Data were analyzed by SPSS software (Version 16.0).<br> <strong>Results:</strong> Totally, 4037 confirmed brucellosis cases were recorded, which the annual incidence of the disease was roughly decreasing during 2002-2009. The frequency of the illness in the male population was higher than that of women. Most cases were detected in summer and spring and occupational exposure had no significant impact on occurrence of the disease (<em>P</em> < 0.05).<br> <strong>Conclusion: </strong>The results of this study are greatly in line with the national pattern and other studies. Prohibition of consumption of uncontrolled traditional dairy products along with production of these products under hygienic conditions in modern industrial plants can prevent occurrences of human brucellosis.</span></span></div> Brucellosis, Incidence, Qazvin 45 48 http://jhehp.zums.ac.ir/browse.php?a_code=A-10-149-1&slc_lang=en&sid=1 Javad Abbasi jabbasi@alumni.ut.ac.ir 10031947532846009551 10031947532846009551 No Department of Health Sciences Research Centre, Torbat Heydaryieh University of Medical Sciences, Torbat Heydaryieh, Iran.
