resolve it without delay to preclude compromise of patient’s care and wellbeing. But this is not always an easy fix as in the case study of nurse PT and her ethical dilemma during the H1N1 pandemic in Ontario (CNA, August 2008) Ontarians had one thing on their minds back in April 2009....the influenza A virus subtype H1N1, or swine flu. On June 11, 2009, the World Health Organization (WHO) affirmed a global pandemic, with over 8000 confirmed cases in Ontario alone, and 95 confirmed deaths by November
Influenza viruses are constantly evolving due to the mechanism of antigenic drift. This results in seasonal vaccination to target only specific strains, which puts us in a race against the clock in the prevention of the next pandemic. One key to solving this is the development of a universal influenza vaccine, which would elicit a broad antibody response. This would target either multiple strains or strains from the past, present, and future in a single vaccination. As vaccine may target sites such
Influenza is an acute respiratory illness caused by infection of influenza A and B viruses. The disease can affect both the upper and lower respiratory tract and is often followed by systemic signs and symptoms, such as: sudden onset of fever, chills, non-productive cough, myalgias (muscle pain), headache, nasal congestion, sore throat, and fatigue. (Cox et al.1998). Influenza viruses evolve continuously, challenging mammalian and avian hosts with new variants and causing complex epidemic patterns
The influenza vaccine, also known as flu shot, is an annual vaccination using a vaccine that is specific for a given year to protect against the highly variable influenza virus. Each seasonal influenza vaccine contains antigens representing three or four influenza virus strains: one influenza type A subtype H1N1 virus strain, one influenza type A subtype H3N2 virus strain, and either one or two influenza type B virus strains. Influenza vaccines may be administered as an injection or as a nasal
Introduction/Background/History: Influenza better known as “The Flu” strikes the world every year infecting millions of people throughout different countries. Influenza is a deadly virus is an extremely contagious respiratory illness caused by the influenza viruses. Flu appears most frequently in winter and early spring. The influenza virus attacks the body by spreading through the upper or lower respiratory tract. There have been documented traces of the flu as early as the 12th century. The
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
approximately 50 million deaths were a detriment of the Spanish H1N1 virus pandemic; a respiratory virus. According to the World Health Organization, the second Influenza A H1N1 pandemic in 2009 spread to more than 200 countries causing more than 18 000 deaths. Before the World Health Organization had announced the official end of the pandemic in August 2010, in July 2009 the World Health Organization sent out a phase 6 warning that H1N1 could soon be a global pandemic. It is important to recognize
Influenza is defined as an acute, commonly epidemic disease, occurring in several forms, caused by numerous rapidly mutating viral strains and characterized by respiratory symptoms and general prostration. Spanish flu was more than just a normal epidemic, it was a pandemic. Epidemics affect many people at the same time in areas where the disease doesn’t normally occur. A pandemic is an epidemic on a national, international, or global scale. The Spanish flu was different from the seasonal flu
Influenza is a very serious disease that can lead to hospitalization and even fatalities. There are many different strands, infecting people of all ages and originating from different animals, which can be extremely fatal if the right care isn’t provided. Care for flu patients have changes tremendously over the years from once having no vaccine to having a limited amount of vaccines, only for the most prone individuals, to now having yearly vaccines to prevent the most common cases of flu. Doctors
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. At no time was a search for the cure for influenza more frantic than after the devastating effects of the pandemic of 1918. The pandemic killed somewhere between twenty and a hundred million
purpose? According to Wikipedia, The influenza vaccination is an annual vaccination using a vaccine specific for a given year to protect against the highly variable influenza virus. Each influenza vaccine contains antigens representing three (trivalent vaccine) or four (quadrivalent vaccine) influenza virus strains: one influenza type A subtype H1N1 virus strain, one influenza type A subtype H3N2 virus strain, and either one or two influenza type B virus strains. Influenza vaccines may be given as an intramuscular
