The Deadliest Disease in the World

Coronary artery disease (CAD) is the most deadly disease in the world. CAD occurs when plaque builds up in the arteries causing blood clots and restricting the heart of oxygen. CAD is the number one cause of death in the United States and the world. Medications and treatments are available but nothing can take the place of being proactive and preventing the disease. ("What Is Coronary Heart Disease?")
Coronary artery disease is caused when cholesterol containing deposits of plaque buildup inside the arteries that supply blood to your heart. As the plaque builds up, it begins to narrow your arteries, decreasing the amount of blood flow to your heart. The plaque often attracts other fibrous tissue such as calcium and blood components which further harden the artery by causing blood clots to form. Over time, the decreased blood flow will cause shortness of breath, chest pain and even heart attack. ("What Is Coronary Heart Disease?")
According to the center of disease control, heart disease is the number 1 cause of death in the United States, killing over 780,000 people every year. Specifically, coronary artery disease is responsible for killing over 380,000 people per year. ("Heart Disease: Scope and Impact") Cardiovascular disease takes more lives than all forms of cancer combined. Furthermore, someone will have a heart attack every 34 seconds in the United States, and every 60 seconds someone will die from a heart related disease. Research shows that in 2011 326,000 people had a heart attack outside of a hospital setting, of those eventually treated by emergency services only 10.6% survived. ("Heart Disease: Scope and Impact")
The system most directly affected by CAD is obviously the heart, however atherosclerosis can occur in different blood vessels throughout the body. This

Race: the World's Deadliest Social Disease

...The journal article I chose, Race: The World’s Deadliest Social Disease by Timothy McGettigan, discusses racism in our society and how this ‘socially-constructed disease’ is due to a specific type of ignorance. The article goes into details on how racism can be avoided if people were more educated on science. This argument is then supported throughout the article with specific details and information on how humans are all essentially the same and that if certain people hate others due to their genetic attributes then, technically, they hate themselves as well. Furthermore, the article explains how genetic diversity is adaptively advantageous since there is a greater chance of a species to be plagued by parasites if they are too genetically similar. The wider the variation in the gene pool, the more difficult it is for parasites and other undesirable invaders to interfere. I think this article not only relates to me but to everyone since we all live in a society with lots of diversity. Diversity is not something that we can escape and I think it’s important to know how to handle it. This article is very informative about what causes diversity to emerge among humans and how we should not be afraid of it or discriminate towards those who not look like us. At the end of the day, diversity is only beneficial to the human race. Also, I can relate to this article since I come from a different country so I have been exposed to a great amount of diversity in my life. This eye opening...

Every Day in America

...Kennedy,” Nationally, cigarettes kill well over four hundred thousand people each year.” I strongly suggest that tobacco shouldn’t be legal because it’s bad for one’s health, and it can be the most preventable cause of someone’s death. Tobacco is one of the most deadliest, yet legal drugs known to mankind. According to CDC (U.S. Centers for Disease Control and Prevention), “Smoking causes 443,000 deaths each year in the United States. 443,000. That’s more than the population of some small cities in America. Cigarettes take more lives than automobile accidents, alcohol abuse, illegal drugs, AIDS, murder, and suicide all combined. (Edward M. Kennedy). Tobacco contains nicotine which is one of the most addictive chemicals that exist. Nicotine is actually used to kill insects, and is more addictive than the illegal drug famously known as crack cocaine. But nicotine is just one of the many deadly chemicals in cigarettes. The deadly habit of smoking tobacco has actually existed for centuries. According to an article titled “Smoking” from 2010,” The dangers of tobacco were not always well known. It was smoked by early Native Americans during religious ceremonies. European explorers to the New World took tobacco plants with them, and the use of tobacco became common in Europe by about 1600. At first, most users smoked the dried leaves in pipes or cigars, or inhaled powdered tobacco, called snuff. Not everyone embraced tobacco. Some considered its use immoral...

