How TB is transmitted

Tuberculosis is a very contagious disease and easy to contract, but only when the bacteria affect the lungs. And, in many cases, it is difficult to establish prevention measures because tuberculosis bacteria are transmitted through the air from person to person.

In this way, when someone has tuberculosis and sneezes, spits, coughs or simply speaks, they are spreading the bacteria through the air, which enter another person's body through their breathing.

However, it is key to clarify that, if the affected person is undergoing treatment against tuberculosis, this disease is not transmitted through the air or by any other means. In general, there is also no risk of contagion when the bacteria are only in other parts of the body such as the kidneys, brain or spine, among other possible areas of the body where this bacterium is usually located.

To catch this disease, you only need to have inhaled a few bacteria. However, having breathed it and that it is in the body, does not imply that the disease develops. This is what is known as latent tuberculosis.
