Epidemiology forms the foundation of Community Health Nursing. Whether you are preparing for CHO Exams, AIIMS NORCET, or MPH Entrance, understanding disease prevention and study methods is crucial.
This daily mock test covers high-yield topics like the Levels of Prevention (Primordial, Primary, Secondary, Tertiary) with practical examples. We also focus on Epidemiological Study Designs (Cohort vs. Case-Control) and the concept of the Iceberg Phenomenon of Disease. Master these public health concepts with our solved MCQs.
Disease Prevention & Epidemiology
💡 Golden Points to Remember:
- Primary Prevention: Action taken before the disease onset (e.g., Vaccination, Helmets).
- Secondary Prevention: Early diagnosis and treatment (e.g., Pap Smear, BP Screening).
- Iceberg Phenomenon: Floating tip = Diagnosed cases; Submerged part = Undiagnosed/Carrier cases.
- Cohort Study: Prospective study (Cause to Effect).
- Case-Control Study: Retrospective study (Effect to Cause).

Frequently Asked Questions (Epidemiology)
Q1: What does the "Floating Tip" represent in the Iceberg Phenomenon?
Ans: The Floating Tip represents the clinical cases (diagnosed and visible cases) in the community. The vast submerged portion represents hidden, undiagnosed, or carrier cases.
Q2: Vaccination comes under which level of prevention?
Ans: Vaccination is a classic example of Primary Prevention (Specific Protection). It prevents the disease from occurring in the first place.
Q3: What is the main difference between Cohort and Case-Control studies?
Ans: Cohort Study moves forward from Cause to Effect (Prospective). Case-Control Study looks backward from Effect (Disease) to Cause (Risk factors) (Retrospective).
