Medical, Differences in the Dynamics, Seasonality, and Risk Factors of Brucellosis Incidence in the City of Mailuu-Suu, Jalal-Abad Region (2020–2024)

This study presents a retrospective analysis of brucellosis incidence in the city of Mailuu-Suu and the Jalal-Abad Region of the Kyrgyz Republic for the period 2020–2024. The findings demonstrate that throughout the entire observation period, the incidence rates in Mailuu-Suu consistently exceeded the regional averages: city-level indicators ranged from 29.9 to 57.5 per 100,000 population, while regional rates varied from 18.7 to 25.2 per 100,000. The study also identified episodically high incidence among children under 14 years of age in the city (up to 51.9 per 100,000), along with a pronounced predominance of male cases (75% in the city versus 68.5% in the region). The seasonal pattern in Mailuu-Suu was characterized by a biphasic peak (in spring and autumn), whereas the region exhibited a classical summer–autumn seasonality typical of endemic rural territories. These findings underscore the high epidemiological significance of Mailuu-Suu and highlight the need for prioritized, targeted preventive measures and strengthened intersectoral collaboration.
