Considerable effort is devoted to the development of geographical information systems (GIS) that increase understanding of public health problems and in particular to collaborate efforts among clinicians, epidemiologists, ecologists, and geographers to map and forecast disease risk.

Objectives: Small populations tend to give rise to the most extreme disease rates, even if the actual rates are similar across the areas.
