TB disease is characterized by

• A. Shows symptoms and can spread to others
• B. No symptoms but can spread
• C. Only affects the skin
• D. Is non-communicable

Answer: (A)

Active TB disease is the active infection. When it’s active, the person usually has symptoms such as a persistent cough for weeks, coughing up blood or sputum, chest pain, fever, night sweats, and unintended weight loss. Because the bacteria spread through the air when someone with active TB coughs, talks, or sneezes, it can be transmitted to others, making TB disease contagious. This is different from latent TB infection, where the person has the bacteria but no symptoms and cannot spread it. TB does not only affect the skin; the most common form involves the lungs, and it is not non-communicable.
