Epidemiological situation of brucellosis in Iran

Background and Aim: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 populationMethods:The required information has been gathering from the summary of patient information forms which are sent monthly through provincial health centers. In Our country 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: By studing the disease over the past 17 years, since2001 till 2017, It can be seen that the cases since2001 till 2009 from25 cases in hundred thousand people have been decreased to 18cases in hundred thousand people. Following the success of increasing vaccine coverage for livestock, the disease has been declining.From 2010 till 2014 from 17 cases in hundred thousand people has increased to 26 cases in hundred thousand people. The main reason for this increase is improving patient care and reporting, in addition to implemented policy changes in Animal vaccination during these years in order to raise vaccine coverage in population of mature and immature animals (Cattle, calves, sheep, goats, lambs and kids). The incidence of disease has been reduced from years of 2015to 2017 so that from 23 cases in hundred thousand people to 19 cases in hundred thousand people Which is in accordance with the brucellosis control program that includes developing and improving cross-sectoral coordination as the most important way of preventing and controlling human-animal transmissible diseases, the public education and high-risk groups using new educational methods such as the Shep model, training of doctors, veterinarians and staff as other strategies for the program over the past years. It has been seriously considered. Latest information on the disease shows that Hamedan, Lorestan , Kurdistan, Zanjan , Razavi Khorasan, Northern Khorasan West Azerbaijan, Ardebil, Kermanshah provinces had the highest incidence rate(incidence rate between 41-77 per 100,000) 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. Identify infected livestock foci - eligible animals vaccination - training at risk groups (farmers, herders, shepherds, slaughterhouse workers, butchers, housewives women in rural areas and laboratory staff) , using or not using pasteurized dairy products, development of pasteurized dairy production factories, are the main factors that will reduce or increase brucellosis.
