DOTS in reference to tuberculosis means–

Correct option is B

Sol. DOTS stands for Directly Observed Treatment, Short-course, which is the globally recommended TB control strategy. Under this approach, a healthcare worker observes the patient while they take their medication to ensure compliance and prevent drug resistance. It is a key part of the National TB Elimination Programme (NTEP).
Explanation of each option:
· (a) Duration of tuberculosis treatment schedule – Refers to time only; DOTS is about supervision, not just duration.
· (b) Directly observed treatment, short course – Correct answer. It ensures treatment adherence and reduces drug resistance.
· (c) The spots that appear on the skin during treatment – This is not related to DOTS. TB skin manifestations are not part of the acronym.
· (d) Drugs of tuberculosis, short course – Partly true, but misses the “direct observation” element central to DOTS.
