Abstract

Brucellosis is a zeonosis and endemic disease in Iran, for accurate planning to control and eradicate the disease, it is necessary to study and investigate the epidemiological conditions of the region. The present study was carried out with the aim of investigating the epidemiology of brucellosis in the human and livestock populations of the Khorasan region (Iran). In this descriptive cross-sectional study, all studies related to human and animal brucellosis in three provinces of Khorasan region were reviewed. The results show that the prevalence of human brucellosis in the Khorasan region has increased significantly in recent years compared to a decade ago, with the prevalence of human brucellosis in Razavi, South and North Khorasan in 2009 being 25.41, 21.42 and 11.72 per 100,000 population respectively, reaching 78, 37 and 33 per 100,000 population respectively in 2020. Overall, the average prevalence of human brucellosis in the entire Khorasan region increased from 19.51 per 100 000 population in 2009 to 49 per 100 000 population in 2020. The prevalence of brucellosis in the region is also 0.56. % in cattle, 3.4% in small ruminants and 2.5% in horses. Epidemiological study of brucellosis in Khorasan region shows that the prevalence of brucellosis in the region is increasing, so the policy of brucellosis control should be reviewed and serious measures should be taken in this regard.
