Incidence and Trends of Brucellosis in Azerbaijan from 2000 to 2024

Brucellosis, a zoonotic infectious disease, is a serious problem in Azerbaijan. Monitoring is essential for effective disease control. The objective of the study was to analyze the incidence rate and trends of brucellosis in Azerbaijan from 2000 to 2024. Incidence rates per 100,000 population were calculated and a trend analysis was conducted. The number of registered brucellosis cases decreased from 649 in 2000 (8.2 per 100,000) to 364 in 2010 (4.1 per 100,000). Between 2011 and 2020, incidence rates fluctuated, peaking in 2019 at 551 cases (5.5 per 100,000), with a sharp decline to 190 cases (1.9 per 100,000) in 2020. The decline continued between 2021 and 2024, with 210 cases (2.1 per 100,000) recorded in 2024. Despite a decline in brucellosis incidence in Azerbaijan over the past two decades, the disease remains endemic. Strengthened surveillance and preventive measures are needed to further reduce incidence.
