Symptoms of TB vary, depending on whether the disease is active or latent. Those with active TB generally exhibit these symptoms:

• A bad cough that lasts more than 2 weeks
• Coughing up blood or sputum from deep in the lungs
• Pain in the chest
• Weakness or fatigue
• Weight loss
• No appetite
• Chills/fever
• Night sweats

Those with latent TB may have no symptoms and do not feel sick. However, they will have a positive skin test with normal chest x-ray and sputum cultures.