Influenza Research Paper

...first recorded instance of the symptoms of Influenza was by Herodotus almost 2400 years ago, but the understanding of the disease was not discovered until much later. They knew what the symptoms did, but they didn’t understand it like we do now that the flu was connected to animals such as birds and pigs. In 1918 J.S. Koen, a veterinarian discovered symptoms of influenza in the pigs he treated with symptoms of the Spanish Flu that was devastating the world at the time. Independent researchers of this disease McBryde and Robert Shope, were the first scientists to study and begin to understand the disease. It was first identified in 1933 through the researcher's Wilson Smith, Christopher Andrews, and Patrick Laidrow. The first vaccine for...

The Deadliest War in the World

... The Deadliest War in the World Roy A. Richards Union Institute & University October, 2008 The Deadliest War in the World In this article, I will discuss the battle in the Democratic Republic of Congo (DRC) and the struggle that thousands of people face as they battle the government for natural resources. This article will show how this country is affected by famine, rape, and murder and what steps the government is taking to eliminate these problems. The Democratic Republic of Congo is the third largest country in Africa and is located in the Central African UN subregion. The word “Congo” means “hunter” and was named after the Bakongo ethnic group who live in the Congo River basin. Following the country’s post-independence the former Belgian Congo was changed to The Democratic Republic of Congo on August 1, 1964 to distinguish it from the Republic of Congo. In 1960 General Joseph Motubu came into power, changed his name to Motubu Sese Seko, and changed the country’s name to the Republic of Zaire. 1997 was the year rebel forces (backed by Laurent Kabila) changed the country’s name back to the Democratic Republic of the Congo, and this change cased a new rebellion between him and former allies in 1998, and so began “Africa’s World War”...

Ebola and Its Dangers

...A virus is a small infectious agent that replicates inside of living organisms. viruses can infect all types of living forms from animals humans and other cells and bacteria.There are many harmful viruses in the world however one of the most deadliest virus's known to man is the Ebola virus.The Ebola virus is one of the most difficult to contain or control. It also is one of the fastest killing viruses in the world. I personally have researched other viruses and diseases in the past for highschool,but Ebola after researching it scares me the most. The ebola virus is a very complex level four virus. Level four viruses are extremely lethal, and there is no cure for them yet, not does there seem to be a cure for them or ebola in the near future. To give you an example of just how lethal level four viruses like ebola are, AIDS is only a level three virus, and requires minimal protection when working with it. The protection required for working with the ebola virus consists of wearing three layers of gloves, and giant space suits. Only people with top government security are allowed into these airtight rooms where this all takes place. The virus is a member of the family filoviridae.Throughout media coverage, talk at work, or just rumors, you tend to think that just by being near someone with the virus that you will contact it.My daughter and niece even play around saying don't touch me or I will get Ebola. However the reality of it is that it can only be contracted through...

Persuasive Essay Against Animal Testing

...Perhaps the most infamous cases of human experimentation were revealed during World War I, concerning Nazi experiments on concentration camp prisoners. These barbaric acts often included mind-altering substances, involuntary sterilization, inducing hypothermia, and exposing subjects to diseases such as tuberculosis. Treating a non-consented patient in such a derogatory and fraudulent manner is completely against all ethicality. Animal testing, on the contrary, is done with more awareness and consciousness of the animal. In fact, 92% of all animals used in experimentation do not suffer through distress by the use anesthesia, a medicine that controls pain in a procedure or surgery. This allows researchers to perform their trials with efficacy and meet the best clinical requirements without agonizing the animal. In scientific research, there are cases where research cannot meet the usual ethical safeguards due to no universal accepted...

