title: [Analyzing the epidemic situation due to tuberculosis and ways of optimization of its control in the penitentiary facilities of the Ulyanovsk Region].
abstract: The dynamics of epidemic parameters and the specific features of development of tuberculosis were analyzed in prisoners in 1989-2001. It was ascertained that 98.7% of them were infected with tuberculosis and most of them belonged to a tuberculosis high-risk group. In 67.5% of those who had fallen ill, the process was detected within the first 3 years of their confinement. A scheme of interaction of main propulsive forces of an epidemic process in tuberculosis (exogenous and endogenous infections and risk factors) is presented. It has been found that surveys for tuberculosis are not a deterrent for a rise in the incidence rates due to endogenous infection. The use of factorial analysis and systems approach in the epidemiology of tuberculosis has explained some regularities in the development of an epidemic process, revealed reasons for the aggravated tuberculosis situation in penitentiary institutions, and considered prospects for its improvement.
