  1. The Role of Public Health in the Prevention of Infectious Diseases.

  2. Public health measures typically involves eliminating the pathogen from its reservoir or from it route of transmission

  3. Safe Water • US water used for washing drinking, and preparing food is purified before it goes into homes to kill pathogens • Purified through settling, filtration, and chlorination

  4. Sewage Treatment and Disposal Sewage includes wash water, water from toilets, and storm run-off These fluids carry pathogens for diseases such as hepatitis US government mandates That sewage be treated To eliminate pathogens

  5. Food Safety • US has many standards, inspection plans and regulations dealing with food preparation, handling, and distribution

  6. Meat-packing facilities are inspected to detect diseased animals and ensure standards for meat cutting and refrigeration are observed Restaurants and supermarkets are inspected Milk is pasturized, dated for sale, and is analyzed for contamination

  7. , Animal Control Program Animals carry many diseases that affect humans Domestic herds are inspected for tuberculosis and brucellosis Owners of pets must show proof of rabies vaccination. Rabid animals must be destroyed

  8. Animal Control Programs • Bubonic plague is spread by rats so rat control in urban areas is a public health effort

  9. Animal Control Program Insects carry many diseases such as malaria Need to eliminate insect breeding areas by Draining areas where stagnant water collects Using pesticides

  10. Vaccination Programs • Vaccination programs mandate that children be vaccinated prior to starting school

  11. If a certain proportion of a population (treshold proportion) is immune to a disease, the pathogen that causes the disease will be unable to reproduce itself at a high enough level to maintain itself in the population This is called herd immunity and the pathogen could be eliminated from the population

  12. Public Health Organizations Enforce regulations Provide public health services Monitor and report incidence of Disases to state and federal agencies

  13. National Institute of Health (NIH) Is an agency of the US Department of Health and Human Services (DHHS) Supports health-related research aimed at preventing, treating, and controlling infectious diseases

  14. Center of Disease Control and Prevention (CDC) • In Atlanta, Georgia • Investigates disease outbreaks, • publishes reports, sponsors • education programs/ research, and reference labs

  15. Food and Drug Administration(FDA) Monitors safety of food, medicines and other products

  16. World Health Organization (WHO) • Provides international • surveillance and control of disease • Coordinates multinational vaccination campaigns

  17. The End
