The Comparison of the effects of Climatic Elements in Cutaneous leishmaniosis incidence in two Gilan-e-Gharb and Kermanshah counties, between 2006-2016

weather conditions of each region play an important role in the dispersion of diseases; leishmaniosis dispersion is also affected by climatic elements. This disease in Iran also creates important health issues in some geographic areas of the country. Therefore, in this study, we make a comparison review of the effects and changes in temperature, precipitation and relative humidity, on the incidence of cutaneous leishmaniosis in two Gilan-e-Gharb and Kermanshah counties in Kermanshah province. This research is an applied one. Meteorological data related to temperature, precipitation and relative humidity variables have been collected from the Weather Administration of the province. Also, the data on the leishmaniosis disease during the statistical period of 2006-2016, were provided from Kermanshah Health Center. All statistical calculations were done using SPSS software, and the ARC GIS software being used to indicate infected areas.  The main purpose of this research is the Spatial-temporal analysis of cutaneous leishmaniosis in Kermanshah province; while, its sub-aims are to identify the main centers and the time course of the disease, and reviewing the relationship between climatic elements and of ' distribution in Kermanshah province. findings of this study showed that temperature, precipitation and relative humidity affects differently on the incidence of leishmaniosis disease in Gilan-e-Gharb and Kermanshah counties. In a way that in the city of Gilan-e-Gharb, temperature, precipitation and relative humidity affects the incidence of the factors of this disease. Such that there is a significant negative correlation between mean of minimum temperature and the incidence of disease with correlation coefficient (r = 0.246) at 99% level. But in Kermanshah, they have no effect on the disease appearance. Also, in case of the disease incidence process, it showed that these two cities are different in terms of the incidence of disease. Gilan-e-Gharb is a region wherein, the sandflies of the disease lives locally, while in Kermanshah it is not able to transmit the disease.resultantly, Climate changes and different seasons, affect on the growth and distribution of adult mosquitoes. This is why the of human infection pattern in the two cities of Gilan-e-Gharb and Kermanshah are different climatically.
