A Cough That Won’t Go: When to Think About TB

Recognising the two-week threshold that matters in India.

When is a cough more than just a cough?

A cough after a cold can hang around, but in India a cough lasting two weeks or longer is an important reason to get checked for tuberculosis (TB). This is a screening signal, not a diagnosis: allergies, asthma and other conditions can also cause a long cough. Do not wait two weeks if you have alarming symptoms. [1,2]

What other signs should you notice?

TB affecting the lungs may cause fever, night sweats, weight loss, poor appetite, tiredness, chest discomfort or blood in sputum. Some people have only a few symptoms. A close contact with someone diagnosed with TB raises the importance of being assessed. [2,3]

What happens at a TB check?

A healthcare professional will ask about symptoms and exposure, and may recommend a sputum test, a rapid molecular test and a chest X-ray. The exact tests depend on your situation. A normal-looking day or an occasional dry cough does not rule out TB. [1,3]

Can TB be treated?

Yes. TB is treatable with the right combination of medicines taken for the prescribed duration. Do not self-medicate with antibiotics or stop TB treatment when you begin to feel better. In India, public-sector TB testing and treatment services are available through the National TB Elimination Programme. [1,3]

What should you do today?

If you have been coughing for two weeks or more, contact a doctor or nearby public health facility and ask whether TB testing is needed. Seek urgent care for coughing up significant blood, severe breathlessness or chest pain. While being assessed, cover your cough and improve ventilation around others.
