What are the primary goals of TB therapy?

• A. Cure the patient
• B. Prevent relapse
• C. Cure the patient, prevent relapse, prevent resistance, and reduce transmission
• D. Reduce transmission

Answer: (C)

TB therapy is aimed at more than just eliminating the current infection. The best approach combines four interconnected goals: cure the patient, prevent relapse, prevent the development of drug resistance, and reduce transmission. Curing the patient means eliminating the active bacteria so symptoms disappear and the person no longer feels ill. But stopping treatment early or not using an effective multi-drug plan can leave a small number of bacteria behind, leading to relapse even after symptoms improve. Preventing relapse requires completing the full, prescribed course and maintaining adequate adherence so the infection doesn’t come back. Preventing resistance is crucial because using multiple drugs from the start makes it much harder for the bacteria to adapt and become resistant, which would make future treatment far more difficult. Reducing transmission shortens the time a patient is infectious, protecting others in the community. A comprehensive regimen that achieves cure while ensuring adherence, using combination therapy, and minimizing infectiousness addresses all these goals simultaneously. Focusing on only one aspect—like just curing symptoms or just cutting transmission—misses the other essential pieces and can lead to relapse or drug resistance or ongoing spread.
