Why Do Germs Cause Disease?

Pages 2
Louis Pasteur was a chemist who wanted to prove that germs cause disease. A famous veterinarian named Monsieur H. Rossignol thought Pasteur was crazy when he announced that you could vaccinate livestock by essentially giving them the disease that had been killing livestock all across Europe. Rossignol challenged Pasteur to do a public test of his theory. Pasteur had a attended a medical conference two years before and listened angrily as the doctors talked about a vague “miasm” that was killing mothers during childbirth. He explained to these doctors that there was no such “miasm” and the reason the mothers were dying was because the doctors and staff had germs on their hands from taking care of a sick woman, and then a healthy woman, and …show more content…
He was furious, and took it out on his assistant, Emile Roux, saying that he had prepared the vaccine wrong. Pasteur was going to make Roux go and face the public humiliation alone, but later that day, Pasteur received word that the sheep were recovering, so he decided he would attend the meeting. When Pasteur and his assistant arrived at the train station the next morning, they were met with loud cheers, telling them that their vaccine had been successful. By 2:00 that day, 23 of the unvaccinated sheep were dead, by 3:00 the 24th sheep died, and by 4:00 the 25th sheep died; all of the vaccinated sheep were healthy and well. Pasteur’s anthrax vaccine was the first effective protection in human history against infectious diseases. It also provided proof of his theory that germs cause diseases. Pasteur’s creation of the anthrax vaccine opened the door to fighting all sorts of infectious diseases including smallpox, tuberculosis, cholera, etc.
Because Pasteur questioned why women were dying during childbirth, decided it was due to germs on the doctor’s hands, and figured out a way to create vaccinations, it is now possible to be vaccinated against infectious diseases, saving millions of lives every

...Why is good hygiene important? Good hygiene stops the spread of germs and parasites. Germs are very small microorganisms which cannot be seen with the naked eye, this means you need to use some form of magnification to see them. There are two main types of germs; viruses and bacteria, and when they enter the human body they can sometimes cause diseases and make people sick. Parasites are animals or plants which must live on or in another plant or animal to survive. Examples of germs and parasites which can cause health problems include: * Salmonella (food poisoning) * Shigelia (dysentery) * Neisseria (gonorrhoea) * Chlamydia (trachoma or sore eyes) * Tetanus (lockjaw) * Head lice * Hookworm, ringworm and threadworm * Tinea * Scabies * Hepatitis (liver disease), gastroenteritis (diarrhoea and vomiting) and meningitis (brain disease) can all be caused by germs. Diseases enter a person's body by: * mouth (drinking or eating contaminated water or food) * nose * broken skin * eyes * genitals (sex organs) Some diseases can be treated by medicines at home; however others may require hospital treatment. How are germs and parasites spread? Many of the diseases above occur because of poor environmental health standards which make it easier for germs to enter a person's body. Germs can be spread by: * not washing ones hands regularly, mainly after going to the toilet. When hands are put on the face, in the mouth or on...

Model for Health and Wellness

...Anatomical, and Germ Diseases HW215-07 Models for Health and Wellness The history behind the theories. The world is made up of hypothesis and theories for why we acquire what diseases, and who was responsible for finding the answers. It is relative to say that history has taught us a lot about who, what, when, where, why and how of health and wellness. Some common concepts and theories of disease are humoral, anatomical, and germ. The humoral concept is one that describes how four elements are noticeable in disease deterioration, while the anatomical theory describes how our insides show us what disease is what, now the germ theory basically brings about the fact that bacteria is one of the leading causes for disease. All three of these theories are different in style as well as theory, but similar in many ways as well. They all come together with one common purpose, to find the disease and rid the human body of it. Now, let us get into more detail about the humoral theory a bit. What is so humorous about a disease? Nothing, because disease is no laughing matter, but something that is a fun fact is how the humoral disease came about. The humoral disease started out about the four elements: Earth, Air , Fire, and Water. What I feel is a bit comical is who brought together the humoral theories, Greeks during the Renaissance era. They felt that if one of the four elements in a persons body was out of balance, then whatever physically happened was the cause and not something...

Growing up learning about the precedence of keeping clean and remaining germ free to prevent diseases, I was intrigued, when reading through the book list descriptions, that this was a book based solely upon the usefulness and signification of diseases and how they are really living organisms partner in this world. The odd and unique title caught my attention and after I read more into Riddled with Life I was set on learning just how diseases could possibly have a positive impact on life itself. I figured this book was enriched with so many interesting facts that I could learn from and hopefully benefit from and after reading this book I found out that I had made the right decision! This book had me hooked beginning to end with interesting facts and concepts I had never even fathomed being true. Synopsis of Riddled with Life Marlene Zuk does a great job in this book describing not only how parasites are not a bad thing to live amongst and we should not be focused on the unreasonable act of destroying them but also just how much they benefit organisms human beings and flies alike. All living things benefit from parasites, they are part of what makes us who we are. However, diseases and germs are not necessarily short-term beneficial for one personally due to chronic diseases and illnesses, but the picture Zuk is aiming to create here is rather long-term benefiting the evolutionary process of life the way...

