Epidemics and pandemics have been around for centuries and have killed several thousand people. 50,097 people died in 2011 from two harmful epidemics called pneumonia and influenza. Epidemics and pandemics are extremely dangerous and should be taking seriously. But, there are also things that could be done that are and should be being done.
A Pandemic is a disease spreads around the world. An epidemic is when a pandemic spreads rapidly. The epidemic and pandemic is a world issue that kills millions of people a year. One of the diseases that is the hardest to cure is AIDS. AIDS is all around the world and it has lasted thirty four years. AIDS is a sexually transmitted disease that has affected millions of people and scientist are still working to find the cure.
Overpopulation is affecting pandemics and epidemics by the diseases spreading to more people and killing more people. Then more people go through the lose of a relative or friend. Overpopulation is also affecting epidemics and pandemics by when scientists and doctors finally find a cure they have to cure more people and, ...
...influenza pandemic in one way or another; the use of quarantines were extremely prevalent among them. Also, the pandemic is directly responsible for the creation of many health organizations across the globe. The organizations help track and research illnesses across the globe. The CDC (Centers for Disease Control and Prevention) for example, strive to prevent epidemics and pandemics. They also provide a governing body with directives to follow in case an outbreak does occur, and if one shall occur the efforts of organizations across the globe will be crucial for its containment. It is amazing that with modern medicine and proper organization that influenza still manages to make its appearance across the globe annually.
This Radiolab podcast talks about how the HIV/AIDS epidemic started: the ultimate patient zero story, a very recent event that still hurts and still bleeds.
The outburst spread of diseases in a population causes people to panic and become hopeless. The main reason diseases spread is due to unsanitary living styles. Also when a disease first begins, it is really hard to find a cure right away. A very deadly, infectious disease known as Typhus spread during the Holocaust. Typhus is caused by rickettsia and is spread by lice and flees.
The Great War rages on. An influenza epidemic claims the lives of several Americans. But, the Boston Red Sox have done it again. Last night, in a 2-1 victory over the Chicago Cubs at Fenway Park (thanks to Carl Mays' three-hitter), the Boston Red Sox won their fifth World Series championship--amid death and disease, a reason to live ... Babe Ruth and the 1918 Red Sox. If I die today, at least I lived to see the Sox win the championship. For, it could be a long, long, time before this happens again.
migration throughout all of Europe and even America (Forsyth). Efforts to contain both diseases were entirely unsuccessful. AIDS is now an international problem as was
(SIP-A) The plague had many ways in spreading its disease making more and more people get sick very rapidly (STEWE-1) .The plague killed roughly half of the population of Europe, In crowded areas people could receive the Plague from fleas that had bitten wild black rats. Once transferred from flea to human it became fatal in days. (S3 27). (STEWE-2) In 1347 many sailors that were dying from the plague were on Italian merchant ships from the Black Sea, which is on the trade route between Europe and China. Within days the sailors on the ship had spread the plague from the port cities to the surrounding countryside, within a year the disease spread as far as England. (S14). (SIP-B) Because of the rapidly spreading disease the mortality rate and decrease of population was very high and greatly affected those who survived. (STEWE-1) Over half of the population had died and extremely quickly, there were so many bodies that there was no more room to bury them, the brutal depopulation is almost unimaginable for those who lived through such a painful time. (S1
The Influenza virus is a unique respiratory viral disease that can have serious economic and social disruption to society. The virus is airborne transmitted through droplets release by coughing or sneezing from an infected person or by touching infected surfaces. Symptoms range from mild to severe and may even result in death. People with the virus usually experience fever, headache, shivering, muscle pain and cough, which can lead to more severe respiratory illness such as pneumonia. People most susceptible to the flu virus are elderly individuals and young children as well as anyone whose health or immune system has been compromise. The most effective way to counteract the influenza virus is to get the flu vaccine which is available by shots or nasal spray before the flu season as well as practicing safe hygiene. (CDC, 2013)
The influenza or flu pandemic of 1918 to 1919, the deadliest in modern history, infected an estimated 500 million people worldwide–about one-third of the planet’s population at the time–and estimates place the number of victims anywhere from 25 to 100 million. More than 25 percent of the U.S. population became sick, and some 675,000 Americans died during the pandemic. The 1918 flu was first observed in Europe, the U.S. and parts of Asia before swiftly spreading around the world. Surprisingly, many flu victims were young, otherwise healthy adults. At the time, there were no effective drugs or vaccines to treat this killer flu strain or prevent its spread. In the U.S., citizens were ordered to wear masks, and schools, theaters and other public
Pandemics, once started, are expected to spread worldwide. They cannot be stopped from spreading, once they outbreak, they continuously spread. The Black Death was a disease that spread throughout the Mediterranean and Europe. There were approximately 25 million deaths in Europe alone. The Black Death was caused by the bacterium called Yersinia Pestis during the 13th century. The Black Death, also known as the Bubonic Plague was caused by a single contamination of one person. The Black Death was caused by a single bacterium, overcrowding in areas like Europe, which effected a huge part of the population by simply killing it off.
Before I go any further, I feel that I should clarify the difference between the terms epidemic and endemic disease. An epidemic disease is a disease that enters into a population and completely ravages it. Epidemics are particularly destructive because they are usually diseases that have never been introduced into that specific population. A good example of an epidemic is the bubonic plague, or smallpox. Smallpox uncontrollably ravaged Europe for more than two hundred years....
One of the most virulent strains of influenza in history ravaged the world and decimated the populations around the world. Present during World War I, the 1918 strain of pandemic influenza found many opportunities to spread through the war. At the time, science wasn’t advanced enough to study the virus, much less find a cure; medical personnel were helpless when it came to fighting the disease, and so the flu went on to infect millions and kill at a rate 25 times higher than the standard.
However, they have not always been the leading diseases. Around as early as 542 AD, a deadly disease broke out in Constaniople and quickly spread around the world within a few hundred years. This disease in considered the worst natural disaster in history. The Bubonic plague, also known as the Black Death, is historically the disease that has caused the most deaths and caused China, Europe, and India to shortly stop trade altogether. History has been filled with many disasters.
The human population has a high susceptibility to the contraction of new diseases and outbreaks of these diseases are of high risk. Diseases in recent times that have broken out into the human population are the H7N9 flu strain and SARS. Despite the risk, outbreaks like H7N9 and SARS have been controlled due to epidemiology and other disease control methods. Outbreaks of disease are not uncommon to the human population as they move to new areas around the world with foreign diseases that the native residents would have developed a resistance to.
Throughout history many different diseases have infected the world. Such diseases consist of measles, mumps, malaria, typhus and yellow fever. Many of these diseases are caused by different things and originated in different countries.
HIV/AIDS has become a pandemic virus because of how quickly it has spread throughout the entire world. HIV stands for Human Immunodeficiency Virus, which means that it is a virus that attacks the immune system and it can only infect humans. HIV are like other viruses but there is an important difference, overtime your immune system can clear most viruses out of your body. HIV is different, the human immune system can’t get rid of it and scientist are still trying to figure out why our immune system can’t clear it. HIV hides in your body for long periods and it attacks a key part of our immune system, your CD4 cells or T cells. CD4 cells are a type of white blood cell that circulate around our bodies, scanning for cellular abnormalities and infections (www.tcells.com). Which your body must have to fight the virus. AIDS stands for Acquired Immuno Deficiency Syndrome, which means that AIDS is the cause of a different virus, which is HIV. Over 2.5 million people are infected with HIV worldwide. HIV/AIDS can be so deadly to humans because of the viruses capability if attacking our immune system. When HIV replicates itself ...
