Abstract
Objective: To analyze the epidemic situation of multidrug-resistant tuberculosis in 2019 and the incidence trends from 2013 to 2019 in the Belt and Road countries. Methods: The 145 countries that have signed cooperation documents of the Belt and Road Initiative with China were selected. Age-standardized incidence and prevalence rate of multidrug-resistant tuberculosis from the Global Burden of Disease Study were used to describe the epidemic situation of multidrug-resistant tuberculosis in 2019. The annual percentage changes of the age-standardized incidence rate were calculated to assess incidence trends of multidrug-resistant tuberculosis from 2013 to 2019. Results: In 2019, of the 145 countries, Somalia had the highest incidence rate (30.42 per 100 000) and prevalence rate (48.86 per 100 000) of multidrug-resistant tuberculosis, while Slovenia had the lowest incidence rate (0.01 per 100 000) and prevalence rate (0.01 per 100 000). The incidence trends of multidrug-resistant tuberculosis in six continents from 2013 to 2019 were as follows: multidrug-resistant tuberculosis incidence rates showed increasing trends in 14 countries (27.45%) and decreasing trends in 22 countries (43.14%) in Africa, showed increasing trends in 2 countries (18.18%) and decreasing trends in 3 countries (27.27%) in North America and showed increasing trends in 2 countries (5.41%) and decreasing trends in 23 countries (62.16%) in Asia. The increasing trends were observed in Europe, Oceania, and South America, but it was found that 26 countries (96.30%) in Europe, 2 countries (18.18%) in Oceania, and 1 country (12.50%) in South America had decreasing trends of multidrug-resistant tuberculosis incidence rates. Conclusion: Multidrug-resistant tuberculosis is endemic in 145 Belt and Road countries with the prevalence increasing year by year in some countries in central and southern Africa and decreasing in European countries except Ukraine.
