Unbeknownst to us, there is a residing disparity that threatens the very existence of humanity. Something that does not quite yet exist poses a threat to the continuation of human existence as we know it. An unpredictable occurrence of avian influenza (bird flu) strain is the primary concern of public health professionals and health care administrators. The peril of a potential humanized strain of avian influenza outbreak is completely uncertain partly because of the impact which the ecosystem plays in the variance of viruses and the evolutionary structure of bacteria. Although research enthuses imply that the occurrence of an avian influenza is unlikely to appear within our generation, it is still critical to remain vigilant.
The first appearance of the avian influenza is suspected to have emerged in 1878 in northern Italy when Perroncito demonstrated a contagious disease of poultry associated with high mortality (Lupiani & Reddy, 2009). Avian influenza was later defined by Perroncito as “fowl plague,” an acute contagious disease of poultry and other domestic and wild birds (Alexander & Brown, 2009). The highly pathogenic avian influenza became endemic through Italy and Central Europe until it disappeared around the mid-1930s (Lupiani & Reddy, 2009). It was not until 1918 that this highly pathogenic influenza reached the United States. In 1918, the United States, and most of the world was living in fear of an invisible enemy that was rumored to destroy everything in its path. It has been determined that the influenza epidemic of 1918 killed more people than the number of deaths obtained during World War I. One fifth of the world’s population was attacked by the deadly pandemic influenza virus of 1918, killi...

However due to globalization, import and export viruses is more easily transmitted. Over the past century the global community especially Asian has been affected with new strains of the influenza virus. The changes in the virus can occur in two ways “antigenic drift” which are gradual changes in the virus over time. This change produces new strains that the antibody may not recognize. “Antigenic shift” On the other is a sudden change in the influenza virus which ‘’ results in a new influenza A subtype or a virus with a hemagglutinin or a hemagglutinin and neuraminidase combination that has emerged from an animal population,” as seen with H5N1 virus. This change leaves people defenseless against this new virus. (CDC, 2013) Currently there is no vaccine to combat all strains therefore “Planning and preparedness for implementing mitigation strategies during a pandemic requires participation by all levels o...
A few years before 1918, in the height of the First World War, a calamity occurred that stripped the globe of at least 50 million lives. (Taubenberger, 1918) This calamity was not the death toll of the war; albeit, some individuals may argue the globalization associated with the First World War perpetuated the persistence of this calamity. This calamity was referred to the Spanish Flu of 1918, but calling this devastating pestilence the “Spanish Flu” may be a historical inaccuracy, as research and historians suggest that the likelihood of this disease originating in Spain seams greatly improbable. Despite it’s misnomer, the Spanish Flu, or its virus name H1N1, still swept across the globe passing from human to human by exhaled drops of water that contained a deadly strand of RNA wrapped with a protein casing. Individuals who were unfortunate enough to come in contact with the contents of the protein casing generally developed severe respiratory inflammation, as the Immune system’s own response towards the infected lung cells would destroy much of the lungs, thus causing the lungs to flood with fluids. Due to this flooding, pneumonia was a common cause of death for those infected with Spanish Flu. Due its genetic similarity with Avian Flu, the Spanish Flu is thought to be descended from Avian Flu which is commonly known as “Bird Flu.” (Billings,1997) The Spanish Flu of 1918 has had a larger impact in terms of global significance than any other disease has had because it was the most deadly, easily transmitted across the entire globe, and occurred in an ideal time period for a disease to happen.
The influenza pandemic of 1918 had not only altered the lives of thousands, but the habitual lives of family and work as well. The Spanish Influenza collected more lives than all of the casualties of war in the twentieth century combined. After the disease had swept through the nation, towns that once began their days in lazy, comfortable manners had begun to struggle to get through a single day. What started as a mild neglect of a typical fever or case of chills had escalated and grown at an alarmingly rapid rate to be fearsome and tragic.
From the time of its first recorded incident in 412 BC (Adams 1) to 1918, influenza was never taken seriously. With symptoms similar to the common cold, most people disregarded influenza as a minor illness, nothing more. As Lynette Iezzoni quoted in her book, Influenza 1918, influenza was thought to be “quite a Godsend! Everybody ill, nobody dying” besides the very old and feeble (16). However, the influenza virus was out to prove them wrong in the influenza pandemic of 1918.
Influenza is a major public health problem which outbreaks all over the world. Resulting in considerable sickness and death rates. Furthermore, it is a highly infectious airborne disease and is caused by the influenza virus. Influenza is transmitted easily from one person to another person which has a great impact on society. When a member of society becomes sick, it is more prone to spread to other people. In the United States, every year between 5 to 20 percent of the population is affected by influenza. As a result of this, between 3,000 and 49,000 deaths have occurred per year (Biggerstaff et al., 2014). Therefore, the influenza vaccine is the most effective strategy to prevent influenza. This essay will examine two significant reasons for influenza vaccination which are the loss of workforce and economic burden as well as one effect regarding herd immunity.
