Which item is explicitly listed as an Old Public Health incentive?

• A. Private hospital expansion
• B. Mass Vaccination Programs
• C. Genetic screening programs
• D. Fitness app promotion

Answer: (B)

Old Public Health centers on population-wide disease prevention, using measures that stop illness before it affects people. Mass vaccination programs are a classic example because they aim to immunize large groups to prevent infectious diseases from spreading, protecting the whole community and reducing outbreaks. This reflects the era’s emphasis on government-led, preventive actions that improve population health. The other options sit more with later public health thinking: expanding private hospital capacity is about treatment access rather than preventing disease across the population; genetic screening and fitness app promotion focus more on individual risk assessment and personal behavior, aligning with newer approaches to health promotion.
