25% of global TB cases in India: study

  • | Thursday | 23rd March, 2017

While urban TB infects more individuals per year, a rural TB case remains infectious for appreciably longer, suggesting the need for interventions tailored to these different settings. Tuberculosis (TB) infects more urban individuals per year while a similar case in rural area remains infectious for longer period, a new research has found. India bears the highest burden of TB globally, about 25% of all cases. “Results show differences in urban and rural TB. An urban TB case will infect an average of 12 people per year and remains infectious for about one year, while a rural case will infect an average of 4 people per year, but remains infectious for over two years.

India bears the highest burden of TB globally, about 25% of all cases. In a new study from the Centre for Disease Dynamics, Economics and Policy (CDDEP), researchers have developed an approach to estimate the extent of TB in India using previous estimates from nearby countries and a current understanding of TB transmission. The results of their study are published in The International Journal of Tuberculosis and Lung Disease. “Results show differences in urban and rural TB. While urban TB infects more individuals per year, a rural TB case remains infectious for appreciably longer, suggesting the need for interventions tailored to these different settings. “Simple models of TB transmission, in conjunction with necessary data, can offer approaches to burden estimation that complement those currently being used,” the study said. An urban TB case will infect an average of 12 people per year and remains infectious for about one year, while a rural case will infect an average of 4 people per year, but remains infectious for over two years.