Influenza is very contagious and spreads rapidly from person to person. Influenza causes worldwide yearly epidemics. According to World Health organization Influenza affects 5-15% world’s population and resulting in 500,000 deaths yearly. Ottenberg stated that, in United States, an average of 200,000 were hospitalized and 36,000 died each year from influenza complications. Influenza is the sixth leading cause of death among US adults and is related to 1 in 20 death in persons older than 65 years. Disease control and prevention estimates indicate that infections like H1N1 which is one of the types of influenza, have resulted in an estimated 42 to 86 million cases and 8520 to 17620 deaths. As I mentioned earlier that infections like influenza are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)
In the fall of 1918 influenza appeared for the first time in pockets across the globe. At first it was pushed aside as a case of the common cold. The influenza of that season, however, was far more than a cold. In the two years that this scourge ravaged the earth, a fifth of the world's population was infected. (1) Including twenty-eight percent of all Americans. In those two years an estimated six hundred and seventy-five thousand Americans died because of influenza. This was the greatest scare Americans had ever seen from a single disease. People between the age of twenty and forty were at the greatest risk of infection. Even President Woodrow Wilson suffered from the flu in early 1919 while negotiating the crucial treaty of Versailles to end the World War. The public health departments distributed gauze masks to be worn in public. Stores could not hold sales; funerals were limited to 15 minutes. Some towns required a signed certificate to enter and railroads would not accept passengers without them. (1) Influenza had killed nearly as many American servicemen as died in battle, ten times and over that number of American civilians, and twice as many people in the world as died in combat on all fronts in the entire four...

At no time was a search for the cure for influenza more frantic than after the devastating effects of the pandemic of 1918. The pandemic killed somewhere between twenty and a hundred million people, making it twenty five times more deadly than the ordinary cough and sneeze flu. The symptoms of this flu were like something straight out of a horror movie: the victim’s facial complexion changed to a dark, brownish purple, the feet turned black, and they began to cough up blood. Eventually, death was caused, literally by drowning, when the victim’s lungs filled with their own blood. The first scientist to claim to solve the enigma of influenza was Dr. Friedrich Johann Pfeiffer. He isolated a bacterium he named Hemophilus influenzae from the respiratory tract of those who had the flu in the pandemic of 1890. He was believed to be correct in his discovery until the pandemic of 1918, when scientists searched the respiratory tracts of influenza victims and only sometimes found his bacterium. Robert E. Shope and his mentor Paul Lewis were the next to attempt to crack the code of influenza. They chose to study the disease in pigs, a controversial choice because many people believed that the swine influenza pigs were contracting was not the same as the human flu. The first experiment they ran was ba...
The Influenza Pandemic of 1918 had a major effect on the public health in America at the time. Coordination between different levels and branches of government improved communication regarding the spread of influenza, improved the amount of people in hospitals, increased the spread of vaccines, and led to improvements in infection control and containment of the flu. (http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1997248/).
The social effects of the influenza epidemic of 1918 were severe: (1) The medical and scientific communities had to develop new theories and “apply them to prevention, diagnostics and treatment of the influenza patients” (Barry, 234). Something that, until then, no pandemic had forced (or allowed) such a collaboration. (2) In some cities and towns residents were required to wear surgical masks to protect themselves from the virus because influenza can penetrate even tightly woven clothing. (3) Children made up rhymes to jump rope to: Its name was Enza. / I opened the window, / And in-flu-enza. (4) The precautions set by city officials to help minimize influenza’s effects, such as closing schools and churches and limiting commerce, all changed
Throughout 1918 and 1919, influenza spread quickly in three waves killing an estimated 50 million to 100 million people worldwide. With the best-recorded first case having occurred in Fort Riley, the contagious flu spread across military camps around the United States. Due to the world war, the influenza virus was brought over to Europe where it infected people in nearly every country. This disease would end up causing one of the greatest pandemics in human history, but would also catalyze great advancements in science and medicine.
The “Aussie flu”, an Australian influenza virus, has made headlines on media worldwide. It is suggested that the Australian strain has spread to other countries, which has led to criticism of Australia’s Public Health policies. Although, is it possible to identify a strain’s source? If so, how did this “Aussie flu” become so harmful, could it have been prevented? The media is comparing this year’s flu outbreak to the 1968 Hong Kong flu, is it really the next flu pandemic? Influenza viruses are ever evolving and resisting to antibiotic treatment. This is a Global Health issue, particularly making an impact in Australia.
The severity of this occurrence of influenza is most evident with our young folk who have become quite susceptible to this recent "epidemic." Yet, people of all ages, genders and social standings are prone to the illness. No one is safe, unlike the initial reports produced by the Board of Health, which suggested that Americans were impervious to the "Spanish influenza."
In 1918-19 approximately 50 million deaths were a detriment of the Spanish H1N1 virus pandemic; a respiratory virus. According to the World Health Organization, the second Influenza A H1N1 pandemic in 2009 spread to more than 200 countries causing more than 18 000 deaths. Before the World Health Organization had announced the official end of the pandemic in August 2010, in July 2009 the World Health Organization sent out a phase 6 warning that H1N1 could soon be a global pandemic. It is important to recognize that the 2 different outbreaks had different A/H1N1strains effecting the world population; this suggests A/H1N1has a high ability for mutation, severely complicating the human body’s natural immune mechanism of antigenic drift.
