Impact on lethal outcome measures to identify and dispensary observation tuberculosis

When assessing and comparing the incidence of tuberculosis in different countries, it is necessary to take into account significant differences in the organization of identifying patients and establishing a diagnosis of tuberculosis. The true value of the indicator for incidence in any country of the world always differs from its recorded value. This difference, sometimes very significant, depends primarily on the efficiency of identifying TB patients, which varies not only in different countries, but even in individual regions within each of them.
