Essay On Influenza Virus

Influenza, also known as the flu, is a highly contagious viral disease that affects the upper respiratory tract. Flu season typically lasts between the months of October and April. Signs and symptoms include fever, cough, sore throat, muscle aches, fatigue, runny nose, and headaches. Individuals that are at a high risk of getting the flu include: children under the age of two, persons 65 and older, pregnant women, and persons with a chronic illness. Environment factors can also increase the risk of contracting the flu. Complications can include pneumonia, ear and sinus infections, dehydration, or worsening of chronic medical conditions. The influenza virus could eventually lead to longer hospitalization or death if left untreated. According to the CDC, the best way to prevent the flu is by getting vaccinated each year. Compliance with the vaccination is also important in preventing the flu.

Influenza is among the most prevalent infectious airborne viral diseases that affect the respiratory system. According to the World Health Organization (2016), the infection majorly affects the throat, nose, and the bronchi, and on rare occasions, it may affect the lungs. Also commonly known as the flu, influenza infection is characterized by sneezing, itchy and running nose as well as throat inflammation. The initial signs and symptoms include fever with temperatures higher that 100F, soreness in the back, myalgia, legs and arm muscles, sweats and chills, frontal or retro-orbital headaches, tachycardia, red, watery eyes, and fatigue. Sometimes, a dry and persistent cough, nasal congestion and discharge occur

Influenza, also known as “the flu,” is a virus that infects the respiratory tract. Although Influenza is not as severe as many viral infections it's almost the worst for viral infections of the respiratory tract. Typically, when someone is infected with influenza they experience fever (usually 100° to 103°F in adults, but even higher in children) and causes a cough, sore throat, runny or stuffy nose, and also headaches, muscle aches, and usually extreme tiredness. There are sometimes other symptoms such as nausea, vomiting and diarrhea but usually only in rare cases with young children. One other note: The term “Stomach flu” isn’t really caused by 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.

Influenza has many symptoms to help your immune system fight the Flu virus. Influenza has an extremely rare chance of killing its host since we are so immune to it. Influenza is not a serious virus so you should recover from this virus in under two weeks. This virus will attack “mainly your nose, throat, bronchi, and occasionally, lungs” (Influenza). Influenza is non-life threatening.

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

7 Influenza transmit through respiratory droplet from an infect individual. When we come into contact with infections, our symptoms can be caused by two sources: the particular pathogen we are victim to and our immune response against the pathogen. The specific pathogens that enter our bodies can directly cause damage to our tissues and organs; certain pathogens can even affect various parts of our body, causing systemic infections. Systemic infections are caused by our own immune response, designed to destroy the pathogen, such as cytotoxic T-cells action cause Cell death in respiratory track. Our immune system reacts to the presence of the pathogen, and inflammatory response that causes collateral damage to our own tissues while

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

The flu is a viral infection that in the upper or lower parts of the respiratory system. This disease effects the exchange of vital substances by making whoever has it get a fever, a generalized weakness and pain in the muscles.

The flu, formally known as influenza is a contagious respiratory illness that is caused by the influenza virus. The symptoms

There are different ways a molecule can be endocytosed into cell. Rust and colleagues focused on two different mechanisms: clathrin-mediated endocytosis and clathrin- and caveolin-independent endocytosis. Using real-time visualization of the influenza virus, Rust and colleagues were able to observe these two pathways in action. They hypothesized that without inhibiting endogenous endocytic mechanisms of the cell, the influenza virus would use both types of pathways to enter a cell.

Influenza is an infectious illness that can be spread from one individual to the next. It can be transmitted by means of saliva, nasal secretions, feces and blood. It can also be spread by coming in contact with the virus on contaminated surfaces. Influenza is responsible for an average of 36,000 deaths and for more than 226,000 hospitalizations each year in the United States. (Davidson, 2007-2009, Davis, 2007).

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.

(Silverstein: 13) There are three types of influenza, depending on their activity: type A, which is usually the cause of outbreaks; type B, which is linked to sporadic cases, and type C, which rarely causes disease reactions. (Silverstein: 54) The virus which causes influenza enters the host through the respiratory tract, and binds itself to epithelial cells. The virus causes the cell to engulf it by endocytosis, and then fuses to the wall of the endocytic vesicle, injecting the contents of the virus into the cytosol of the cell. The RNA of the virus enter the nucleus of the cell, and spur the creation of new copies of the genes. These genes, as well as new viral proteins that are created in the cell, leave the cell as fresh viruses, budding off the plasma membrane of the cell.

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
