Which term refers to population-level strategies to prevent disease?

• A. Public Health Strategies
• B. Complementary Medicine
• C. EHR
• D. Health Data Collection

Answer: (A)

Population-level disease prevention relies on actions that protect whole communities, not just individual patients. Public health strategies are the organized, evidence-based efforts to reduce disease risk across populations. This includes vaccination programs to prevent outbreaks, improving sanitation and living conditions, policies that create healthier environments, broad health education, and surveillance to monitor disease trends and guide interventions. The aim is to prevent illnesses before they occur or minimize their impact at the community level.

Complementary medicine involves non-conventional therapies used alongside standard care and is usually individualized. An electronic health record stores a patient’s medical history and is used for care at the individual level. Health data collection is the process of gathering information about health status and determinants; it supports planning and understanding health trends, but on its own it isn’t the population-wide prevention strategy.
