Under NTEP, a patient who was previously treated for TB (treatment after failure, relapse, or default) is classified as:
- A New case
- B Retreatment case ✓
- C Chronic case
- D Multi-drug resistant case by definition
Correct answer: B. Retreatment case
Explanation
Retreatment cases under NTEP include relapse (cured or treatment completed but TB returns), treatment after failure (positive bacteriology at 5 months or later), and treatment after default (lost to follow-up for ≥2 consecutive months). All retreatment cases should have drug susceptibility testing performed before starting treatment. They are not automatically classified as MDR-TB without DST confirmation.
