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 …show more content…
The mode of transmission is droplet because influenza is transmitted by saliva and sneezing. The Influenza disease is primarily spread on to the person by the air. The virus particles are sent into the air when a person with Influenza sneezes or coughs and spread in the middle of the air. The location of the Influenza disease is anywhere in the world. Also, the Influenza disease is mostly found in New Jersey during late November through early April. The peak season of Influenza occurrence is during January and February. But, Influenza is a worldwide disease that can occur the anyone in this entire world. So Influenza can even happen to you caused by the fact that Influenza is a worldwide disease and it can happen, anyone, no matter what age. The Influenza disease is Pandemic which means it is a disease that widespread over a whole country or even the entire world. So anyone in the entire will be able to have the Pandemic disease of Influenza which is widely spread around the whole entire world, it won’t matter where you are there is a chance that you could be one of the Influenza victims. This outbreak disease affects everyone in the world. Influenza and flu are the same diseases because the flu is caused by the Influenza virus. However, there are other viruses that can cause an illness that is similar to the flu. It is difficult to say exactly which virus is causing the illness so doctors diagnosed a flu-like
According to Center for Disease Control (CDC), influenza viruses are divided into three types, designated as A, B, and C. Influenza type C usually only causes either very mild symptoms or no symptoms at all. Types A and B, however, are responsible for epidemics of respiratory illnesses that can result in hospitalization, or even death. Influenza is constantly changing over time by mutations. This continual change allows the virus to evade the antibodies that were meant to kill it. A host infected with influenza virus develops antibodies against that virus; as the virus changes, the "first" antibody no longer recognizes the "newer" virus and infection can occur because the host does not recognize the new flu virus as a problem until the infection is well under way. The first antibody developed may, in some instances, provide partial protection against infection with a new influenza virus. According to Medicine Net.com, In 2009, almost all individuals had no antibodies that could recognize the novel H1N1 virus immediately. It quickly spread throughout the world so fast that the WHO declared this new flu strain (termed novel H1N1 influenza A swine flu). There are currently four main strains of influenza circulating worldwide. Three of the viruses are type A, and one is type B. Type A viruses are divided into subtypes based on the differences in two viral proteins called hemagglutinin (H) and neuraminidase (N). The three subtypes of influenza A are A(H1N1), A(H3N2), and A(H5N1). The reason for several strands of type A are because of the two kinds of change influenza A
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.
First of all, the name “Influenza” is derived from the Latin word for “influence”, and it is an infectious disease that is caused by the RNA viruses from the Orthomyxoviridae family:
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
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, 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.
Among the easiest ways to protect yourself from influenza every year is to get a flu vaccine regularly. So many programs exist to make it convenient and inexpensive, and more come out every year, and the consequences can be life-threatening.
This research paper covers the basic history of influenza. It begins with its early history
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.
There are three types of the influenza virus: Type A, B, and C. Types A and B are contracted and spread by human-to-human transmission.
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
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
With a huge number of victims, 80 to 100 million, since 1918, the influenza is considered as one of the most pandemic diseases ever. There are three types of influenza virus: influenza virus A, influenza virus B, and influenza virus c. These are a subtypes of the virus family orthomyx-oviride. The types B and C do not cause pandemic diseases while type A does. The type A classified into three main subtype H1.N1, H1.N2, and H3.N2. The (H.N) refers to the two kinds of proteins on the surface of the virus (hemagglutinin and neuraminidase). The difference in numbers is due to the difference in protein variability. A H1.N1 virus which is widely known as Spanish flu is the only type that can transmit from human to human. The H5.N1, or “bird flu”
