Epidemiologic characteristics of new smear positive pulmonary tuberculosis in floating population in Chongqing between 2010 and 2017

Objective To analyze the characteristics of new smear positive pulmonary tuberculosis (PTB) in floating population in Chongqing, and provide evidence base for floating population TB control strategies development. Methods The population, geographical and time distribution of new smear positive PTB in floating population were analyzed based on the Chongqing TB management system 2010-2017. Results From 2010 to 2017, a total of 57740 cases of new smear positive PTB were registered in Chongqing, among which 2769 cases were from floating population, accounting for 4.8% (2769/57740) of total cases. The ratio of TB cases in floating population was significant increasing trend(χ2tend=408.430, P<0.01). For different age categories, most of them is 15-24 years age group in floating population. For sex distribution, male accounted for 64.8% (1793/2769), and female accounted for 35.2%(976/2769) in floating population. For occupational distribution, most cases were housekeepers 27.3%, farmers 22.1% and students 10.7%, and most students are in college and middle school. The proportion of new smear positive PTB cases was 69.2% (1916/2769) in total cases in the nine main districts of Chongqing, and among them, about 40.8% (1129/2769) in Shapingba, Jiulongpo and Nan’an districts. The registration of new smear positive PTB cases in floating population peaked from March to May and September. Conclusion To obtain the key population through analyzing the characteristics of new smear positive pulmonary tuberculosis(PTB) in floating population. It is significant in development of TB control strategies among floating population.
