  17. Great Sanitary Awakening (1800s-1900s) • Growth in scientific knowledge • Humanitarian ideals • Water supply and sewage removal • Monitor community health status • Connection between povertyand disease • Even today, poverty is the single best predictor of poor health.

  18. Steps to a Healthier Society • 1840s to 1890’s -focused on the environment of infectious diseases related to “urbanization, poverty and squalor”. • 1890’s to 1930’s - personal preventive medical services and health education on: immunization, family hygiene and family planning • 1930’s and on- improving organized medical services, new meds: insulin and antibiotics, etc. • 80’s on- A recognition that the ‘environment’ is also social, economic and psychological factors affect health

  20. Broad Street Pump No pump handle, no water, no cholera

  21. Epidemiological Process • Study cases to identify the disease. • Look for possible causes. • Track the source. • -------------------------- • Make a treatment plan. • Stop the origin • Stop the spread. • Prevent further outbreaks

  22. Map of Diphtheria DeathsNew York CityMay 1, 1874 to December 31, 1875 Made under the direction of W. De F. Day, M.D., Sanitary Superintendent, NYC Health Dept.www.ihm.nlm.nih.gov

  23. Growth in Scientific Knowledge(Beforethe late 1800’s – we didn’t know anything about microbial pathogens!) • Louis Pasteur • 1862 germs caused many diseases! (rabies vaccine, Pasturization of milk…) • 1888 first public health lab • Robert Koch • 1883 identified the vibrio (water bacteria) that causes cholera, 20 years after Snow’s discovery • Discovered the tuberculosis bacterium 1822-1895 1843-1910

  24. Sanitary Reform England 1842 Edwin Chadwick’s “Survey into the Sanitary Condition of the Labouring Classes in Great Britain” Graphic descriptions of filth and disease spread in urban areas, More than half of working class children died before their fifth birthday; average age of death for common laborers was 16. • 1848 General Board of Health U.S. • 1850 Lemuel Shattuck’s “Report of the Sanitary Commission of Massachusetts” • 1869 State Board of Health 1800-1890

Sanitation Revolution – Cleaning Up! • Clean water; water treatment • Food inspection • Soaps, disinfectants, and pharmaceuticals • Personal hygiene (bathing) • Public works departments; garbage collection, landfills, and street cleaning • Public health departments and regulation • -The death rate in children drops and the average life span increases over the years from less than 40 to 74.
