Presentation Transcript

Detailed slide-by-slide text content extracted from this presentation.

Slide 01

The Quiet Revolution

  • PG. 01 — INTRODUCTION
  • Between 1900 and 2000, life expectancy at birth rose from ~47 to ~77 years in the United States. Modern medicine — antibiotics, surgery, transplant — accounts for some of that. The rest came from public health: clean water, vaccines, sanitation, food safety, occupational regulation, tobacco control, road safety.
  • The CDC's "Ten Great Public Health Achievements of the 20th Century" lists vaccines, motor-vehicle safety, workplace safety, infectious disease control, declines in heart disease and stroke, food safety, healthier mothers and babies, family planning, fluoridation of drinking water, and recognition of tobacco as a health hazard.
Slide 02

Counting What Kills

  • PG. 02 — EPIDEMIOLOGY
  • Epidemiology studies the distribution and determinants of health states in populations. It begins with describing — who, where, when — and proceeds to test causes and interventions.
  • The discipline's founding moment: London, 1854. John Snow mapped cholera deaths around Broad Street, traced them to a contaminated pump, and convinced authorities to remove its handle. Outbreak ended. Snow had no germ theory; he had data.
  • Key measures
  • Incidence — new cases per population per time
  • Prevalence — total cases at a moment
  • Relative risk — exposed risk ÷ unexposed risk
  • Number needed to treat (NNT)
Slide 03

Best Buy in History

  • PG. 03 — VACCINES
  • Vaccines work by exposing the immune system to a harmless version of a pathogen — killed, attenuated, subunit, or mRNA — so memory cells are ready when the real thing arrives.
  • VaccineYearPioneer
  • Smallpox1796Edward Jenner
  • Rabies1885Louis Pasteur
  • Diphtheria toxoid1923Ramon, Glenny
  • Polio (inactivated)1955Jonas Salk
  • Polio (oral)1961Albert Sabin
  • Measles1963Maurice Hilleman
  • HPV2006Frazer, Zhou
  • COVID-19 (mRNA)2020Karikó, Weissman
  • Smallpox killed an estimated 300 million people in the 20th century alone. WHO declared it eradicated in 1980 — the only human disease ever eliminated. Polio eradication remains close but incomplete; wild poliovirus type 1 persists in Afghanistan and Pakistan.
Slide 04

Pipes, Soap, Survival

  • PG. 04 — SANITATION
  • people without safely managed sanitation (WHO 2023)
  • 829k
  • deaths/yr from unsafe water, sanitation, hygiene
  • 1854
  • London Broad Street pump removed
  • Chlorination of municipal water (Jersey City, 1908) cut typhoid death rates dramatically. Florence Nightingale's statistics from Crimea (1854–56) showed soldiers were dying more from disease than wounds — the basis of modern hospital sanitation.
Slide 05

The Epidemiological Triangle

  • PG. 05 — HOST · AGENT · ENVIRONMENT
  • Disease emerges from the interaction of an agent (pathogen), a host (susceptibility), and the environment (conditions). Public health interventions can target any vertex.
  • Vector-borne diseases add a fourth: malaria needs Anopheles mosquitos, breeding water, infectious humans, and immunologically naive hosts. Bed nets, larvicides, antimalarials, and vaccines (RTS,S, R21) attack different vertices.
Slide 06

The Most Successful Behavior Change

  • PG. 06 — TOBACCO CONTROL
  • The 1964 Surgeon General's Report on Smoking and Health concluded that cigarette smoking causes lung cancer. US adult smoking fell from 42% (1965) to 11.5% (2022). The combined toolkit — taxes, advertising bans, smoke-free laws, packaging warnings, nicotine replacement, public-information campaigns — is the textbook example of multi-pronged public-health intervention.
  • "Smoking kills. If you're killed, you've lost a very important part of your life." — Brooke Shields, anti-smoking ad, 1996.
Slide 07

How We Know What We Know

  • PG. 07 — STUDY DESIGNS
  • DesignStrengthUse
  • RCTCausal, controls confoundingDrug efficacy
  • CohortTime-direction, multiple outcomesRisk factors over decades
  • Case-controlEfficient for rare diseaseOutbreak investigation
  • Cross-sectionalPrevalence at a momentNational surveys (NHANES)
  • EcologicalPopulation-level signalsHypothesis generation
  • The Framingham Heart Study (1948–) is the most influential prospective cohort in history, defining "risk factor" as a concept and identifying smoking, hypertension, and cholesterol as cardiovascular drivers.
Slide 08

What Governments Can Do

  • PG. 08 — POLICY LEVERS
  • Regulation
  • Mandatory seat-belts, lead in paint, trans-fat bans, drinking-water standards.
  • Taxation
  • Cigarette excise, sugary-drink levies (Mexico, UK), alcohol minimum unit pricing.
  • Information
  • Front-of-pack labeling, calorie posting, tobacco warnings, anti-smoking campaigns.
  • Default change
  • Iodized salt, folic-acid fortification of flour (cuts neural-tube defects), water fluoridation.
  • Built environment
  • Bike lanes, walkable cities, lead pipe replacement.
  • Insurance
  • Universal coverage, Medicaid expansion, free vaccination programs.
Slide 09

One World

  • PG. 09 — GLOBAL HEALTH
  • The WHO (founded 1948) coordinates 194 member states. Gavi (2000) and the Global Fund (2002) finance vaccines and HIV/TB/malaria control. The Sustainable Development Goals (SDG 3) target universal health coverage by 2030. Pandemic preparedness — funding, surveillance, equitable distribution — is the defining global-health challenge of our era.
Slide 10

Zip Code, Genetic Code

  • PG. 10 — HEALTH DISPARITIES
  • Where you live predicts how long you live. In the US, life expectancy can vary by 20+ years between neighborhoods a few miles apart. Drivers include income, education, neighborhood resources, racism, and access to care.
  • The "social determinants of health" framework — championed by Sir Michael Marmot's Whitehall studies and the WHO Commission (2008) — argues that health is created where people live, learn, work, and play, far more than in clinics.
Slide 11

  • PG. 11 — WATCH
  • // Crash Course Public Health
  • An accessible 11-episode series covering public health concepts, history, and modern challenges.

  • Books: Hans Rosling's Factfulness; Paul Farmer's Pathologies of Power; Atul Gawande's The Checklist Manifesto; Michael Marmot's The Health Gap.
Slide 12

What's Strong, What's Not

  • PG. 12 — EVIDENCE
  • Strong: vaccine efficacy, smoking-cancer causation, sanitation impact, seat-belt and helmet effects, fluoridation safety, mosquito-net efficacy. Moderate: many social-determinant interventions (causal pathways are complex). Weak/contested: many wellness fads, rapid-result diet claims, mass-screening for low-prevalence conditions (overdiagnosis is real).
  • Public health works at population scale, where small per-person effects multiply into enormous total effects — and where individual experience may diverge from average outcomes. This is why "I never wear a seat belt and I'm fine" is true for the speaker and irrelevant to the policy.
  • Educational content. For personal health decisions, consult a clinician.