Clash of Cultures

...biggest reason for victory, however, was unintended. You could call it biological warfare before there was even such a thing or term. When the colonists came to the New World they brought something hidden that the Native Americans never saw coming. The Colonists main weapon was called disease. When the Europeans made their way across the Atlantic Ocean, they were armed with microbes that had never before been introduced to the new world. The Columbian Exchange is a term that has been coined describing the introduction of new animals, plants and technology ideas by the Europeans to the New World. The introduction of new disease worked the other way around in regards to the introduction of new things being taken back to Europe from the New World. Many of the new things brought forth to the new world had positive economic impact. Unfortunately, with these new additions to life in the new world came the unintentional introduction of Diseases never before seen by the Native Americans. The Native Americans were the group that was hardest hit by disease in terms of the number of deaths. According to "Gettysburg.edu" (n.d.), “Since the Indians were isolated from other cultures and peoples before the arrival of the Europeans, this weakened their defenses against the major diseases of mankind.” The deadliest...

Gun Control Argument Essay

...Of the 2,596,993 total deaths in the US in 2013, 1.3% were related to firearms. Many children have injured themselves or others with a gun. The United States has 88.8 guns per 100 people, or about 270,000,000 guns. This is the highest total per capita number in the world. 22% of Americans own one or more guns, 35% of whom are men and 12% are women. Some believe that there should be stronger gun control while others believe that it’s their right to bear arms under the second amendment of the US Constitution. To bring gun violence under control there should be stronger gun regulations to limit access and possession of guns by ordinary Americans. Stronger gun control will remove guns from the hands of people with mental...

The Influenza Virus

...one of the deadliest. People don’t really think about the flu as deadly, but thirty-six thousand people die from the flu each year in the U.S alone. There are also more than two hundred thousand people that are hospitalized because of the flu. The influenza virus is one of the most complicated and unpredictable viruses there is. The Influenza virus can be broken down into three categories. The first category is Influenza type A. Wild aquatic birds such as ducks, geese, swans, gulls, shorebirds, and terns are the natural hosts for all influenza type A viruses. Most people refer to this type of flu virus as the Avian Flu. This type of flu can further be broken down into two different subtypes based on the proteins on the surface of the virus. These subtypes are hemagglutinin (HA) and neuraminidase (NA). There are eighteen known HA types and eleven NA types. There are many different combinations of the two subtypes. All known types of type A can effect birds except two different types, H17N10 and H18N11, which have only been found in bats. Only two influenza A virus types are currently circulating among humans. These are H1N1 and H3N2. Influenza A is constantly changing and is generally responsible for large flu pandemics. “Flu pandemics occur when a new influenza (or flu) virus emerges for which people have no or little immunity and no vaccine exists” (Melone). This idea from Melone shows how deadly influenza type A can be. It is the deadliest...

Sin Taxes

...Research has shown that the use of some products, such as tobacco and alcohol, have lifelong negative effects on the human body and bystanders alike. Tobacco use has had a progressive rise in the past few decades due to marketing and the widened use in movies and other broadcasted programs seen by many people. In turn consumers assume the use of tobacco is a “cool” thing to do and find themselves soon addicted to these products. Unfortunately users disregard the statistical facts that the short and long term effects of tobacco use not only hurt the human body but those around the user. Smoking is responsible for several diseases, such as cancer, long-term (chronic) respiratory diseases, and heart disease, as well as premature death. Over 440,000 people in the USA and 100,000 in the UK die because of smoking each year. According the US CDC (Centers for Disease Control and Prevention), $92 billion...

Black Death During The Dark Ages

...There were many different theories about the origin of the Black Death during the outbreak during the Dark Ages. Some believed the disease was caused by miasma, bad water, bad smells, by sight, by poison, by Jews or simply as vengeance sent from God. Some of these combined Jews poisoning wells, God and miasma. None of them came close to understanding that the disease was bacterial in nature and was being spread by fleas infecting rats. Perhaps the closest to the truth was Girolamo Fracastoro who described the cause as a seed of contagion. The response to the disease varied and changed as time went by. Quarantine and Isolation were used to stop the spread of the disease. There were attempts at masking the bad smells believed to cause the disease...
