Tuberculosis

Almost one third of the entire world’s population is infected with Mycobacterium tuberculosis, the type of bacteria that causes TB. Although only a fraction of these people will actually become sick with the disease, in 2012, the World Health Organization reported 1.3 million TB related deaths.

The bad news is that TB is developing drug resistance. Learn more about this ancient disease, that still plagues us in the modern-day.
