Effective leprosy control programme may be indicated bn all of the following except ?
**Core Concept**
Leprosy control programs aim to reduce the incidence and prevalence of leprosy through early detection, treatment, and prevention of disability. Effective leprosy control involves a combination of strategies, including mass screening, contact tracing, and multidrug therapy (MDT).
**Why the Correct Answer is Right**
The correct answer is related to the concept of "mass screening" in leprosy control programs. Mass screening is a strategy where entire populations are screened for leprosy, even if they do not show symptoms. This approach is effective in detecting cases early, reducing transmission, and preventing disability. Leprosy control programs often rely on active case finding, which involves searching for cases among high-risk populations, such as those living in areas with high leprosy prevalence.
**Why Each Wrong Option is Incorrect**
* **Option A:** Mass screening is an important component of leprosy control programs, so this option is not correct.
* **Option B:** Multidrug therapy (MDT) is a cornerstone of leprosy treatment, and its use is recommended by the World Health Organization (WHO). Therefore, this option is not correct.
* **Option C:** Contact tracing is an essential aspect of leprosy control programs, as it helps to identify and treat individuals who have been in close contact with an infected person. This option is not correct.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that leprosy control programs often focus on high-risk populations, such as those living in areas with high leprosy prevalence, and that active case finding is a key strategy in detecting cases early.
**Correct Answer: D.**
