Suspected tuberculosis

A cough lasting several weeks (typically more than 2–3 weeks), night sweats, unexplained fever, weight loss and blood‑tinged sputum can raise suspicion. Seek medical assessment when these symptoms persist.

Common tests include chest X‑ray or CT, sputum examinations (microscopy, culture, PCR/NAAT) and immunological tests (tuberculin skin test or IGRA). The exact tests depend on clinical context and local protocols.

TB is mainly airborne via respiratory droplets. Reduce risk by avoiding prolonged close contact with infectious individuals, improving ventilation, and following respiratory hygiene. Follow public health advice if exposure is suspected.

Seek emergency care for severe shortness of breath, large amounts of bloody sputum, sudden worsening, or any other signs of acute deterioration. This information is general—don’t delay emergency services when needed.
