Tuberculosis (TB) in the past also called phthisis, phthisis pulmonalis, or consumption, is a widespread, infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis.
China is the nation with highest incident cases among the Western pacific region(divisions made by WHO). Rate of TB incidence in China is 70 per 100 000 population. Every year as many as 9 80 000 people are newly diagonised of TB.
Tuberculosis prevention and control efforts primarily rely on the vaccination of infants and the detection and appropriate treatment of active cases. The only available vaccine as of 2011 is Bacillus Calmette-Guérin (BCG)
To encourage further discovery, researchers and policymakers are promoting new economic models of vaccine development, including prizes, tax incentives, and advance market commitments.
