[Big data analysis of flow of tuberculosis cases in China, 2014]
1Public Health Surveillance and Information Service Center, Chinese Center for Disease Control and Prevention, Beijing 102206, China.
Objective:
To describe the flow of tuberculosis(TB)cases for medical care in China in 2014.
Methods:
The analysis and visualization of reported flow of TB cases were conducted with software R to indicate the case distribution/flow and the levels of hospital where TB cases sought medical care in different provinces.
Results:
In a province, the TB cases mainly flowed to the province capital, but the inter-provincial flow was mainly to neighbor provinces and from central or western provinces to eastern provinces(municipality), such as Beijing, Shanghai and Guangdong. The grade Ⅲ(A)hospitals were the choice of most TB cases seeking medical care in other provinces.
Conclusion:
The epidemic situation of TB in China is still serious, and the flow of TB cases would facilitate the spread of the disease. It is necessary to strengthen the research on influence of TB case flow for seeking medical care on the spread of TB to provide evidence for better TB prevention and control.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
