Question

Which of the following is/are used as operation indicator in antileprosy activity?

• A. Incidence
• B. Incidence and prevalence
• C. Relapse rate and case detection ratio
• D. Incidence and case detection ratio

Hint:

Operation indicators track programme performance, not just disease burden.

Answer 1

The Correct Option is D

The National Leprosy Eradication Programme is judged both by how much disease is present and by how well the programme is finding and treating it. This question asks about the second kind, the operation indicators.

1. Incidence alone: Useful, but by itself it is only one piece of the picture and not the full operational measure used in the programme.
2. Incidence and prevalence: Prevalence describes disease burden at a point in time and is really an epidemiological indicator, not an operational one, so this pairing is not correct.
3. Relapse rate and case detection ratio: Relapse rate matters for treatment outcome monitoring, but it is not grouped with case detection ratio as the standard operation indicator pair.
4. Incidence and case detection ratio: These two together track how actively new cases are being picked up in the field, which is exactly what an operation indicator is meant to show.

So the programme uses incidence together with the case detection ratio to judge its own working, separate from prevalence, which shows disease load in the population.

Let's summarize:

• Prevalence describes disease burden, it is epidemiological.
• Incidence and case detection ratio describe programme performance, they are operational.

The correct answer is incidence and case detection ratio.
