Application of GIS and Modeling of Dengue Risk Areas in the Hawaiian Islands

摘要

Geographic analysis was conducted for the 2001-2002 Dengue Fever (DF) outbreak in the state of Hawaii. A GIS (Geographic Information System) spatial/temporal analysis depicting the spread of the disease and a spatial Dengue Threat Model (DTM) were created. In addition, GIS case clustering and mean/median distance comparison analysis of homes in rural and semi urban areas were conducted. The DTM is primarily a predictor of areas exhibiting the geographical, environmental, and epidemiological characteristics similar to East Maui where the majority of Dengue infection occurred. DTM output is derived via a weighted overlay analysis of the various datasets. This model may be adapted for use as a predictor in other arboviral (arthropod borne) outbreaks in various geographic locals.
