Tuberculosis (TB) is a contagious and potentially fatal infectious disease that is caused by a bacteria called Mycobacterium tuberculosis. The disease primarily affects the lungs, but can also affect other parts of the body. TB was first identified in 1838 by German physician, Robert Koch, who named the illness after the Latin word tuberculum (meaning “swelling” or “lump”). The disease is spread through airborne droplets when an infected person coughs, sneezes, or talks.
What is TB?
TB is an infectious disease caused by a bacteria called Mycobacterium tuberculosis (MTB). The bacteria can spread through the air when an infected person coughs, sneezes, or talks, and can be passed on to other people if they come into contact with the droplets containing the bacteria. TB mainly affects the lungs, but it can also affect other parts of the body such as the brain, kidneys, and spine.
Why is TB Called Tuberculosis?
TB is called tuberculosis because it was first identified in 1838 by German physician, Robert Koch, who named the illness after the Latin word tuberculum (meaning “swelling” or “lump”). The name was chosen due to the swollen appearance of the lymph nodes on the neck of those infected with the disease, which is still seen in some cases today.
