Dynamics of changes in the number of relapses of tuberculosis in Republic of Tajikistan

Aim . To study the dynamics of changes in the registration of cases of tuberculosis and the frequency of recurrence of the disease in the Republic of Tajikistan between 2011-2020. Material and methods . The work is based on an analysis of official statistics of TB cases between 2010-2020 (National TB register). Results and discussion . Analysis of official statistics for the last 11 years has shown a steady decline in the number of registered TB cases. Thus, this indicator decreased from 7641 cases in 2010 to 4315 in 2020. A deeper analysis of the structure of registered TB cases shows that this decrease is mainly due to a decrease in the number of new TB cases. The dynamics of detection of relapses and repeated cases of the disease over this period were chaotic: either increased sharply or tended to decrease. It should be noted that the dynamics of the decrease in the number of registered TB cases over the 11 years had a similar trend with the number of cases of TB susceptible to anti-TB drugs, while the dynamics of changes in the number of TB cases with resistance to mycobacterium TB also had a chaotic character. Conclusion . An analysis of official statistics over the past 11 years has shown a steady decline in the number of registered TB cases, which is mainly due to a decrease in the number of new TB cases with preserved sensitivity to anti-TB drugs. An analysis of the dynamics of changes in the number of relapses after successful treatment of TB over the past 11 years showed that relapses of the disease are recorded annually in 4.16% and up to 12.9% of the total number of registered TB cases. There are regional differences in incidence and relapse from TB.
