Difference Between Communicable And Infectious Disease

Infectious diseases are the invasion of host organisms, (microbes) which can be invisible to the eyes. The microbes are also known as pathogens. A microbe infects an organism (which is known as the host of the microbe). In a human host, the microorganism causes a disease by either disrupting an important body process or by stimulating the immune system to mount a defensive reaction. The pathogen, interferes with the normal functioning of the host and can lead to chronic wounds, gangrene, loss of an infected limb, and even death. The host's response to infection is inflammation. An interaction between parasite and host, whereby the relationship is beneficial for the former but detrimental to the latter, is characterized as parasitism.

A viruses is a non-living infection agent and can be found anywhere. it has no cell organelles. They are eliminated by the immune system. Viruses are the smallest in size of all the microbes. they may attack almost any living organism. Viruses will invade a cell in the body and uses part of the cell to multiple causing new viruses to produce. Bacteria are much larger than viruses. they live everywhere. many bacteria will not cause an infection. Bacteria multiple itself by division. Viruses and bacteria both are microscopic, contain proteins, and cause disease.

•The influenza infection is extremely infectious: When a contaminated individual coughs, wheezes or talks, respiratory droplets are produced and transmitted into the air, and can then can be breathed in by someone close-by.

Infection control refers to action devoted to policies and procedures that reduce the risk of spreading infections, reduce the occurrence of diseases caused by bacteria and viruses, parasite. The infectious diseases are normally spread by human to human, human to animal contact or by ingestion of food, droplet in the air, and contact with a surface that is the vehicle of the infective agent. H1N1, commonly known as the swine flu, a viral infection, was a cause of 2009 world-wide pandemic. The virus was first found in pigs, but a similar virus also found in humans. The virus spreads in a same manner as any other seasonal flu, mainly by droplets (small particles in the air) when an infected person coughs, sneezes or even talks, but also by touching

The novel Fever 1793 , written by Laurie Anderson, is a narrative which describes the yellow fever epidemic in the late 1700’s. This epidemic caused the deaths of 5,000 or more people in a town of 50,000 in only 3 months. A young girl named Mattie from the town of Philadelphia has to deal with the deathly illness spreading around the world. The novel begins with the death of Mattie’s childhood friend, Polly. The citizens continued their daily lives shrugging off the death as a fluke and tried to ignore the fact that something was very wrong. As more people in Philadelphia became ill, including Mattie’s mother later on in the book, she was ushered away with her grandpa to go to a safer place. Her and her grandfather are mistaken for fever

The Black Death was an epidemic since the population experienced “a widespread occurrence of an infectious disease in a community at a particular time.” The Black Death was caused by the bacterial strain Yersinia pestis, which is highly lethal. Yersinia pestis lives in the digestive system of fleas, and secondary carriers to the disease are rodents, as well as other common house and barn animals. The Black Plague was zoonotic and spread

In today’s society, specific illnesses are found in certain areas because of a lack of sanitation or limited access to medicine and vaccinations. At this point, sanitation was relatively poor everywhere, which lead to its high infection rate. Other factors such as the Arab expansion, the Crusades and the discovery of the West Indies all contributed to the spread of the disease. Humans, by nature, are curious creatures, which is one of the many reasons why smallpox escalated to multiple different areas around the world. A great example of this is the introduction of smallpox by the Spanish and Portuguese explorers. Completely unknown to the “New World,” this illness killed the majority of the local population and was one of the main reasons why the Aztec and Inca empires fell. The early settlers introduced the disease to the native population, which then led to a decline. This disease had the power to decimate entire groups of people and organizations to collapse. The effects of smallpox were devastating and noticeable and led to the fist examples of biological warfare during the Fresh-Indian War. The commander of the British forces suggested using smallpox deliberately to diminish the opposing

Plague has been responsible for some of the worst catastrophes in the story of humankind, and than once changed the course of history. (Dobson 8) There was a terrible plague that went through Europe and killed millions of people. There are many different ways to obtain the plague. Bacteria named Yersinia

Infectious diseases has most likely had the most effect on the world after the start of contact by Columbus and his men. Positively illness was the best weapon that Europeans conveyed to America. The staggering impact of sickness on Native people groups was for the most part because of the organic detachment and the restricted interruption of irresistible ailments in America before A.D. 1492. The weapon of ailment was not very much perceived by Europeans, nor purposefully utilized as a part of the early pioneer contacts. In later times, particularly the nineteenth century, illness was here and there permitted to do its harm or was intentionally brought into populaces. Then again, African, and European populaces were likewise significantly influenced

Smallpox is a contagious disease caused by the variola virus. The variola virus is the causative agent of smallpox. It can infect humans due to its ability to bypass the human’s immune responses and complement activation. Smallpox gets its name from pus-filled blisters that form during the illness. It was one of the world’s most devastating diseases known to humanity. Smallpox was responsible for an estimated 300-500 million deaths during the 20th century.

This is a research and informational paper that should give the reader a clear understanding regarding the evolution of vaccinations. There are many different cultures and influences that play a role in how vaccinations are perceived today. Some of these viewpoints are backed by research and scientific proof while others are just opinions. These are going to be touched on within this paper as well in order to give a broad picture of where vaccinations began, how they have developed through the years and the impact this has had on

The Black Plague begined in the 1348-50s, through this disease it never really vanished that quickly. The disease is caused by bacterial strain called Yersinia pestis. This bacteria is found on animals throughout the world and is usually transmitted to humans through fleas. There is 3 plagues Bubonic Plague, Septicmetic Plague, and Pneumonic Plage. The Bubonic Plague is the most common form, referring to painful swollen lymph nodes—that appears around the groin, armpit, or the neck. Septicmetic Plague is the bacteria that enters the bloodstream directly, multiply there and it’s known as septicmetic plague. Pheumonic Plague is when the bacteria spread to the lungs, it has been known for having pheumonic plague. The song called “Ring around

Poe wrote "the black death" at least two hundred years before the Ebola out break happened. So i do not think that he was talking about Ebola when he wrote it. Another thing would be the symptoms and expectancy of living.

Illness at a Metaphor by Susan Sontag discusses how metaphors complicate diseases or syndromes of multiple or unknown causes. Sontag says that the most truthful way to describe illnesses is without any influence of metaphors, to keep it as pure and scientific as possible (Sontag 3). However, metaphors are a part of everyday life and it is nearly impossible to escape the use of metaphors to describe illnesses.

DNA has a massive job of keeping you alive. In essence, a microscopic strand of genes support your entire body and life. There are many smaller jobs protein has to accomplish that combine to accomplish the main job of supporting life. To start, DNA codes for proteins and every protein provide an essential biological function. Also, cells make up tissues, organs, and body systems. Body systems interact with each other to maintain homeostasis.
