Introduction (.5 pages) Seasonal influenza commonly referred to as the “flu” is an acute viral infection caused by the influenza virus that can have possibly devastating effects on a community (“Influenza (Seasonal),” 2014). Seasonal influenza viruses cause annual epidemics that peak during the winter but can begin as early as late fall and last through early spring (“Prevention and Control of Influenza,” 2008). Influenza infections in the US affect a large amount of the US population. On average
obesity-associated changes in the course of influenza infection have not been established, although the relationship between obesity and influenza has been noted (Huttunen & Syrjänen, 2013). Human alveolar epithelial cells (AECs), as the first lines of lung defense, play important role in avoiding influenza infection in human. Researchers observed that compared to nonobese subjects, AECs from obese donors had higher rate of H1N1pdm09 infections, as the level of infection in nonobese and obese group were 26
ideal place to spread infection, because in one place you have lots of people with infection, lots of vulnerable people and lots of traffic between infected and vulnerable people. A nosocomial infection can be defined as a local or systemic condition resulting from an infectious agent that occurs during admission to a healthcare facility, but was not present on admission. Viruses are a significant cause of nosocomial infection, accounting for 5% of all nosocomial infections in healthcare facilities
Influenza and the Elderly 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
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
1 Executive summary Influenza viruses are zoonotic pathogens that constantly circulate and change animal hosts this includes birds, pigs, horses and humans. The possibility of emergence of new virulent strains that is able to cause human epidemic or pandemic is significantly high. Rapid development in this field continues at a rapid rate leading to constant updates on theory, techniques, and applications that are important for informing users of genetic information. This study aims to detect and characterise
Descriptive statistics was used in the research studies of the annotated bibliographies below and provides data that can be applied to the treatment of individuals possibly infected with the influenza virus. The data collected from specific populations shows the effects of specific antiviral drugs under certain conditions. Use of the data will enable healthcare providers to select the best course of action and determine proper use of limited resources in today’s cost constrained environment.
Influenza remains as a significant global threat to public health. In United States alone, a typical influenza epidemic results in over 25 million infections, 300,000 hospitalizations and 13,000 deaths every year (1). The virus evolves antigenically from one year to the next, requiring annual reformulation of the vaccine and leading to variable vaccine efficacy. Exacerbating this natural antigenic evolution, adaptation to the chicken eggs may occur during the manufacture of virus used to produce
INFLUENZA “Should we get vaccinated”? – Rough Draft I. Introduction a. Attention Getter: What are you willing to do or give up for the guarantee that you will never get down with flu? Pay a million bucks? Give up on ice-skating? Or give up on all the yummy cakes and ice creams? b. 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. c.
Therefore, Pizzola et al investigated the deposition, protection, and recall response of influenza virus-specific memory CD8+ T cells in the URT. These studies showed that influenza virus-specific Trm cells developed within the URT after intranasal influenza virus infection and rapidly cleared a secondary heterosubtypic influenza infection from the nasal mucosa and, in doing so, prevented virus spread into the lung. The URT is a key region to limiting viral spread
