respond obediently to infectious diseases by succumbing to their every need. This creates a situation where our genes as well as the environment around us influence our body 's own immune system (Genetic Control of Immune Response and Susceptibility to Infectious Diseases, 2013). The genetic variation within a number of many individuals causes natural selection to occur. With this natural selection we are susceptible to the chance of risk that can ultimately cause our immune systems to alter antagonist
During the 20th century, the infectious disease death rate decreased from 800/1000 deaths to less than 100/1000 deaths. This is mainly due to the introduction of immunisation. Vaccination has clearly prevented millions of deaths over the last century; nevertheless, the anti-vaccination movement has grown significantly in recent years. Some of the reasons why people join this movement include the belief that vaccines don’t actually work, the belief that vaccines are unnatural and therefore unhealthy
The name of the disease: Wildfire What is it? Wildfire is the common cause for a condition called Red King, which is a highly contagious viral disease caused by the king virus (KV). Most people associate wildfire with summer, for the chances of accumulating the disease is higher during summer than any other season. However, wildfire can occur at any time of the year. Children and adults can be immunised against wildfire. Is it possible to come up with an antigen for this disease? Indeed, being as
For thousands of years, infectious diseases have had a strong influence over human populations by challenging the immune system to continuously adapt to new virulent strains. With the advantage of reproducing more rapidly than the human immune response, microorganisms that cause even minor infections can prove to be fatal (Parham, 2015). Over time, outbreaks such as ‘The Great Plague’ have threatened to bring an end to society. Without the ability to contain these diseases geographically and provide
Describe a complex system or context of your choice What is the system you have chosen? Describe some of its qualities The immune system is a defence mechanism inbuilt in all living organisms comprised of specific biological processes and structures. Its purpose is to protect against disease using the networks of cells, tissues and organs that work cohesively for protection. In order to function correctly, the immune system must be able to detect and distinguish an expansive variety of pathogens
Chronic and Infectious Diseases Paper Chronic disease is a fight that many fight each day. Some argue that chronic disease can be prevented with good healthy obtained through a good diet and exercise. Individuals should seek out a doctor when he or she wants to obtain good health. Each person definition of good health would be different because his and her levels of protein, carbohydrates, fiber and fats will be different. This paper identify characteristics of chronic disease, Examine the relationship
Before vaccines were invented, whenever an individual contracted a disease, it would easily spread to the people who were in contact with the individual. Many became carriers of the disease, resulting in an outbreak. No one was immune from the disease, thus making the vast majority a suitable host for the pathogen. In 1796, British physician Edward Jenner created the first vaccination for smallpox by applying matters of fresh cowpox lesions on an infected eight years old’s hand (Riedel 2005). The
The nature of infectious disease remains a far-reaching catalyst of poor public health. The inflation of new diseases, re-emergence of diseases and antimicrobial resistance to drugs is the result of changes in society and the microorganisms themselves (Cohen, 2000). The employment of drugs to prevent and combat disease often leads to drug resistance, as determined in the current antibiotic crisis. New ways of combating disease will and are being set up, such as the new budding theory of cross-reacting

The Center for Disease Control and Prevention’s “Journey of your child’s vaccine” illustrates the complete process a vaccine must go through before it is licensed and released to the public. After a vaccine is created and manufactured for a specific disease under the guidelines of the Food and Drug Administration
1. Discuss the impact of stress on the immune system. Stress has a huge impact on the immune system. The immune system is interconnected. For example the immune, nervous, and endocrine system is linked through specialized communication pathways involving hormones, neurotransmitters, neuropeptides, and immune cell productions. Stress reactions can directly affect the various response systems and how they handle the neuroendocrine-products. This stress reaction directly affects the hypothalamus and
