Influenza Viruses Are Responsible For An Average Of The Deaths Per Year Globally

For long before the 1918 pandemic, doctors had been trying to isolate the microorganism that causes influenza. In 1892, one man, Dr. Friedrich Johann Pfeiffer, believed he had the answer. His discovery, Pfeiffer’s

Every year, millions of people start talking about the influenza virus and getting their vaccines as the flu season approaches, which starts around the October-November period and reaches its peak between December and March. Therefore, public health officials around the world- and in the U.S in particular- are constantly challenged by properly preparing for the annual influenza dilemma, given that this viruses, and other respiratory viruses, are a serious health threat to the U.S population and the world as a whole. Furthermore, what makes the influenza virus even more challenging to control is that it can mutate rapidly and reassort to form new strains, having the ability to reside in multiple animal hosts. In fact, many scientists and researchers have been doing in-depth intensive research so as to understand the mechanism behind this unique characteristic of the virus, try to find new ways to control it, and explore different areas of protection and vaccination.

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

Although the majority of people infected with influenza recover completely within a week to ten days, some people are at a greater risk of experiencing more severe and long-lasting complications. The flu can lead to complications such as pneumonia and in some circumstances, severe complications in high-risk groups can lead to death. The number of deaths attributed to influenza varies each year, but it is estimated to be approximately 500 to 1500 deaths per influenza season. People who are at an increased risk for complications include very young children, people over 65 years of age, and those already suffering from medical conditions including bronchitis, heart disease, diabetes, and kidney disease. Influenza vaccinations administered to high-risk people reduce hospitalizations, premature deaths, and they result in substantial cost savings to the health care system.

According to the Centers for Disease Control and Prevention, “It's estimated that 90 percent of seasonal flu-related deaths and more than 60 percent of seasonal flu-related hospitalizations in the United States each year occur in people 65 years and older “ (2011).The CDC advises that the best way to prevent and control the spread of influenza each year is by the use of vaccinnations. In effort to control and prevent influenza epidemics, the CDC uses the epidemiological process to predict the strain of the virus that will be most relevant to the population and this data is used to formulate influenza vaccinations (Centers for Disease Control and Prevention, 2011).

Each year 6-20% of U.S. residents are infected by influenza and more than 200,000 people are hospitalized due to complications (Klepser, Corn, Schmidt, Dering-Anderson, & Klepser, 2015). Influenza has a huge impact on not only the health of our nation, but economically, as well. Studies show that the single most effective way to prevent the spread of influenza is to vaccinate. The CDC recommends that all children over 6 months old to be vaccinated against influenza yearly (CDC, n.d.). Seldom have there been medical advancements that have impacted the health of billions of people. One such important medical advancement is the invention of vaccines. At the end of the 20th century, the CDC published its list of

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 last few days of summer are upon us, the leaves are beginning to change and it is once again fall in East Tennessee. While many are beginning to enjoy a relaxing break before the stresses of winter and the holidays, healthcare providers are bracing for the rush. The rush I speak of is that of doctor’s offices which are over run with those complaining of fevers, aches, and chills. Influenza season begins as early as August and can run as long as in to late March. Those affected by the virus can range from infants to the elderly, but most complications occur in those over 65, including death. According to the World Health Organization, the number of elderly persons is expected to increase from 600 million currently to over 2 billion worldwide by 2050. (WHO, 2015) Due to the rapid increase of this age group in the upcoming years, the need to prevent and establish treatment for illnesses that have the potential to be fatal in this population is a top priority. Greater risks of mortality in those over 65 who contract influenza can be attributed to several factors including: the elderly’s decline in immunity response, the inability of the elderly’s body to fully recover from infection, and finally, the long term complications of influenza among those who are already compromised.

Influenza over the years has mutated so many different times that it is hard for scientists to keep up with new and updated versions of vaccines to keep people protected. The Flu for some people can cause major complications such as pneumonia and bronchitis because the Flu attacks the respiratory area, but most people who get the Flu will recover in a few days or up to a few weeks. The 1918 Spanish Flu was the worst epidemic that ever hit the world and the contributing factors of the millions of death were that there was no such thing as vaccines or antibiotics to fight off infections. The side effects were so severe that doctors misdiagnosed Influenza as a different infectious disease, and this specific Flu killed more people than the plague.

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.

Avian influenza is a disease that has been wreaking havoc on human populations since the 16th century. With the recent outbreak in 1997 of a new H5N1 avian flu subtype, the world has begun preparing for a pandemic by looking upon its past affects. In the 20th Century, the world witnessed three pandemics in the years of 1918, 1957, and 1968. In 1918 no vaccine, antibiotic, or clear recognition of the disease was known. Killing over 40 million in less than a year, the H1N1 strain ingrained a deep and lasting fear of the virus throughout the world. Though 1957 and 1968 brought on milder pandemics, they still killed an estimated 3 million people and presented a new

Each year in the United States, 3000–49,000 influenza associated deaths occur, with over 90% reported among older adults aged 65 years or older. Influenza also results in an estimated 226,000 hospitalizations, with hospitalization rates among older adults increasing over the past 2 decades (Nace et al., 2015). Influenza is a highly transmissible viral illness that may lead to severe complications from underlying diseases, primary viral or secondary bacterial pneumonia and death (NCBI, 2015). Immunization is one of the most powerful and cost effective interventions against

According to Healthy People 2020 a goal of theirs is to “increase immunization rates and reduce preventable infections.” The influenza virus is one of these preventable infections, which can cause serious harm to patients. The influenza virus is known as the “flu.” Everyone in his or her life has had some experience with the flu, whether that is himself or herself or a family member. What if there was a way to ensure people from contracting a strain of the influenza virus? Well, thanks to technology and medical research there is.

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

Background & Audience Relevance: Influenza is an infection that can affect anyone around the world. Am quite sure almost everyone, if not all of us, have been infected with influenza at some point in our lives.
