[OCCUPATIONAL PREVALENCE OF MYCOBACTERIUM TUBERCULOSIS INFECTION AMONG HEALTHCARE WORKERS].

UNLABELLED: Professional prevalence of tuberculosis of workers of health care is the important medico-social problem.

MATERIALS AND

METHODS

The study is based on the observation of the epidemic process of tuberculosis in the Omsk region for 2000-2014. Material for the study was the data of the forms of Federal statistical observation. There were used observational descriptive and evaluative research methods of the study.
