Letter to the Editor

A Simple Analysis of Disease Foci. Scot C. Nelson, University of Hawaii at Manoa. Phytopathology 86:332-339. Accepted for publication 20 December 1995. Copyright The American Phytopathological Society, 1996. DOI: 10.1094/Phyto-86-332.

This letter was written to articulate a problem for nonepidemiologists, to propose a possible solution, and to discuss applications of the solution. The function of this letter is to advocate for simplicity in spatial data analysis, to describe a simple and effective alternative to more complex forms of analysis, and to encourage the study of epidemics as populations of disease foci rather than populations of diseased individuals.