Pros And Cons Of Vaccines

...I. There are numerous amounts of diseases all over the world. In the present time, these diseases are cured or contained by vaccines. A couple centuries ago, doctor Edward Jenner developed the first vaccine in 1796. He discovered this vaccine by observing his ambiance. Jenner realized that milkmaids (tend to cattle) frequently contracted cowpox, but after they convalesced they were immune to the deadlier disease smallpox. So Jenner said, “Why not infect people with cowpox to confer immunity to the more dangerous disease.” With his research, he got the pus from a milkmaid who had cowpox and put it on a small healthy eight-year-old boys cut. Eventually, the boy was infected with cowpox, how Jenner predicted. When he was done recovering, Jenner took the riskiest step there is. Jenner deliberately injected the smallpox disease into the kid. This was a dangerous step because smallpox resulted in thousands of deaths every year or left the person disfigured. Thankfully, the boy...

Clean Hands

...hands play a major role in disease prevention and health maintenance. Researchers in London estimated that if everyone religiously practices washing their hands, one million of deaths can be prevented every year (CDC, 2013). Washing our hands appropriately before handling food helps to prevent food borne disease outbreaks and illnesses. History states that hand washing for the first time was introduced by Hungarian obstetrician Ignaz P. Semmelweiss in 1847. He demonstrated that hand washing tremendously decreased the infection number in newborns and he tried to introduce this practice to his colleagues, but they got so “offended that they committed him to an insane asylum” (B4 Brands, 2014, p.1). Fortunately, these days, health care representatives can freely increase people’s awareness and encourage individuals to promote healthy behaviors for all ages. Therefore, everyone is entitled to promote their health by practicing proper hand hygiene. According to statistics, 80% of communicable diseases are spread by touching food, and then the mouth, eyes or nose since contaminated hands spread foodborne illnesses: Salmonella, E-Coli, Staph and diarrheal infection (B4 Brands, 2014). The Virginia Department of Health, 2011 states that touching the face with contaminated hands spreads diseases like pneumonia, flu and the cold. It is extremely devastating that approximately 922,000 children died in 2015 of pneumonia and that pneumonia is the leading cause of death in children (WHO...

Jared Diamond's Paper

...world’s first farming societies emerged, leading to bigger settlements— meaning that people did not need to travel to find food. Instead, they began to live in settled communities, and grew crops and/or raised animals on nearby land. They built stronger, more permanent homes and surrounded their settlements with walls to protect themselves; one of the largest settlements in the Middle East was called Catal Huyuk which became wealthy (because of a glassy rock made from volcanos) from its farming and trading which meant the needs for markets, the need for protection and the concentration of political power. Meanwhile, humans living among farm animals developed immunity to the diseases they carried. By the time they encountered other societies, their military power, metal tools and, above all, their deadly germs gave them the decisive advantage. But Diamond is not really talking about axes; mostly he is making a rather subtle argument about the climatic advantages that (in his view) mid-latitude regions have over tropical regions. The world's largest continuous zone of "temperate" climates lies in a belt stretching across Eurasia from southern Europe in the west to China in the east. “Rather persistently neglecting the fact that much of this zone is inhospitable desert and high mountains, Diamond describes this east-west-trending mid-latitude zone of Eurasia as the world region that possessed the very best environment for the invention and development of agriculture and, consequently...

... Public health seeks to prevent disease, prolong life, and promote health through organized efforts of society, organizations, and community. The goal of public health is to create a safer and healthier society through prevention of possible health issues to society, while also helping to respond to health challenges that are negatively impacting the public. One of the greatest public health challenges of the current century is HIV/AIDS, which kills millions of people worldwide each year. In developed nations, there has been a reduced death rate from the disease due to increased access to antiretroviral therapy which has been very successful in prolonging the lives of those infected with HIV. In developing nations, there is less access to this treatment because of the lack of technology the nations possess, and due to the high costs associated with the treatment. There are different theories of public health and disease causation that changed from the 19th to 20th to now 21st century, which influenced and can explain certain policies that were made for handling HIV/AIDS. Policymaking for this deadly virus also came with the stigmatization of certain groups of people, and these stereotypes about people with HIV/AIDS even hampered policymaking to an extent. “The Age of AIDS” is a PBS Frontline documentary that looks into the disease and the public health response to it, showing how all of this really worked. There are many theories of disease causation that influenced public...

