  3. 3. DEFINING PUBLIC HEALTH: “The science and art of preventing disease, prolonging life and promoting physical health and efficiency through organized community efforts for the sanitation of the environment, the control of community infections, the education of the individual in principles of personal hygiene, the organization of medical and nursing services for the early diagnosis and preventive treatment of diseases and the development of social machinery which will ensure every individual in the community, a standard of living adequate for maintenance of health” :by Winslow [REF.:TEXT BOOK OF PUBLIC HEATH AND COMMUNITY MEDICINE:AFMC:PG 7]
  4. 4. In studying history, we are able to understand how our predicament is similar to someone else's who came prior to us. We might also be able to examine what they did and assess if this is a path that we want to take or something we wish to avoid. Studying history connects us to something larger than merely subjective consciousness. [REF:K. PARK’S TEXTBOOK OF PREVENTIVE AND SOCIAL MEDICINE.]
  5. 5. From time immemorial man has been interested in trying to control disease. The medicine man, the priest, the herbalist and the magician, all undertook in various ways to cure man's disease and/or to bring relief to the sick.

  21. 21. The Middle Ages, also known as "The Dark Ages”. Health problems were considered to have spiritual causes and solutions. Bloodletting and alchemy were common practices. Most importantly, the failure was to consider the role of the environment in health that led to epidemics and thus resulting in inability to control them.
  22. 22.  Black Plague or Black Death or bubonic plague.  It reappeared in Europe in 1348 after nearly a 1000 year absence. Up to 2/3rds of the succumbed in the first two years of the pandemic.  The pandemic was approached by scientists and by 1350 A.D.  An interesting historical footnote is that some scholars contend that corpses were used for “biological warfare.”
  23. 23.  This Era highlighted the value of a healthy and productive population, leading to advances in occupational health.  A milestone in the history of public health is the Great Sanitary awakening which took place in England & gradually spread to other countries.  Term Public Health came in to general use around 1840’s. It arose from need to protect the public from the spread of communicable diseases In 1848 (Cholera in London).  A comprehensive piece of legislation was brought into force in England, the Public Health Act of 1875 , for the control of man’s physical environment.  Preventive medicine really dates back to the 18th century. It developed as a branch of medicine distinct from Public Health. Preventive Medicine got a firm foundation after the discovery of causative agents of disease and establishment of the Germ Theory of disease.
  24. 24. PREVENTIVE MEDICINE: “The science and art of preventing disease, prolonging life, promoting physical and mental health and efficiency..” Definition: (By Leavell and Clark) • James Lind conclusively showed in 1748 that scurvy can be prevented by the use of fresh citrus fruits and vegetables. • Edward Jenner discovered small pox vaccine. • Thus the concept of ‘Preventive Medicine’ came. • And the scope of Preventive Medicine was broadened from the general measures of health promotion (hygiene) to specific measures of disease prevention (immunization).
  25. 25. COMMUNITY MEDICINE:  With the emergence of Non-communicable diseases and due to their multifactorial etiology, the concept of “MULTIFACTORIAL DISEASE CAUSATION” came into vogue.  So, measures like early diagnosis, identification of risk factors, limiting the development of disability and rehabilitation of handicapped persons were included into the subject.  Thus the scope was broadened from –  HYGIENE  PUBLIC HEALTH PREVENTIVE AND SOCIAL MEDICINE  COMMUNITY MEDICINE
