Ph.D. student Ravi Batra (Public Health) and Kavita Batra (Medicine) co-authored a study published in The Lancet Infectious Diseases titled, "Global, regional, and national burden of tuberculosis and multidrug-resistant tuberculosis by HIV status, 1990-2023: a systematic analysis for the Global Burden of Disease Study 2023."

The study reports that in 2023, tuberculosis caused an estimated 9.11 million new cases, 1.22 million deaths, and 54.6 million disability-adjusted life years (DALYs) globally. While TB incidence and mortality have declined since 2015, progress against multidrug-resistant TB remains limited, with the highest burden concentrated in sub-Saharan Africa and South Asia. The findings also highlight that reducing modifiable risk factors such as smoking, alcohol use, and high fasting plasma glucose could substantially decrease the global TB burden.
