Tuberculosis types and its characteristics in Dindigul District-A Geomedical study using GIS

Disease means without illness or discomfort. The term disease broadly refers to any condition that impairs normal function. Commonly this term is used to refer specially to infectious disease. Tuberculosis (TB) is an infectious disease that has plagued humans. Since the Neolithic times two organisms causes tuberculosis-Mycobacterium tuberculosis and Mycobacterium bovis. Physicians in ancient Greece called this illness “phthisis” to reflect is wasting character. Robert Koch isolated the tubercle bacillus in 1882 and established tuberculosis as an infectious disease. Tuberculosis disease is classified into three categoriespulmonary tuberculosis and extra pulmonary tuberculosis, Millary Tuberculosis. Pulmonary tuberculosis has a chronic infection of the lungs. Extra pulmonary tuberculosis occurs primarily in those with a compromised immune system. Millary Tuberculosis usually affects erosion of the infection to a Pulmonary Vein. The symptoms of tuberculosis depend on where in the body the tuberculosis bacteria are growing. Tuberculosis bacteria often grow in the lungs, causing pulmonary tuberculosis. Pulmonary tuberculosis may cause a bad cough that lasts longer than two weeks, pain in the chest and coughing up of blood or sputum. The main objectives are, to analyses the spatial distribution of the tuberculosis types in Dindigul and map out them. To study the disease pattern in relationship to case history and demographic characteristic dimensions. The study will be analysed based on secondary data. Factor analysis was used to identify the major dimensions of Tuberculosis treatments. GIS techniques were used for mapping of Tuberculosis types and characteristics for the study.
