Symptoms And Symptoms Of The Flu Virus

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).

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 is well-defined as a minor, but commonly epidemic disease that occurred in several of ways, also caused by numerous of rapidly mutating viral strains. It characterized by the respiratory symptoms and general prostration. The Spanish flu was not a normal epidemic, it was a dangerous pandemic. Epidemics affect individuals at the same time in areas where the disease does not normally spread. A pandemic is an epidemic on a national, international, or global scale. The Spanish flu was different from a usual flu in one big great terrifying way, which had a remarkably high death rate between healthy individuals around the age fifteen to thirty four. There has been such a high death rate in this type if age group in an epidemic prior to or since the Spanish flu of 1918.

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.

First, “Flu Facts” are the most important topic in “Spanish Flu,” because people need to understand how important the flu is. “Influenza, or flu, is a virus that attacks the respiratory system, and is very contagious” (“Spanish Flu”). A infected person can transmit the virus by air and can be inhaled by peers. The virus can be easily transmitted by a person who touches something with the virus on it. “Flu outbreaks happen every year and vary in severity, depending in part on what type of virus is spreading” (“Spanish Flu”).

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

One can claim that influenza is an infection that has victimized people from just about every generation that we have known. The term Influenza comes from the Latin word "influentia", first used by the Italians in the 1600's. It is a highly contagious infection particulary of the respiratory tract.In addition to us humans, influenza can occur in pigs, horses, and several other mammals as well as in certain wild and birds. It can also jump from specie to specie as observed in late 1997 when influenza from chickens was having its effects on people in Hong Kong. Because influenza is highly contagious and spreads easily, it has appeared in our history many a times as epidemics. Influenza is caused by an

According to the Centers for Disease Control and Prevention (CDC, 2013) national healthcare disparities report for 2010, influenza and pneumonia are ranked within the top ten major causes of death in the United States. The influenza viruses that will be discussed throughout this case study include the human influenza viruses: A and B. These viruses are responsible for seasonal epidemics during the fall and winter around the globe in temperate environments. Historically influenza outbreaks have had a seasonal distribution and characteristic time course although according to the CDC (2017) factors influencing the extent and severity of an outbreak are less clear. Generally, there are two or three different influenza strains typically circulating concurrently in any given

Influenza, normally called “the flu”, the influenza virus causes an infection in the respiration tract. Even though the influenza virus can sometimes be compared with the common cold. It also can cause a more severe illness or death. During this past century, pandemics took place in 1918, 1957, and 1968, in all of these cases there where unfortunately many deaths. The “Spanish flu” in 1918, killed approximately half a million people in the United States alone. It killed around 20 million worldwide. The “Asian flu” in 1957, in the United States their 70,000 people died. In 1968 the “Hong-Kong flu” There where 34,000 deaths in the United

The flu has a number of common names which include “English Sweat,” “Grippe,” “Influenza,” and “Swine Flu.” It is a very tiny virus with a diameter of 80-120

People can get the flu, when a carrier with influenza coughs, sneezes or breathes, out tiny, droplets of virus moisture. The droplets enter into other people 's nose and mouth, which then move into your lungs. Once in your lungs, the H-spike on the droplet lands on a receptor molecule on your healthy cell membrane, this fits like a key in a lock. This means the virus can now go into your 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

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
