Case Study Of Influenza

Central/Thesis Statement: Influenza (“flu”) is a contagious disease that spreads around the United States every year, usually between October and May.

Every year, millions of people start talking about the influenza virus and getting their vaccines as the flu season approaches, which starts around the October-November period and reaches its peak between December and March. Therefore, public health officials around the world- and in the U.S in particular- are constantly challenged by properly preparing for the annual influenza dilemma, given that this viruses, and other respiratory viruses, are a serious health threat to the U.S population and the world as a whole. Furthermore, what makes the influenza virus even more challenging to control is that it can mutate rapidly and reassort to form new strains, having the ability to reside in multiple animal hosts. In fact, many scientists and researchers have been doing in-depth intensive research so as to understand the mechanism behind this unique characteristic of the virus, try to find new ways to control it, and explore different areas of protection and vaccination.

This paper will discuss the communicable disease influenza. It will discuss the causes, symptoms, and treatments, as well as the demographics of interest. It will also discuss the determinants of health and how these factors contribute to the development of influenza. Included in this paper will be information on host, agent, and environmental factors. Lastly it will explain the role of the community health nurse in caring for those affected with influenza and the role they play in education and prevention.

This new influenza baffled researchers and doctors everywhere. Up to this point, all viral diseases has spread prominently throughout heavily populated areas and into the lungs of the very young, very old, or sickly. On the contrary, the Influenza of 1918 swept through the Midwest and preyed on the

Influenza is not a deadly virus and does have a vaccination. One of the three types of influenza, type C, “type C infections cause a mild respiratory illness and are not thought to cause epidemics” (Types of Influenza Viruses). The other two types of influenza viruses type“ A and B viruses cause seasonal epidemics” and happen mostly when winter hits (Types of Influenza

According to the Centers for Disease Control and Prevention (CDC, 2013) national healthcare disparities report for 2010, influenza and pneumonia are ranked within the top ten major causes of death in the United States. The influenza viruses that will be discussed throughout this case study include the human influenza viruses: A and B. These viruses are responsible for seasonal epidemics during the fall and winter around the globe in temperate environments. Historically influenza outbreaks have had a seasonal distribution and characteristic time course although according to the CDC (2017) factors influencing the extent and severity of an outbreak are less clear. Generally, there are two or three different influenza strains typically circulating concurrently in any given

Influenza, an innocent little virus that annually comes and goes, has always been a part of people’s lives. Knowing this, one would not believe that it has caused not one, not two, but three pandemics and is on its way to causing a fourth! The Spanish flu of 1918, the Asian flu of 1957, and the Hong Kong

Influenza, commonly referred to as the seasonal flu, is a respiratory infection caused by a virus. Areas

There are there types of influenza A and C or the most severe types and B which is the most common, Luckily not the to severe. The virus works by first attaching to the outside of a host cell. It injects its RNA into the cell. Unfortunately our cells treat the RNA like they should. It translates the viral genes using the cell’s ribosomes and enzymes. Now the virus can take the cell over and use it to reproduce more viruses. Sooner or later it releases the new nauseating viruses and they search for another cell to raid.

Seasonal influenza commonly referred to as the “flu” is an acute viral infection caused by the influenza virus that can have possibly devastating effects on a community (“Influenza (Seasonal),” 2014). Seasonal influenza viruses cause annual epidemics that peak during the winter but can begin as early as late fall and last through early spring (“Prevention and Control of Influenza,” 2008). Influenza infections in the US affect a large amount of the US population. On average in the United States 200,000 people are hospitalized due to influenza infections (“Vaccine-Preventable Adult Diseases,” 2016). In addition, the annual death toll in the United States alone related to influenza and its complications is about 20,000 (Fallon, 2013). Though influenza can affect people at any age, the rates of serious illness and death are among the highest in persons aged sixty-five or older (“Prevention and Control of Influenza,” 2008). The disproportionate effect of the influenza infection on older adults calls for public health interventions.

Each winter season brings the horrid infectious disease, influenza also commonly known as “the flu.” Just in the past week, over 250 cases of positive specimens were gathered with it being the highest week in the year of 2017. Influenza has already been in full force this winter, with many people around Australia falling ill. Everyone in their lifetime suffers from the nasty flu as sometime in their life, but for some, it’s a critical and complicated disease. In the selected years of 2006, 2010 and 2015, influenza was one of the leading causes of death. Influenza and pneumonia are at rank 12, with 2015 having at least 3,402 deaths, more than breast cancer. “There has been a total of 12, 360 laboratories confirmed notifications of influenza

Despite modern medical and public health standards, influenza remains one of the main principal lethal infectious diseases worldwide [1]. Influenza viruses are responsible for an average of 400,000 deaths per year globally [2, 3]. During previous influenza pandemics (H1N1, 1918; H2N2, 1957; H3N2, 1968; and H1N1, 2009) and seasonal epidemics, many cases of influenza virus-related deaths actually occurred due to bacterial co-infections [4-11]. Since the 1950s, researchers have increasingly focused on concomitant infections with influenza viruses and a range of bacterial agents.

Influenza is a droplet infection caused by the virus orthomyxoviridae (1). A virus is a microscopic parasite which is usually much smaller than bacteria and viruses can also make you sick (2)(3). Their cell structure is not organized and do not contain a nucleus. Also most viruses are coated in a protein called CAPSID (4). Influenza reproduces through viral cell replication. This means that the virus will attach onto a host cell and inject its genetic material into it then it now is infected with the virus and this continues throughout all the cells (5). Unlike Bacteria viruses don’t rely on water or food because they do not need to respire. The main condition that they completely rely on is a host cell because without a host cell the virus

Nausea and diarrhea may occur during Uncomplicated acute influenza can cause a persistent dry cough and malaise (feeling tired and lethargic). Complicated influenza can be worsen with pre-existing health conditions, such as pulmonary or cardiac disease that can lead to secondary bacterial pneumonia. Also individuals with underlying blood disorders or neurological conditions can be at high risk. Death can occur with either of these pre-exisiting or secondary conditions. Death results are between 12,000 and 56,000 annually with influenza.

Restate Thesis: Influenza is a common virus that is present in almost every part of the world. Studies show that influenza causes people to be prevalent to other diseases, especially respiratory diseases. According to an article on The Lancet, August 14th, 2009 by Jamieson, the virus caused the widespread outbreak of respiratory infection
