How the Body Defends Itself Against the Influenza Virus

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.

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.

Influenza, also known as the flu, is a contagious respiratory illness caused by the influenza virus that infects the nose, throat, and lungs (Centers for Disease Control and Prevention,

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

The influenza virus is “an acute respiratory tract illness, with outbreaks occuring annually that are responsible for large numbers of hospitalization and death worldwide” (Dool et al. 314-319). The influenza virus has a few common symptoms that

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

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

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.

Describe two innate (nonspecific) immune responses that might prevent an influenza virus from causing any noticeable infection, even if the virus enters your respiratory passages.

Flu season is upon us and influenza has hit our area particularly hard this year. The flu is a contagious respiratory illness caused by influenza viruses that infect the nose, throat, and lungs that spread from person to person through sneezing and coughing. The flu can also be spread surfaces when infected people touch surfaces such as door knobs, shopping carts, computer keyboards, countertops, etc. Symptoms of the flu include fever, cough, sore throat, body aches, headache, chills and fatigue. Though it can be difficult to avoid the flu entirely, there are things you can do to protect yourself and your household from getting the flu by following these steps at home. Continue these steps daily throughout the flu season.

Someone may sneeze or cough and not cover their mouths and another person may come along and inhale those water droplets left behind by the infected person, which will cause them to become infected. Another common route of transmission is when an infected person sneezes or coughs into their hand and touches a surface. A healthy person may then come along and touch the surface then their face, nose, mouth or eyes and then become infected with the influenza. The H1N1’s route of entry and exit is through the mouth and nose. The primary target for this H1N1 virus is the upper respiratory tract in humans. This virus spreads even more quickly among crowded places as well as being able to survive longer outside of the body in cold and dry environments. This specific influenza virus reproduces by the lytic cycle. Once the H1N1 virus has entered the body, it supplements its own DNA/RNA into the body’s cells. This instructs the cell to stop its normal functioning for the body and begin manufacturing the H1N1 virus. This non-living organism “hijacks” our bodies to supply the raw materials it needs to replicate and infect our bodies. Once the infected body cell makes enough viruses, it splits open or lyses resulting in the death of that cell and those new virus particles repeat the cycle, cell after cell until our body begins to fight back which is when we begin to feel the symptoms of the

Infected patients pursue help from their doctors pleading for remedy for their symptom. In turn, doctors had no cure or ways to subdue the patients’ symptoms; thus, it result-ed in getting the doctor themselves falling ill to the influenza. At time, the infected patients felt inflamed and burned with thirst. This resulted the plague victims to plunge themselves in cold water, or throwing themselves in rain tanks to ease the burning sensation . The 1918 influenza produced an unusually high proportion of cases that developed pneumonia, especially in young people. Normally, influenza causes only mild illness in young adults. In 2009 during the spread of the H1N1 influenza virus in the population worldwide suggests that a large portion of the population now have defensive antibodies against the 1918 virus, greatly lessening fear and un-certainties regarding the exposure of the 1918 virus. Nevertheless, study exhibit that this virus could be used not only to understand how to prevent and treat severe influenza virus infections but also to create a biochemical agent

Influenza is one of the most contagious illnesses caused by airborne viruses. I can lead to mild or severe illness and even death. Influenza can come suddenly and is marginally different to a ‘Cold”. The virus can cause infections of the lower respiratory tract (lungs) and the upper respiratory tract (throat, nasal). Influenza is disease that may cause symptom such as the following; fever (high body temperature), sore throat, muscle or body aches, cough, Headaches, runny or stuffy nose, fatigue/tiredness (CDC, 2016). it belongs to “Orthomyxoviridae” family of infections, “myxa” meaning ‘mucus’ in Greek. There are three major types of influenza that may also be addressed as different terminologies, such as flu

Influenza, commonly known as ‘the flu’, is a respiratory disease found in humans and certain animal species this includes pigs, wild aquatic mammals like whales, domestic and wild birds, minks and farmed carnivores (Nicholson, Webster, Hay, 1998). There are three types of influenza viruses type A, type B and type C. Type A virus is the important one as far as cross-species infections are concerned (Nicholson, Webster, Hay, 1998). Types B and C are human viruses that primarily affect young children with mild disease

Background & Audience Relevance: Influenza is an infection that can affect anyone around the world. Am quite sure almost everyone, if not all of us, have been infected with influenza at some point in our lives.
