) a well-defined shape. The present work concerns computer analysis of the shape of spread of a discrete-time single-parameter infection process on an eight neighbour lattice. Data from such simulations can be fitted with a particular group of three parameters which reveal features of the shape of the expanding epidemic.
