Health Sciences 20 1.1 - HISTORY OF MEDICINE Ancient Times In ancient times, the common belief was that disease and illness were caused by evil spirits and demons. Religion played an important role in health care, as sickness was seen as a punishment. ◦Religious rites were used to eliminate evil spirits and restore health. The human body was a mystery as most religions did not allow dissection of the body. Ancient Cultures and Medicine Egyptians ◦The first people to record health records – but most people could not read. Greeks ◦Hippocrates, the “Father of Medicine,” helped prove that disease is caused by natural causes. ◦The Greeks were the first to stress that a good diet and cleanliness would help prevent disease. The Romans The Romans The Romans realized that disease was connected to filth, bad water, and poor sanitation. ◦ They built sewers for waste, and aqueducts to deliver clean water. ◦ They created laws to keep streets clean and eliminate garbage. ◦ The first hospitals were also established. Chinese ◦ Held a strong belief in holistic health methods – which stress treating the entire patient – mind, body, and soul. Aqueducts Ancient Roman Aqueducts The Dark Ages (400 – 800 AD) After the fall of the Roman empire, the study of medicine stopped. Emphasis was placed on saving the soul – the study of medicine was illegal ◦Prayer and divine intervention were used to treat illness and disease Average life span was 20 to 30 years Middle Ages (800 – 1400 AD) The study of medicine was allowed again Monks found and translated the writings of Greek and Roman physicians Medical universities were created in the 9th century to train doctors how to use this knowledge Average life span was 20 to 35 years The Black Death In the 1300s, a the bubonic plague (the black death) killed approximately 50 million people The disease was carried by rats and is cured today by a simple antibiotic About 7 million have been killed by Covid The Black Plague (Start at 4:55) Renaissance (1350 – 1650 AD) This time is known as the “rebirth of science of medicine.” The major source of information was a result of accepting and allowing human dissection ◦Doctors could now view body organs and see the connection between different systems. ◦Michelangelo and Leonardo da Vinci were able to draw the body accurately. Average life span was 30 to 40 years. Da Vinci’s Drawings The 16th, 17th, and 18th Centuries Physicians were learning more and more about the human body A major development was the invention of the microscope by Anton van Leeuwenhoek ◦Even though they didn’t know it, physicians were looking at germs that cause disease. At the end of the 18th century, Edward Jenner developed a vaccine to prevent smallpox, a deadly disease. The average life span increased to 40 to 50 years. The 19th Century This was the period known as the Industrial Revolution. Major progress occurred because of the development of machines and access to books. Physicians began to associate the tiny microorganisms seen in the microscope with diseases. The average life span increased to 50 to 65 years. The 20th Century This period showed the most rapid growth in health care. Physicians were able to use new machines such as X-rays to view the body. Medicines, including antibiotics to fight infections, were developed. Surgical techniques have provided cures for what were once fatal conditions. Computers are used in every aspect of health care. The average life span is 60 to 80 years. What’s Next in Health Care? Let’s watch a video on the genome revolution then it will be your turn to do a little research. The Genome Revolution Begins With You – Ted Talks (10:52) New Tech in Healthcare In groups take 10-15 minutes to research some new technologies in health care Write down on a big sticky note and present to the class
