Influenza Virus Family

1. A 2014 study showed that flu vaccine reduced children’s risk of flu-related pediatric intensive care unit (PICU) admission by 74% during flu seasons from 2010-2012. (CDC)

They view proteins created by infected cells, and are sent to other cells to start them making protective substances. Influenza, commonly known as the flu, is a very contagious disease caused by a virus infecting many part of our bodies including the reparatory tract. The influenza virus depending on the sternness usually includes: fever, cough, sore throat, headache, stuffy and running nose, muscle soreness and fatigue. It also can include vomiting, diarrhea, and nausea.

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.

Influenza is a common illness in children. Seasonal influenza especially affects children in childcare and schools and school-age children facilitate the spread of influenza within schools, households, and communities. Influenza spreads mainly from droplets made when people sneeze, cough, or talk. Since droplets can travel 30 feet, all children in a classroom are potentially exposed. Influenza is highly contagious and can spread from person to person even before symptoms appear and can be contagious for a week after symptoms appear. Children are most vulnerable to infection and the hospitalization rate of influenza is highest in young children. Influenza outbreaks not only cause thousands of deaths, they lead to complications such as otitis media, sinusitis, and pneumonia. One study showed that influenza vaccination reduced children’s risk of

Throughout the years, humanity has created vaccines, a form of preparation used as a preventive inoculation to give immunity against any specific disease. The brave souls that put their lives at risk helping the injured, infected and preventing the spread should have the best form of defense when working. One simple and inexpensive defense would be to utilize the vaccinations that are created. The influenza vaccination should be mandatory for all healthcare workers who continue in their line of work.

Most people perceive “the flu” to be a common (not a big deal) illness, but they overlook the 20,000 deaths and over 100,000 hospitalizations nationwide.

Influenza is a highly contagious flu that is a viral infectious virus of the respiratory organ. Orthomyxoviridae is the scientific name of the Influenza virus. Some examples of the influenza virus are Influenza A, Influenzavirus B, Influenzavirus C, Bourbon virus, and Isa Virus. The types of flu A, B, and C are responsible for nearly all the Influenza disease that occurs almost every winter. Infection with type C influenza usually causes either a very mild respiratory illness or no symptoms at all. Infection with type C Influenza are usually caused by either a very mild respiratory illness, or there would be no symptoms at all. The most common host for Influenza is any ages in any lifetime. The symptoms of Influenza are fever, cough, and

Influenza is caused by an RNA virus from the Orthomyxoviridae family (that consists of the genera influenza A, B, and C). Human influenza A and B viruses cause seasonal epidemics almost each winter within the United States. Influenza type B infects humans only, therefore it is unable of undergoing a mutation. Pandemics are caused solely by influenza A strains. The emergence of a new and completely different influenza virus to infect people will cause an influenza pandemic. Influenza kind C infections cause a mild respiratory illness and aren't thought to cause epidemics (Duncan, 2013).

Influenza is an acute condition that results in high fever, a dry cough and sore throat, body aches, headache, runny nose and malaise upon contracting the influenza virus (1). These symptoms often progress into more severe conditions and in certain populations; infection with influenza can lead to death. The influenza virus is an RNA virus that belongs to the family orthomyxoviridae. There are three types of influenza virus and they are classified as type A, type B and type C (2).

Influenza is a life threatening illness caused by influenza virus. It is a contagious disease of the respiratory tract causes serious infections and death around the globe usually in winter season. There are three types of influenza viruses infect humans, type A, B and C. Influenza A and B cause severe disease and major outbreaks and can be prevented through influenza vaccination. Influenza C causes common cold like illness among children. Influenza A is responsible for influenza pandemics. Influenza A and B viruses have two main proteins on the outside of virus, the haemaglutinin (H) and the neuraminidase (N) proteins and are referred as antigens as they are the structures to which our immune system responds. New strains of influenza A and B continually form because the H and N antigens change.

Influenza also known as the “Flu” is an ongoing health concern each year. It is most prevalent during the fall and winter seasons. Influenza is highly contagious and can spread rapidly when precautions are ignored. Every year numerous cases erupt despite education, health promotion and vaccinations. Flu related complications result in hospitalizations and even death each year, costing billions of dollars to be used in treatment and income lost due to sick days and unproductivity on the infected person’s behalf. Zimmerman et al. 2010 concurs stating, “Seasonal influenza leads to about 36,000 deaths annually in the United States and more than 226,000 hospitalizations.” (Zimmerman et al. 2010). Loerbroks et al. 2012 also states “Influenza and

Another way to contract influenza is through fomite (an inanimate object that can carry infectious disease). This is another reason why influenza is so deadly. It’s difficult to tell whether a surface contain the droplet of those infected by the virus and it’s extremely easy to create these surfaces whether by accident or on purpose. People can also spread the flu virus before showing any actual symptoms relating to the flu. Once the influenza virus enters the system, it attaches to the epithelial cells in the bronchi and trachea. The virus then goes into the lytic cycle and the end result being the destruction of the host’s cells. Symptoms of the flu includes sore throat, fever, heavy coughing, and headache. Most people often recover from the flu within one or two weeks but being affected by the flu can also lead to some fatal complications. One of the most prominent complications from the flu is pneumonia (liquid in the lung). This most often affect children and the elderly. People with ongoing diseases are also heavily affected by the flu since it weaken their immune system allowing whatever ailment to achieve maximum lethality. The flu virus weaken the immune system by forcing both antibody and cellular responses to attach to hemagglutinin and neuraminidase in an attempt to neutralize them. Since they both can evolve so rapidly, the task of completely neutralization can

Hello Sherri, influenza was one of my clinical diagnoses based on the patient’s clinical symptoms of fever, fatigue and body ache. Influenza is an acute viral respiratory illness that impact the health of many individuals, families, and communities. Influenza viruses belong to the Orthomyxoviridae family and are enveloped, segmented, single-strand RNA viruses. They can be divided into three types, A, B, C and are varied by viral RNA segments. Types A and B are common and are more likely to cause severe symptoms and epidemics. Seasonal influenza results from circulating influenza A and B viruses. Influenza viruses enter human hosts through columnar epithelial cells of the trachea, bronchi and bronchioles through influenza hemagglutinin, which

Influenza, more commonly known as the ‘flu’, is a chameleon like infectious disease, that presents itself with varying characteristics from year to year, due to the wavering identity of the strain. “Like HIV, influenza is an RNA virus, constantly changing its appearance and adept at eluding recognition by the human immune system” (Schneider, 2014). From its inception of 1918, influenza claims an average of 250,000 to 500,000 people worldwide, annually. Little is known of the virus’s origin however; recent studies examined pathology specimens belonging to deceased soldiers of 1918, revealing similarities with that of the avian flu virus (Schneider, 2014). Evidence has correlated a pattern of influenza strain elements, accompanied by consistent transmutation, that has established a paralleled relationship between that of animal reservoirs and Asia. It is believed that global transmission of the virus is carried via birds that consume food from the same sources that of pigs, consisting of contaminated feed and waterfowl. “Human and animal influenza viruses incubate in a pig’s digestive system, forming new genetic combinations” (Schneider, 2014). Asia occupies cohabitation of the two species that yield fertile breeding grounds for a virus to manifest, while posing a significant threat and concern to the heavily populated areas within close proximity.

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
