spatio-temporal pattern of tuberculosis in the regions super-vised by shiraz university of medical sciences 2006-2012

background: the present study aimed to identify the spatial distribution of tuberculosis and determine the tb control program parameters in the regions supervised by shiraz university of medical sciences in 2006-2012. methods: the present ecological study was performed on 1797 tb patients in shiraz university in 2006-2012 which were recorded by health centers using tb register software. the study data were collected through over-counting and analyzed using the spss statistical software (ver. 19). besides, the maps were drawn by arcgis, version 10. results: the incidence rate of tb was 4.8 in 100,000 at the end of 2012. success in treatment was adequate only in 2012 (89.7%). however, recovery of pulmonary tb was not adequate in any of the study years. in our study, the majority of the patients belonged to the 25-34 years age group that constitutes the active faction of the society.  moreover, the maps provided by gis showed a high incidence rate of extra pulmonary tb in firozabad township during 7 years (2.7 in 100000 populations). conclusion: incidence of tb in the regions supervised by shiraz university of medical sciences follows a specific pattern, which requires exclusive studies for further evaluation of the incidence determinatives in various environmental and social conditions.
