摘要:Factors such as booming population, environmental pollution, rapid urbanization, and global warming all influence the conditions for disease outbreaks. Disease studies have revealed strong spatial aspects, including disease case location and disease diffusion. Thus, mapping spatial aspects of diseases could help people understand some puzzles of disease outbreak. Geographical Information Systems (GIS) provide an effective way of managing, storing, analyzing, and mapping disease information. GIS has strong capabilities in mapping and analyzing not only spatial data, but also non-spatial data, and can integrate many kinds of data to greatly enhance disease surveillance. This paper deals with the preparation of Acute Gastroenteritis incidence distribution maps based on population density that would constitute a useful tool for disease control and for the health planners of Coimbatore district of Tamilnadu. The Acute gastroenteritis incidence data was collected from the Deputy Directorate of Health services, Coimbatore district for the period (2000-2009). The data was imported into ArcGIS 10.0. The mean Acute gastroenteritis incidences of Coimbatore district were used for the preparation of the thematic maps. For the present study, Natural breaks classification was used to classify the Acute gastroenteritis incidences data for thematic mapping. Mettupalayam predominantly remains a high incidence area from 2000 to 2009. From the year 2003 onwards and upto 2009, Avinashi and Coimbatore North taluks have consistently shown high incidences. Two village panchayats Irumbarai and Ikkaraiboluvampatti are at high risk which has an Acute Gastroenteritis incidence rate of more than 1; whereas the villages Maruthur and Coimbatore corporation have an incidence rate between 0.5 and 1 and the incidence rate below 0.5 is observed in ninety six villages. The risk map clearly visualizes the regions where efforts to control Acute Gastroenteritis have to be concentrated.
