Abstract
Introduction: Public health issues and spread of diseases have a direct relationship with the regional geography. The
present study was designed and conducted to determine spatial distribution of the incidence of malaria in the city of Jahrom, using Geographical Information System (GIS).
Materials and Methods: In the present descriptive study, the geographical longitude and latitude of each patient's place of residence was determined using Moran's spatial self-correlation method, and the disease incidence spots and risk using Kringing's interpolation technique and Jeefoo et al. classification in GIS-10.3.
Results: A total of 136 cases occurred over the study years, with the highest Annual Parasitic Incidence (API) in 2008, 2006 and 2007 (0.116, 0.115, and 0.108 per population of 1000 respectively) and since 2008, API has had a slightly fluctuating descending trend. The spatial analysis, Kringing interpolation and Jeefoo classification showed that Jahrom's suburbs have had a very high risk of incidence (0.275 per population of 1000), and Moran's spatial self-correlation showed that the disease was randomly distributed (Moran Index=0.04) (P=0.73) (Z-score=0.33).
Conclusion: The incidence of malaria was found to be higher in Jahrom's suburbs than other regions, and spatial
analysis showed that high risk regions can provide a useful malaria prevention and control planning tool.
