The flu (influenza) is a highly contagious virus that attacks the respiratory system. The flu has three strains, H1N1 strain, H3N2 strain and influenza B strain. The first known case according to UXL Encyclopedia of Diseases and Disorders “The first influenza pandemic that is known to have been global in scale took place in 1850; it started in China and spread across central Asia to Africa and then to Europe where it nearly wiped out the populations of several major cities in southern Italy and Spain”. The number of cases in the U.S. and worldwide is according to www.cdc.gov “There has been 11,965 laboratory-confirmed flu-related hospitalizations.” The number of cases in the US and world wide per year is 3-5 million. The type of infection
The Great Influenza is a book not many enjoy. However, Dr. Petri enjoys this book for reasons that are lost to many. The book starts off on part one chapter 1 the Warriors. it starts off with imagery of September 12, 1876 talking about it crowd in an auditorium in Baltimore’s Academy of music. this was too launch John Hopkins University where they say they would change all of American education and in this first page you meet Thomas H. Huxley an English scientist who is the keynote speaker of this event. then give me George Armstrong Custer who “led the seventh Cavalry to with the stretching at the hands of him video savages resisting encroachment of the white man.” customer had spoke on the front page of the Washington star. then the book starts going deeper into detail
Influenza: By Abbey Stansborough What part of the body does it effect: Influenza effects almost all of your body but the most common parts that cause the most pain are your head lower back and legs, there is different types of pain so it isn't the same pain everywhere. Symptoms: Some of the symptoms are: Chills Aching behind the eyes Loss of appetite Sore throat Runny/stuffy nose Sudden appearance of high fever Dry cough Body aches Felling weak and tired These are the symptoms that most people have and they are the most common but everyone is different and some people Causes or attributing factors to the disease: The most common way to catch the flu is by touch or if you come in contact with someone who already has the flu. There are also many
The 1918 influenza had a catastrophic impact on the world. It washed over the world in waves, killing millions from even the most remote places on every continent. No one was safe from this lethal disease. It also had an odd pattern in victims that nobody had seen before, killing strong and healthy people. It was a ruthless disease that devastated it’s victims and killed them in a macabre way.
The Spanish influenza, also known as La Grippe, Spanish Lady, three day fever, purulent bronchitis, sand-fly fever and Blitz Katarrh (The 1918 Influenza Pandemic) was a global disaster which occurred between March of 1918 and the spring season of 1919 (The 1918 Influenza Pandemic). This virus was more catastrophic even than the First World War which was occurring at the same time the influenza broke out, killing more people than the Great War itself (The 1918 Influenza Pandemic). The virus killed more people in one year than in the four years of the Black Death Bubonic Plague (The 1918 Influenza Pandemic). Many questions about the flu’s origin and its nature remain largely mysterious to epidemiologists and scientists alike. (1918 Influenza:
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 A is a highly contagious infection of the respiratory tract that affects all ages. The infection is highest among children and the frequency of serious illness and death is greatest among older adults, over 65 years old. Influenza often is a self-limited disease, subsiding without therapy. It comonly occurs in outbreaks, mainly in the winter months.
