Epidemic manifestations of brucellosis in the safe area

Abstract

This report presents the epidemiological situation of brucellosis in the Ulyanovsk region. In the territory of the Ulyanovsk region brucellosis in humans for the first time was reported in 1950. For nearly forty years only chronic cases of brucellosis among the professional groups of population (breeders, veterinarians, meat processing plant personnel) were recorded, that confirms the professional nature of the disease. At the same time on a relatively calm background sporadic cases of brucellosis detected in both acute (1996), and subacute form (2005) in children are revealed. This confirms the position that the activity of the epidemic process in zoonotic infections is influenced by both biological (especially the pathogen and the immunological reactivity of human and animal), and social factors (the system of arrangement of epidemiological-epizootological supervision on the territory).
