Tuberculosis isn't a disease of the past. A fresh look at the global picture shows TB is still the number one cause of death from a single infectious agent worldwide. That means it claims more lives than any other single germ, like the ones that cause malaria or HIV/AIDS.

The report highlights a particularly vulnerable group: people living with HIV. For them, a TB infection is especially deadly. This underscores why fighting these two diseases together is so critical.

On a slightly brighter note, recent trends point to some modest progress toward global TB targets. But the report's main message is clear: this progress isn't enough. The authors state plainly that more focus and commitment is urgently needed to find, cure, and prevent TB everywhere. The data serves as a stark reminder that the fight against this ancient disease is far from over.

What this means for you:
TB is still the world's top infectious disease killer, especially for people with HIV.
