Abstract: 

Background: Brucellosis is one of the most common infectious diseases in Iran, Middle East and the vast areas worldwide. As Brucellosis is transmitted from animals to humans (Zoonoses), in addition to debility of patients and complications from disease and also economic losses caused by the disease control strategies in human population, leads to a reduction in food resources due to reduced animal population because of abortion in livestock and economic burden inflicted on the population.
Methods: The required information has been gathering from the summary of patient information forms, which are sent monthly through provincial health centers. In Iran epidemiological care strategies done by probable case definition, monthly case reports and if necessary, sentinel surveillance of high-risk groups, and annual and current reports indicate the disease process during several years and its influencing factors affects the increasing or decreasing disease trend.
Results: Over the last three decades studying the disease since1982 till 2013, It can be seen that the cases since1989 till 2001 from 175 cases in hundred thousand people have been decreased to 25 cases in hundred thousand people. From 2001 till 2005 from 25 cases in hundred thousand people has increased to 39 cases in hundred thousand people. The disease process has been reduced from years of 2005 to 2010 so that from 39 cases in hundred thousand people decrease to about 16 cases in hundred thousand people and in recent years the disease has increased from 2010 until 2013. According to the latest information on the disease in 2013 cases of disease were 19086 of which incidence is 25 cases in hundred thousand people. Hamedan, Lorestan, Kurdistan, West Azerbaijan, Kermanshah had the highest pollution (incidence rate between 84-54 per 100, 000). Maximum number of people is in the age group 15-24 years, the highest number of cases were in the spring and summer months and in rural areas (78%) more than the urban areas (22%) and for both sex men are (61 percent) and females (39 percent).
Conclusion: Increasing vaccination coverage in veterinary livestock sector and widespread deployment of pasteurization factories and producing pasteurized milk and products during these years has been the most important factors in reducing the incidence of the disease.
