In the case of pulmonary tuberculosis, the following symptoms may occur:
- A persistent cough (> 3 weeks)
- chest pain or difficulty breathing
- sputum (sometimes tinged with blood)
- night sweats
In the case of extra-pulmonary tuberculosis, the symptomatology depends on the affected organ.
The symptoms are sometimes unobtrusive or nonexistent, and the disease can go completely unnoticed; this can happen in children or adolescents, as well as in subjects whose immunity is impaired as in the elderly or those infected with HIV.
In the stage of latent tuberculosis infection, there are no symptoms!
