Someone can be a carrier of tuberculosis by being infected with the bacteria that causes the disease, Mycobacterium tuberculosis, but not showing any symptoms. This is known as latent tuberculosis infection. People with latent tuberculosis infection are not sick and cannot spread the disease to others, but they have the potential to develop active tuberculosis in the future if their immune system becomes weakened.
It is important to note that not everyone who is exposed to the bacteria that causes tuberculosis will become infected or develop the disease. Factors such as the strength of a person's immune system, overall health, and exposure to the bacteria can all play a role in whether or not someone becomes a carrier of tuberculosis.
Additionally, people with active tuberculosis can spread the disease to others through coughing, sneezing, or talking. If someone is in close contact with a person who has active tuberculosis, they may become infected with the bacteria and become a carrier themselves.
