Criteria for a disease fit for screening including-
**Core Concept**
Screening for a disease involves a public health strategy aimed at identifying cases of the disease in a population before the onset of symptoms, allowing for early detection and treatment. This requires the disease to meet specific criteria.
**Why the Correct Answer is Right**
The correct criteria for a disease fit for screening include high prevalence, significant morbidity or mortality, a clear and acceptable screening test, a recognizable latent or early asymptomatic stage, and a potential for intervention. The disease should have a high prevalence in the population to justify the resources required for screening. Significant morbidity or mortality justifies the effort to detect the disease early. A clear and acceptable screening test is essential to ensure accurate diagnosis. The disease should have a recognizable latent or early asymptomatic stage to allow for early detection. Finally, there should be a potential for intervention to reduce morbidity and mortality.
**Why Each Wrong Option is Incorrect**
**Option A:** is not a correct criterion for screening. While cost-effectiveness is an important consideration, it is not a primary criterion for selecting a disease for screening.
**Option B:** is also not a correct criterion. While a screening test should be acceptable to the population, this is not a primary criterion.
**Option C:** is not a correct criterion either. While a disease should have some potential for intervention, this is not a primary criterion for screening.
**Clinical Pearl / High-Yield Fact**
When considering a disease for screening, it is essential to weigh the benefits of early detection against the potential harms of over-diagnosis and over-treatment.
**Correct Answer: D.**
