🎯 Exam Connection

Frequency: This topic appeared in every single one of the last 5 AQA sittings — sometimes twice in the same paper (appearing as both an explain question AND an essay). Public health is the single most examined topic in the entire Medicine Through Time unit. If you revise only one topic from this unit, make it this one.

Typical questions you will face:

• "Describe two features of public health in 19th-century Britain" (4 marks, AO1) — You need two distinct features, each with specific supporting evidence. "Public health was poor" is Level 1. "Cholera epidemics were frequent, with the 1831 outbreak killing 32,000 people and the 1848–49 epidemic killing 62,000, because most people relied on cesspools and contaminated water pumps for their water supply" is Level 2 and scores full marks on one feature.
• "Explain why there were improvements in public health in the 19th century" (8 marks, AO1+AO2) — You need at least two developed causes with evidence and causal language. Aim for three causes showing how they connect: individual (Snow), pressure event (Great Stink), and government action (1875 Act). Level 3 requires showing HOW the factors connected — not just listing them.
• "How far do you agree that the role of individuals was the main reason for improvements in public health in the 19th century?" (12+4 SPaG marks, AO1+AO2) — Full essay requiring: argument FOR (Snow's investigation, Chadwick's report, Bazalgette's sewers), argument AGAINST/alternative (government legislation, Great Stink as pressure event, germ theory), and a clear final judgement explaining which factor was most important and why. The SPaG 4 marks reward clear sentences and accurate spelling of technical terms.
• "Describe two features of the work of Joseph Bazalgette" (4 marks, AO1) — A named individual question. Feature 1: he designed and built 1,100 miles of sewers under London between 1858 and 1875. Feature 2: his sewers used an intercepting system that carried sewage far downstream rather than pumping it into the Thames near central London, eliminating the source of contamination.

What examiners want for Level 3 on the 8-mark explain question: Developed explanation with a range of evidence. This means: name the factor → explain HOW it caused improvement → give specific evidence (date, statistic, name) → link to at least one other factor. "John Snow's 1854 investigation proved cholera was spread by contaminated water rather than miasma. By mapping 500 deaths around the Broad Street pump and persuading the local vestry to remove the pump handle, he demonstrated that cholera could be controlled by controlling water supplies. This built the scientific case for the 1875 Public Health Act, which made clean water provision compulsory across all local authorities."

What examiners want for Level 4 on the 12-mark essay: A complex, sustained argument that shows how factors interconnect and reaches a supported judgement. "Although Snow's individual investigation was crucial in proving waterborne transmission, it was arguably the Great Stink of 1858 that was more important — because Snow's discovery alone did not produce legislation. Government only acted when MPs experienced the smell of the Thames in their own building. This shows that individuals provide the evidence, but pressure events create the political will to act on that evidence. The two factors were therefore interdependent."
