Abstract:

Objective To understand main trends of reported case number of tuberculosis (TB) in China from 2015 to 2019. Methods By using TB incident case data (clinical diagnosed and laboratory confirmed) reported and recorded in the National Infectious Disease Reporting and Management System between 2015 and 2019, to analyze the national TB reported incidence and mortality, and TB reported incidence in different provinces,TB reported case numbers in different sex, age groups, occupations and their respective proportions. Results In 2015, the TB reported incidence nationwide was 63.42/100000 (864015/1362470000) which decreased to 55.55/100000 (775764/1396540000) in 2019, 12.41% lower than that in 2015. From 2015 to 2018, the reported incidence of Xinjiang Autonomous Region ranked first among all provinces, which were 184.56/100000 (42413/22980000), 185.66/100000 (43816/2360000), 202.59/100000 (48581/23980000), and 304.90/100000 (74549/24450000). In 2019, the Tibet Autonomous Region became the province with the highest reported incidence which was 182.38/100000 (6274/3440000). In terms of the sex distribution of reported cases in 2015 and 2019, males accounted for 68.97% (595939/864015) and 68.83% (533981/775764) respectively; females accounted for 31.03% (268076/864015) and 31.17% (241783/775764) respectively. In terms of occupational distribution, the proportion of farmers was the highest in 2015-2019, accounting for 64.42% (556643/864015), 63.81% (533637/836236), 62.26% (520003/835193), 61.42% (505664/823342), 60.06% (465945/775764), respectively. Conclusion From 2015 to 2019, the TB reported incidence in China showed a steady downward trend. Attention should be paid to the prevention and control of TB in key occupations and regions such as farmers, Tibet and Xinjiang Autonomous Region.
