What is the characteristic of TB?

Tuberculosis (TB) is primarily characterized by its infectious nature, caused by the bacterium Mycobacterium tuberculosis. It commonly affects the lungs, leading to symptoms such as a persistent cough, chest pain, fever, night sweats, and weight loss. TB can be latent, where individuals carry the bacteria without showing symptoms, or active, where the disease manifests and can spread to others. Additionally, it is notable for its ability to develop resistance to antibiotics, complicating treatment.
