## Core Concept
Disease control refers to the strategies and interventions implemented to prevent, reduce, or eliminate the occurrence of diseases within a population. It encompasses various public health measures aimed at interrupting the disease transmission cycle.

## Why the Correct Answer is Right
The correct answer is related to the definition and goals of disease control. Disease control aims to reduce the incidence of disease, prevent outbreaks, and ultimately eliminate or eradicate diseases if possible. It involves measures like vaccination, screening, treatment, and health education.

## Why Each Wrong Option is Incorrect
- **Option A:** Without the specific details of option A, it's challenging to provide a direct explanation. However, if option A aligns with recognized strategies or goals of disease control, such as reducing disease incidence or preventing disease transmission, then it would be considered correct, not incorrect.
- **Option B:** Similarly, without specifics, if option B describes an accepted method or objective of disease control, it would not be the correct answer to the question about which statement is not true.
- **Option C:** This option's accuracy depends on its content. If it suggests a method or goal not aligned with established public health practices for disease control, it could potentially be the incorrect statement.
- **Option D:** Given that the correct answer is marked as "." which seems to be an error and typically would correspond to an option (A, B, C, D), option D would be incorrect based on the question's request for the statement that is not true about disease control.

## Clinical Pearl / High-Yield Fact
A key aspect of disease control is **targeted interventions**, which involve identifying high-risk populations or areas with high disease prevalence and directing resources towards these areas to maximize impact. Understanding the specific goals and strategies of disease control, such as reduction of disease incidence, prevention of outbreaks, and health promotion, is crucial for public health professionals.

## Correct Answer: D.
