Abstract:

Objective To analyze the incidence trends and epidemic characteristics of pulmonary tuberculosis in Xishuangbanna from 2005 to 2018, so as to provide scientific basis for developing TB control strategies and measures. Methods Using infectious disease reporting information management system, a subsystem of China’s disease prevention and control information system to collect monitoring data, 12949 cases of pulmonary tuberculosis patients with cumulative reports from 2005 to 2018 were selected as the research objects. Descriptive statistical analysis method was used to analyze the distribution of onset time, region and population characteristics. Results A total of 12949 TB cases were reported from 2005 to 2018 in Xishuangbanna with an average annual newly reported incidence rate of 83.18/100000 (12949/15566693), the incidence declined from 89.44/100000 (926/1035276) in 2005 to 64.18/100000 (737/1148310) in 2014 and climbed to 117.12/100000 (1382/1180000) in 2018, which showed significant statistical difference ({\chi }_{\mathrm{trend}}^2=178.320,P<0.001). The peak incidence was reported in January (1315 cases) and the lowest in December (858 cases). The male average annual reported incidence rate of 109.46/100000 (8783/8024177), Whereas the female average annual reported incidence rate of 55.23/100000 (4166/7542516), which showed significant statistical difference (χ²=1375.344,P<0.001); Farmers accounted for the highest proportion of occupation (61.25%, 7931/12949), and the cumulative number of reported patients mainly concentrated in the age of 20-59, accounting for 72.06% (9331/12949). Conclusion The incidence of tuberculosis shows a rising trend in Xishuangbanna from 2005 to 2018, epidemic situation was serious, it is necessary to strengthen the TB prevention and control among the young adults, men and farmers.
