Between 2011 and 2015, China reported 4.27 million TB cases, and 1.6 million were highly contagious.

Populations such as students and migrant workers are relatively susceptible due to their living environments, Wang added.

To curb the disease, the central government has earmarked 3.06 billion yuan ($471 million) in the past five years for TB control and prevention.
