Influenza is caused by an RNA virus from the Orthomyxoviridae family (that consists of the genera influenza A, B, and C). Human influenza A and B viruses cause seasonal epidemics almost each winter within the United States. Influenza type B infects humans only, therefore it is unable of undergoing a mutation. Pandemics are caused solely by influenza A strains. The emergence of a new and completely different influenza virus to infect people will cause an influenza pandemic. Influenza kind C infections cause a mild respiratory illness and aren't thought to cause epidemics (Duncan, 2013).
The influenza virus is transmitted from human to human mainly by droplet, although there are cases of animal to human transmission. The incubation amount is approximately 3 days, although nasal shedding can peak about 24-48 hours once onset of symptoms. Viral shedding starts at intervals 24 hours before the onset of symptoms and continues for up to five days in healthy adults and a number of weeks in immunocompromised patients (Duncan, 2013). It has been shown that both influenza A and influenza B viruses can survive for 24-48 hours on nonporous surfaces like chrome steel. They can survive for 8-12 hours on products like tissues. Prevention should focus on: hand-washing, avoidance of touching eyes and different mucous membranes, cleaning commonly used surfaces, and by covering the mouth and nose when coughing or sneezing (Duncan, 2013).
The most known groups at risk are: elderly individuals (over 65), pregnant women, patient with chronic cardiac, pulmonary, renal, hepatic and neurological disease and diabetics. The common symptoms of influenza are: fever or feeling feverish/chills, a temperature of 38°C (100.4 °F) or above, cough, sore th...

Influenza can be introduced and spread into an extended-care facility by newly admitted residents, health care staff and by visitors. Residents of long-term care facilities may experience severe and fatal illness during influenza outbreaks. Preventing transmission of influenza viruses and different infectious agents inside health care settings, needs a comprehensive approach that includes: vaccination, testing, infection management, and antiviral treatment (Unknown, 2013).
Management of patients in the high risk groups requires early diagnosis and treatment with antivirals. The best course of treatment is prevention of the disease through vaccination and education. Annual influenza vaccination is the first step for preventing influenza and its complications (unknown, 2013).

[1, 4, 5, 9, 13] There have been no documented cases where a human has contracted the disease from another human. [4] It appears, based on field and lab data, that infection requires direct contact with the virus through means such as contact with infective bodily secretions, urine, or tissues. [12] It is unknown to scientists how the virus can be maintained in the bat populations and avoids extinction as the host species becomes immune to its presence. [14] The incubation period from time of infection to the onset of symptoms is about 5-14 days in experimentally induced animals [4] and 8-14 days in natural field cases.
The Influenza Pandemic of 1918-1919 occurred during the midst of World War I, and it would claim more lives than the war itself. The disease erupted suddenly without a forewarning and spread rapidly across the globe. It seemed as though all of humanity had fallen under the mercy of this deadly illness. Influenza had very clear symptoms as described by William Collier in his letter to The Lancet. After a patient seizes their temperature can run up to 105° or more while their pulse averages at about 90 beats per minute. The high temperature and low pulse are frequently combined with epistaxis (nosebleed) and cyanosis (blueness of the skin). The epistaxis is caused by the high temperature and the cyanosis is caused by a lack of oxygen due to the decreased pulse (Kent 34). The author of Influenza Pandemic of 1918-1919, Susan Kinglsey Kent, provides a brief history of the pandemic and documents from the time period. Many of the included documents show how unprepared and unorganized governments attempted to contain and control a disease they had never experienced, and how the expectations of the governments changed as a result of their successes and failures.
After an incubation period of five to ten days, or as long as 21 days, numerous symptoms can be observed. The symptoms come in two stages. The first stage consists of common cold symptoms such as sneezing, runny nose, low-grade fever, and a mild cough. It is during this time that the disease is most contagious, and it lasts from one to two weeks.
The Influenza virus is a unique respiratory viral disease that can have serious economic and social disruption to society. The virus is airborne transmitted through droplets release by coughing or sneezing from an infected person or by touching infected surfaces. Symptoms range from mild to severe and may even result in death. People with the virus usually experience fever, headache, shivering, muscle pain and cough, which can lead to more severe respiratory illness such as pneumonia. People most susceptible to the flu virus are elderly individuals and young children as well as anyone whose health or immune system has been compromise. The most effective way to counteract the influenza virus is to get the flu vaccine which is available by shots or nasal spray before the flu season as well as practicing safe hygiene. (CDC, 2013)
Although people should have the freedom to choose to be vaccinated, the public needs to be educated about the personal, economical, and social benefits of receiving the influenza vaccine. In addition, people who are at a high risk of contracting influenza as well as health care providers should be encouraged to receive an influenza vaccine in order to decrease the major health burden associated with the disease. Influenza, commonly known as the flu, is a viral infection of the respiratory system and it is characterized by abrupt onset of fever, sore throat, and nonproductive cough. Influenza is spread from person to person by inhalation of the droplets produced when a person infected with influenza coughs or sneezes. In addition, it can also be spread by contact with infected objects such as utensils.
