The Correct Option is B
Solution and Explanation
Step 1: Understanding the Question.
The question asks which level of prevention screening belongs to, in the context of school health services.
Step 2: Key Concept.
Prevention is grouped into three levels. Primary prevention acts before disease even begins, using tools like immunization and health education. Secondary prevention finds disease early, often before symptoms appear, and treats it promptly to stop it from getting worse. Tertiary prevention limits disability and helps rehabilitation once disease is already established.
Step 3: Detailed Explanation.
Screening tests, such as vision or hearing checks, growth monitoring, or dental checks done routinely in schools, are designed to catch disease or a health problem at an early, often symptomless, stage. Once picked up, the child is referred for prompt treatment before the condition worsens. This early detection and prompt treatment approach is the defining feature of secondary prevention.
Screening is not primary prevention, because the child may already have the early stage of disease, it is not being stopped from starting. It is also not tertiary prevention, since tertiary prevention deals with limiting damage after disease is already advanced, not with early detection.
Step 4: Final Answer.
Screening in school health services is an example of secondary prevention.
