History of Public Health

Public health studies disease and prevention at the scale of populations. Its history includes quarantine, water, housing, waste, food, vaccination, statistics, workplace danger, sanitation, epidemic reporting, and state responsibility.

The history of public health is a history of collective intervention: deciding when illness becomes a public problem, who has authority to act, and how prevention can protect some people while burdening others.

Prevention

Public health made prevention a political problem

Public health depends on things that exceed bedside medicine: clean water, waste removal, housing regulation, vaccination programs, records, inspectors, laboratories, and laws. These systems save lives, but they also require power over shared environments and private behavior.

John Snow belongs to the public-health canon because cholera investigation made disease mapping, water systems, and urban infrastructure central to medical argument.