While influenza, or the "flu", is not commonly recognized as an extremely lethal disease, the pathology of influenza, and especially of the kind found at Fort Dix, does suggest that an immunization program was a reasonable course to take in 1976. In the public's mind, influenza is often not seen as a specific disease, using interchangeable names for it like "flu", "gripe", and "virus". (Silverstein: 1) However, influenza is very different from an everyday low fever or "stomach flu". It is a respiratory infection, connected with a fever, coughing, and muscle aches, which often la...
The treatment for the influenza virus is to get plenty of bedrest and to drink plenty of fluids. On occasion a physician may prescribe an antiviral medication like Tamiflu or Relenza; but only in the first few days that symptoms arrive. The prognosis for the influenza virus is that most people will recover fully from the influenza virus.
Hospital-acquired infections (HAI) are preventable and pose a threat to hospitals and patients; increasing the cost, nominally and physically, for both. Pneumonia makes up approximately 15% of all HAI and is the leading cause of nosocomial deaths. Pneumonia is most frequently caused by bacterial microorganisms reaching the lungs by way of aspiration, inhalation or the hematogenous spread of a primary infection. There are two categories of Hospital-Acquired Pneumonia (HAP); Health-Care Associated Pneumonia (HCAP) and Ventilator-associated pneumonia (VAP).
Influenza is a major public health problem which has outbreaks all over the world. Resulting in considerable sickness and death rates. Furthermore, it is a highly infectious airborne disease and is caused by the influenza virus. Influenza is transmitted easily from one person to another person, which has a great impact on society. When a member of society becomes sick, it is more prone to spread to other people.
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 are very contagious, they can spread easily from hcw to Patient and back to hcw. The most efficient and effective method of preventing influenza infection is vaccination(The best way to prevent influenza is with annual vaccination).(Sullivan,2010) (Gregory,Tosh &Jacobson, 2005). Motivated by a desire to actively avoid illness Influenza may increase the risk for death in people with existing heart, lung, or circulation disorders. In fact, the higher than average number of winter deaths in people with heart disease may be due only to the occurrence of influenza during those months.Vaccination provides immunity to fight against infection.To increase resistance to harm by modifying the environment to minimize preventable illness (NEED TO CHANGE WORDING)
Illnesses have long haunted the human race. As long as these illnesses have existed, humans have developed ways to cure themselves, beginning with simple herbs and proceeding as far as vaccines and complex medicines. One cure that long eluded scientists was that of the influenza virus. Now, the influenza vaccine, or flu shot, saves thousands of lives a year and helps prevent serious complications resulting from influenza infection.
Medical officials agree that one of the characteristic features of the influenza is its air-borne infectivity. "One case to-day may mean a hundred to-morrow and thousands within a week," according to the chief medical officer of the Local Government Board. To protect oneself against the infectious illness that can spread without direct contact with the sick, it is recommended that people situate themselves in well-ventilated rooms. However, once you have contracted the disease, you are to quarantine yourself in an isolated home.5 Other symptoms of influenza include extreme exhaustion, aching limbs, headaches and sometimes, inflammation of nasal mucous membranes.6 The most common preventatives and curatives sold at the chemist's are quinine, cinnamon, and eucalyptus, with quinine being a favorite prescription by doctors.7 However, other medicines are also used against the influenza epidemic. The author of "Influenza: Its Cause and Treatment" is noted for stating that Formamint Tablets are the best source of infection prevention.
Currently, one cannot explore the news without coming across the topic of the swine flu, scientifically known as H1N1. Swine flu is a respiratory infection derived from the influenza virus. The virus contains genetic materials from human, swine, and avian flu viruses. It was first identified in spring 2009, and since then has spread rapidly across the globe. The infection’s spread has been verified as a global pandemic by the World Health Organization. As soon as the swine flu virus was isolated, scientists quickly developed a swine flu vaccine. Four vaccines have been approved by the FDA for the prevention of the swine flu. The vaccines will be ready for distribution in October 2009. Now the question is: To vaccinate, or not to vaccinate? Millions of people are now preparing to answer this question.
