Detailed explanation-1: -The discovery of the bacteria proved that TB was an infectious disease, not hereditary. In 1905, Koch won the Nobel Prize for Medicine and Physiology. Today, we know TB is an airborne infectious disease, spread when a person with TB disease coughs, speaks, or sings.
Detailed explanation-2: -The famous scientist Robert Koch was able to isolate the tubercle bacillus and presented this extraordinary result to the society of Physiology in Berlin on 24 March 1882.
Detailed explanation-3: -TB that affects the lungs (pulmonary TB) is the most contagious type, but it usually only spreads after prolonged exposure to someone with the illness. In most healthy people, the body’s natural defence against infection and illness (the immune system) kills the bacteria and there are no symptoms.
Detailed explanation-4: -The tubercle bacillus discovered by Robert Koch in 1882 was termed Mycobacterium tuberculosis in 1886.
Detailed explanation-5: -A person with latent TB infection (LTBI) cannot spread the bacteria to others right away. Only those who develop active TB disease can spread the bacteria to others.
