The survivals of these bacteria in the environment have an important impact on the epidemiology of brucellosis worldwide. The effect of climate on the incidence of certain zoonotic infectious diseases, (recently referred to as climate-sensitive zoonosis) is now well established. The aim of this study was to evaluate the relation between the incidence of brucellosis and climatic parameters in Iran, an important endemic region for brucellosis with diverse climate. The information on the incidence of human brucellosis in different Iranian provinces for 2016 has been provided by the Ministry of Health and Medical Education, Iran. Annual meteorological data collected between 2015 and 2016 were obtained from the Iranian Meteorological organization (IMO). A regression analysis of the incidence of Brucella was performed via STATA 14.0 and the heterogeneity among observations was determined via Cochrane's Q-test and I2 statistic. If I2 index was higher than 50%, heterogeneity was considered as considerable. The results of our analysis revealed a negative significant association between mean ambient air temperature and brucellosis incidence (C = - 0.022, P value = 0.004). Likewise, a positive significant...
