Tuberculosis, also abbreviated TB, is an infectious disease caused by several types of mycobacteria, specially the mycobacterium tuberculosis that most often - but not always - affect the lungs causing pulmonary tuberculosis.

TB can be transmitted from person to person through the air. If the infection spreads beyond the lungs, the symptoms will be determined by the organs affected.

Most cases are asymptomatic.TB get worse in people with compromised or weak immune system.

There are two types of TB:

- Latent TB, which means people have the bacteria but not symptoms and do not transmit the disease.

- Active TB, where the symptoms are manifested. First months they can be mild and not easy to recognize without tests. Patients can die if not treated. Cough with sputum and/or blood is typical of lung TB.


Diagnosis of TB is based on chest X-rays and microbiological tests. It is particularly difficult to diagnose in children.
