ResumoLyme disease is a bacterial disease of humans and domestic animals transmitted primarily through the bite of the deer tick, Ixodes dammini. Using the ARC/INFO geographic information system (GIS), the distribution of tick vectors can be associated simultaneously with a large number of environmental, biological and demographic factors. The Illinois GIS was used to study the associations of soil type, potential vegetation cover and distance from waterways with tick distributions, and to compare the dispersion patterns of tick-infested and uninfested deer in one northwestern Illinois county. Tick presence was associated with sandy soils, wooded vegetation, and proximity to rivers. Infested deer were clustered around an endemic focus I. dammini, while uninfested deer showed no such clustering. Changes in the spatial distribution of ticks over two years and likely sites for further establishment of ticks were also studied.
