Tuberculosis has affected humans for millennia, with evidence of the disease found in ancient Egyptian mummies dating back to 3000 BCE. While once known as the "White Plague" and shrouded in mystery, the scientific discovery of the bacterium Mycobacterium tuberculosis by Robert Koch in 1882 transformed it from a perceived hereditary curse into a treatable infectious disease. How was Tuberculosis first identified and understood? In the 18th and 19th centuries, Tuberculosis was frequently misidentified as a hereditary condition due to its tendency to cluster in families.

History of Tuberculosis: when and how it was discovered, and the milestones in research since, medically reviewed.
Tuberculosis has affected humans for millennia, with evidence of the disease found in ancient Egyptian mummies dating back to 3000 BCE. While once known as the "White Plague" and shrouded in mystery, the scientific discovery of the bacterium Mycobacterium tuberculosis by Robert Koch in 1882 transformed it from a perceived hereditary curse into a treatable infectious disease.
How was Tuberculosis first identified and understood?
In the 18th and 19th centuries, Tuberculosis was frequently misidentified as a hereditary condition due to its tendency to cluster in families. Before the germ theory of disease, many believed it was caused by "miasma" or poor constitution. It wasn't until Robert Koch’s landmark 1882 presentation that the medical community confirmed Tuberculosis was caused by a specific pathogen, effectively debunking the myth that it was purely a genetic or lifestyle-related ailment.
What are the major milestones in Tuberculosis treatment?
The history of Tuberculosis treatment reflects the rapid advancement of modern medicine. Before the antibiotic era, the "sanatorium movement" was the primary intervention, focusing on fresh air and isolation. Key milestones include:
- 1882: Robert Koch identifies Mycobacterium tuberculosis.
- 1921: The BCG vaccine is first used in humans.
- 1943: Streptomycin is discovered by Selman Waksman, marking the first effective antibiotic treatment for Tuberculosis.
- 1952: Isoniazid is introduced, drastically improving survival rates.
How has the understanding of Tuberculosis evolved?
Modern clinical genomics has revolutionized our approach to Tuberculosis. Today, researchers use whole-genome sequencing to track the spread of drug-resistant strains. While Tuberculosis remains a global health challenge, with roughly 10.6 million people falling ill in 2022 according to the WHO, precision medicine allows for tailored treatment regimens that were unimaginable a century ago.
