Symptoms And Symptoms Of Influenza

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).

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 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

This essay will outline the mechanisms by which the body defends itself against the Influenza Virus, more commonly referred to as ‘Flu’.

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,

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.

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.

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

NoV genogroup GII, particularly strains within the GII.4 lineage, have been globally identified as the predominant cause of outbreaks and sporadic cases of gastroenteritis in the last decade (67). Since the 1990’s, GII.4 strains have undergone mutations and antigenic shift leading to the emergence of novel variants every 2-3 years, that have the ability to cause global epidemics (68). This epochal style of evolution of NoV characterised by periods of stasis followed by the emergence of new variants causing worldwide epidemics is similar to that of the influenza virus (16, 69). Although, GII.4 variants were recognized as having pandemic potential from 1995 onwards, the first GII.4 strain was submitted to the GenBank database in 1974 (43).

There are a lot of symptoms that may affect patients such as coughing, chills, body aches and diarrhea. They vary by the immune status and the age. These symptoms help the doctor to diagnose H1N1 influenza but sometimes it might be hard to diagnose influenza because the clinical signs and symptoms could be the same as other diseases. However, the doctor can make sure that by performing a laboratory test, that will help figure out the cause of the flu virus. The doctor will swab your nose or throat so he or she can take sample fluid from your body in order to make a diagnosis. The swab will be used in various genetics testing and laboratory techniques to identify the specific type of virus

Influenza, or flu, is an infectious disease caused by the influenza virus affects the respiratory system of a living organism. Influenza is a major cause of sickness and death around the globe and propose a major problem to the world today, The fast mutating virus cause flu outbreak every year. The outbreaks are usually frequent within the mid fall season into spring. According to the Centers for Disease Control and Prevention (CDC). In a year, more than 200,000 Americans are hospitalized for flu-related complications, and also that there has been approximately 3,000 to 49,000 flu-related deaths in the U.S (18 Mar. 2015). Since the discovery of the influence virus more than 10 decades agoJ.S. Koen, a veterinarian, Biomedical scientist have studied the virus and had came up

After separating the list of biological agents, most if not all biological agents produce flu-like symptoms. According to Clopton (2017), most illnesses produce flu-like symptoms. Given the incubation period for influenza is seven to ten days it can be too late if people decide to wait to be treated thinking that they have influenza. Thankfully, influenza can be diagnosed

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

People develop a flu-like illness, including fevers and respiratory symptoms. The virus causes inflammation in the cells that form in the lining of the body’s small blood vessels, particularly those in the brain and the lungs. The virus predominantly infects the cells which form the inside layer of blood vessels. Infection can cause small blood vessels, which supply oxygen to the body, to become

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
