Tuberculosis Research

Tuberculosis (TB) accounts for approximately two million deaths worldwide each year and is the second greatest contributor among infectious diseases to adult mortality. The World Health Organization estimates that more than one-third of the world’s population is infected with Myobacterium tuberculosis (MTB) and more than eight million people with TB infection develop active TB disease each year. 

If left undiagnosed or untreated, an individual with TB disease may infect between 10 and 15 people each year. TB affects the most productive and economically active segment of the population: morbidity can result in 3-4 months of lost work time and a loss of 20% of annual household income. 

The GRA Partnership workplan reflects existing and proposed studies to address issues such as multi-drug resistant TB (MDR-TB), co-infection of TB and HIV, and other key areas of research for improving global TB control by promoting strategic research, scientific and programmatic innovation, leadership, and training in high-burden countries.
