Answer:
A cough from TB typically lasts more than 2 weeks, often accompanied by:

• Weight loss
• Night sweats
• Low-grade fever
• Loss of appetite
• Fatigue

TB is curable but requires proper diagnosis through chest X-ray and sputum testing. Anyone with a long-standing cough—especially those who live or work in crowded places—should get screened at their nearest health center.