The virus has been studied in detail during 2009-2010. Being a complex virus, it is important to study the current scenario and the trends of the circulating virus. During 2015, the incidence of pandemic H1N1 2009 influenza virus among patients presenting with ILI, diagnosed in our tertiary care hospital during the study period was 18.6%. In the 2012-2013 the incidence of pandemic H1N1 2009 influenza virus among patients presenting with ILI, was 8.20% indicating a sharp increase in the number of cases. 9 After 2010, the 2009 pandemic H1N1 influenza A reappeared in several northern and western states of the country during the winter months of 2012-2013. The presently ongoing resurgence since December 2014 however appears to be worse than the previous one, leading to over 30,000 cases and 2000 deaths countrywide (as of 28th March,2015) as compared to 5044 cases and 405 deaths in 2012 and 5250 cases and 692 deaths in 2013.10 The resurgent waves lead to more number of hospitalizations and deaths due to pdmH1N1 as compared to the rest part of the year and appear at an interval of 1.5-2
Throughout the history, influenza viruses have caused several pandemics or global epidemics, killing many people. For example, the influenza strike in 1918 to 1919 infected an estimated 500 million people worldwide, which is one-third of the planet’s population at the time and killed an estimated 20 million to 50 million people. More than 25 percentage of the U.S. population were affected, and caused 675,000 deaths in U.S during the pandemic.(History, 2015). There were no effective treatments for this type of influenza and no available vaccines can prevent its spread during the period. (History, 2015) U.S government required general population to wear masks and other protective equipments in public areas, and many public places also closed due to the influenza strike. Health care providers tried everything they knew to save people, but none shows any evidence of effects. (National Center for Biotechnology Information [NCBI], 2015). Scientists found out that the influenza virus had invaded their lungs and caused pneumonia, which made so many people died from the pandemic (History,2015). Another influenza strike happened
According to History.com, a well-known historical record website, on March 11th 1918, a U.S. Army soldier reported cold-like symptoms consisting of sore throat, fever, and headache. By the noon of that same day, over 100 other soldiers reported the same symptoms. This would grow into the first-known outbreak of influenza in the world, infecting 500 million people worldwide, and killing over 20 million people. Robert Krulwich, a scientific correspondent for NPR, explains the process by which a virus enters your body and manifests into something much worse: The influenza virus first enters your respiratory system by inhalation or other, less-common methods. The virus is then expelled into your bloodstream where it latches onto a cell found there.
Paula Sullivan, a seasoned nurse practitioner, discusses how influenza is an infectious disease that takes place “in temperate regions around the world” which results in approximately the death of 500,000 people “annually” worldwide; 226,000 people get hospitalized and 36,000 die from influenza annually in the United States alone (Sullivan). Most of the people who die from the influenza virus are aged 65 years or older and that is usually because other diseases are
citizen avoided another, hardly any neighbour troubled about others, relatives never or hardly ever visited each other. Moreover, such terror was struck into the hearts of men and women by this calamity, that brother abandoned brother, and the uncle his nephew, and the sister her brother, and very often the wife her husband. What is even worse and nearly incredible is that fathers and mothers refused to see and tend their children, as if they had not been theirs.” So many people did not know what the plague was and it made people very afraid. Agnolo di Tura del Grasso produced a chronicle of events from 1300 to 1351 with his experiences with the plague. “And I, Agnolo di Tura, called the Fat, buried my five children with my own hands. And there
It is well known that Influenza was one of the most spread and dangerous diseases in the past. Moreover, it was a fatal epidemic especially in America and Spain, and it resulted in the death of millions in the 20th century. Now, Influenza is not considered as a real life-threatening but it is still a serious illness (1). So, what is Influenza? And what are its symptoms? And how many kinds of Influenza are there? Influenza is a viral disease that infects the respiratory system, and it can be a fatal in some cases (2). Moreover, it has several symptoms and three main types (3).
Influenza, normally called “the flu”, the influenza virus causes an infection in the respiration tract. Even though the influenza virus can sometimes be compared with the common cold. It also can cause a more severe illness or death. During this past century, pandemics took place in 1918, 1957, and 1968, in all of these cases there where unfortunately many deaths. The “Spanish flu” in 1918, killed approximately half a million people in the United States alone. It killed around 20 million worldwide. The “Asian flu” in 1957, in the United States their 70,000 people died. In 1968 the “Hong-Kong flu” There where 34,000 deaths in the United
I´ve been sick before and it's not that fun, but this time I was feeling really sick. I was thinking about asking the teacher to go down to the clinic, but I had a big test and there is no way I am going to miss that test. When I got home that day I asked my mom to take my temperature
In this article, Sun & Metzger (2014) propose the mechanism for influenza- induced predisposition to methicillin- resistant Staphylococcus aureus superinfection. They hypothesize that suppression of NADPH oxidase, an enzyme responsible for the production of intracellular reactive oxygen species during phagocytic bacterial killing plays a pivotal role to enhance susceptibility to secondary MRSA infection. They conduct a mouse model influenza infection experiment followed by S. aureus respiratory challenge to demonstrate impairment of innate antibacterial defense by influenza virus. They find high bacterial burden on influenza and MRSA- coinfected mice as compared to MRSA alone, which infer decreased bacterial clearance capability and survival