...Primary Prevention: Handwashing Education September 17, 2015 Primary Prevention: Handwashing Education Preventing a health problem before it occurs is a major goal of healthcare today. Health promotion, specifically primary prevention, is used to accomplish prevention of health problems, such as infections, before they occur (Institute for Work and Health, n.d.). “This is done by preventing exposures to hazards that cause disease or injury, altering unhealthy or unsafe behaviors that can lead to disease or injury, and increasing resistance to disease or injury should exposure occur” (Institute for Work and Health, n.d., para. 1). Providing communities with health education is the best way to satisfy primary prevention, and thus prevent an illness or disease from occurring. In order to provide appropriate education, the nurse must first assess a community of interest, and determine what health issues require the most attention. The nurse can then create a teaching plan to assist the community in preventing the identified health risk. This writer assessed the Harry Hoag Elementary School third grade class community in Fort Plain, NY. Based on the community assessment findings, handwashing education was determined to be the topic of focus for the Harry Hoag Elementary School third grade class. The community assessment, the epidemiologic reason for this topic, the teaching plan, and evaluation of the experience require a closer look. * Fort Plain is a small...

Health and Social Care

...Cause and spread of infection 1.1. Identify the differences between bacteria, viruses, fungi and parasites All 4 are different types of pathogens Bacteria is a single celled organism that multiply by themselves. They lives within and on most living and nonliving things. The majority of bacteria’s are harmless and beneficial to the human body but some can cause infectious diseases. A bacterium usually affects one part of the body and doesn’t spread across or through the body. Bacterial infections are normally treated with a cause of antibiotics. Viruses: are made up of genes and proteins that spread throughout the body by invading the body’s own cells so they can reproduce and multiply in the body. They use the body’s cells as a host because they are unable to multiply on their own. They are normally spread directly from human to human. Viruses can be very tough and there are not many effective medicines available for viral diseases. There are currently 21 families of viruses known to cause disease in humans. Fungi: like to grow in warm, moist places. Some fungi can be beneficial to us such as penicillin, but certain types of fungi can be harmful to our health. Like bacteria and viruses, some fungi can act as pathogens. Human fungal diseases can occur due to infection or fungal toxins. Symptoms for fungal diseases can be as common as itching, coughing, fever, wheezing, but they can also be as serious as meningitis or even death Parasites are organisms that use other...

He is a recipient of a MacArthur Foundation Fellowship and was awarded a 1999 National Medal of Science. He is also the author of The Third Chimpanzee. SUMMARY The book asks and attempts to answer the question, once humankind spread throughout the world, why did different populations in different locations have such different histories? The modern world has been shaped by conquest, epidemics, and genocide, the ingredients of which arose first in Eurasia. The book’s premise is that those ingredients required the development of agriculture. Agriculture also arose first in Eurasia, not because Eurasians were superior in any way to people of other continents, but because of a unique combination of naturally occurring advantages, including more and more suitable wild crops and animals to domesticate, a larger land mass with fewer barriers to the spread of people, crops, and technology, and an east-west axis which meant that climate was similar across the region. The book is well written and contains not only information about the history of cultures around the world, but excellent descriptions of the scientific methodologies used to study them, from how archeologists study the origin of agriculture to how writing evolved to how linguistics can trace the movements of peoples across huge geographic...

Hand Washing

...Robert Steinlage Persuasive Essay 12/02/2014 The most important thing you will ever do! Not washing your hands properly can cause you, or someone else to get very sick, or even die. How would you feel if someone you know or love died because of someone else not taking the time to wash their hands properly? Most people are unaware of the importance of washing their hands. Many infectious diseases are spread through direct or indirect contact. During my studies as an Emergency Medical Technician I learned the true importance of always washing your hands properly. Keeping your hands clean can prevent the chance of spreading diseases. According to a study conducted by the American Society of Microbiology, most people do not wash their hands as often as they say they do. This study found that 97 percent of females and 92 percent of males say that they wash their hand regularly. However, only 75 percent of females and 58 percent of males are actually washing their hands as much as they should. Just because you can’t see germs, it does not mean they are not there. Bacteria and viruses are microscopic organisms that can be transmitted via your hands. Germs can be passed through direct or indirect contact. Direct contact is inhaling someone else’s illness through their coughs and sneezes. Indirect contact occurs when you touch a germy surface like a door handle and then touch your nose, eyes, mouth, or someone else’s hands. Viruses can live on hard surfaces for days, to...
