Question

Choose the correct order of disease control and removal.
• [A.] Disease elimination
• [B.] Disease eradication
• [C.] Disease control
• [D.] Disease screening on time Choose the correct answer from the options given below:

• A. C, B, A, D
• B. D, C, A, B
• C. D, B, A, C
• D. D, A, C, B

Hint:

Public health progression usually follows: Screening $\rightarrow$ Control $\rightarrow$ Elimination $\rightarrow$ Eradication.

Answer 1

The Correct Option is B

Concept: Disease prevention and removal follow a progressive sequence in public health. The stages generally proceed as:
• Disease screening and early detection
• Disease control
• Disease elimination
• Disease eradication
• Disease control: Reduction of disease occurrence to an acceptable level.
• Disease elimination: Reduction of disease incidence to zero in a defined geographical area.
• Disease eradication: Permanent worldwide reduction of disease incidence to zero.

Step 1: Identify the first stage.
Disease screening is performed first for early identification and prevention of spread. Thus, the first stage is: \[ D \; (\text{Disease screening on time}) \]

Step 2: Identify the second stage.
After detection, public health measures are used to control the disease. Thus, the second stage is: \[ C \; (\text{Disease control}) \]

Step 3: Identify the third stage.
Further efforts may eliminate the disease from a particular region. Thus, the third stage is: \[ A \; (\text{Disease elimination}) \]

Step 4: Identify the final stage.
The final goal is complete worldwide eradication of the disease. Thus, the final stage is: \[ B \; (\text{Disease eradication}) \]

Step 5: Determine the correct sequence.
Therefore, the correct order is: \[ D \rightarrow C \rightarrow A \rightarrow B \] Hence, the correct answer is: \[ \boxed{(B)\ D, C, A, B} \]
