World's 25 per cent of tuberculosis patients are in India

India has the highest number of tuberculosis (TB) patients globally, about 25 percent of all cases.

While an urban tuberculosis case infects more individuals per year, a similar case in the rural area remains infectious for a longer period, according to the findings of a new research.

The Centre for Disease Dynamics, Economics and Policy (CDDEP) researchers have published their study in The International Journal of Tuberculosis and Lung Disease.The researchers of the new study have developed an approach to estimate the extent of TB in India using previous estimates from nearby countries and a current understanding of the TB transmission.
