Avian Influenza The Avian Influenza virus also known as Bird flu is a disease that infects birds such as, chickens, turkeys, ducks, and geese. Symptoms of the infection are respiratory disease, unable to produce eggs, and fatality. Usually the symptoms are unnoticeable. There are two main types of Asian Influenza is LPAI and HPAI. LPAI is low pathogenicity meaning birds are not as likely to die from the virus. HPAI H5 is highly pathogenic, more severe and has a higher mortality rate. Outbreaks of this disease started in Europe and Asian. In 2015 there has been reports that AI has infected poultry in the United States. The United States is doing everything it can to keep this virus from rapidly spreading. The virus has been identified
The Great Influenza is a book not many enjoy. However, Dr. Petri enjoys this book for reasons that are lost to many. The book starts off on part one chapter 1 the Warriors. it starts off with imagery of September 12, 1876 talking about it crowd in an auditorium in Baltimore’s Academy of music. this was too launch John Hopkins University where they say they would change all of American education and in this first page you meet Thomas H. Huxley an English scientist who is the keynote speaker of this event. then give me George Armstrong Custer who “led the seventh Cavalry to with the stretching at the hands of him video savages resisting encroachment of the white man.” customer had spoke on the front page of the Washington star. then the book starts going deeper into detail
In his nonfiction text, The Great Influenza, John M. Barry explains that scientific research is an uncertain process. Barry supports this explanation by using rhetorical strategies such as repetition and a metaphor. Barry’s purpose is to prove scientific research is a confident process that allows one to be courageous on the side of uncertainty. Barry uses formal tone with his audience that goes beyond researchers.
Viral cell culturing has become a commonly used method for the cultivation of viruses. Before cell cultures, many viruses were propagated by the use of an embryonated egg. However, today embryonated eggs are still used for the production of vaccines and for the isolation of avian and influenza viruses. In addition, there are several procedures that must be carried out when a virus is grown in an embryonated egg. For instance, the eggs must be candled (to determine viability) and disinfected before a hole is drilled. Next, the virus must be injected into the appropriate area of a 5-14 day old embryonated egg. Signs of successful viral growth include pocks, hemagglutination, or death of the embryo 2-5 days after injection. In this lab, the purpose was to inject Influenza A Virus (H1N1) strain APR/8/34 into the chorioallantoic sac of a 9-11 day old embryonated egg. Our hypothesis was that the Influenza A virus will grow successfully in the embryonated egg to yield successful results for the following lab.
Annually there are a number of children who contract the influenza during the influenza season that results in an increase in costs in pediatric office visits and antibiotic and other medications consumption and also in a significant increase in absences from school and work. Thus influenza vaccination of children can help reduce the number of visit to pediatric office, hospitalizations, and help prevent the spread of influenza in the wider community. Moreover vaccinating children is cost effective when considering all the cost of treatment for influenza and its complications. Therefore yearly vaccination of children with the inactivated influenza vaccine save parent money and time away from the pediatric clinic. Influenza vaccine does not
Once there was a virus named Birdie. This virus was a Bird Flu, or Avian Influenza, virus of the subtype H5N1, the first strain of Avian Influenza having the ability to infect humans (Normandin and Solan). Birdie looked like a microscopic pomander, a fragrant orange with cloves stuck in it. Inside, she had eight pieces of single stranded ribonucleic acid or ssRNA. Birdie was deadly to humans, but was not able to spread from one human to another. She could only spread from birds to humans ("Bird Flu"). Birdie started out inside a chicken named Cluck, where she was formed. A little while later, Cluck's farmer Mark, sold his Cluck, to Joe, another poultry farmer because Mark did not realize that Cluck had H5N1. After a few months of Cluck living
According to the CDC there was a breakout in “1918-19 Flu pandemic, which killed as many as 50 million people worldwide”causing the biggest breakout for Influenza (Reconstruction of 1918 Influenza Pandemic Virus). Influenza originated from Asia and the Middle East. Virtually all mammalian species have influenza. Influenza is a contagious respiratory illness caused by the Influenza virus. There are three types of Influenza: type A, type B, and type C. Influenza has numerous symptoms, vaccinations, and is unlikely to kill it’s host.
The first alternative, to such a policy includes immediate dismissal of any staff that refuse to comply regardless of being directed that it is a requirement (Brady, 2013). According to Brady et al. (2013), policies that dismiss staff who do not comply usually have higher rates of compliance. The second alternative, includes work restrictions for the unvaccinated workers during Influenza season and an overall increase in insurance premiums (Vaughan & Arsneault, 2014). This option would deter the spread of the virus in the infected to the uninfected because of the limited point of exposures to the source. The unvaccinated healthcare worker would therefore, be subjected to working fewer hours and face higher
Describe two innate (nonspecific) immune responses that might prevent an influenza virus from causing any noticeable infection, even if the virus enters your respiratory passages.
It is caused by various types of influenza viral strains. According to Marjorie, three types of influenza viruses are recognized: A, B and C. Type A is more common. Influenza virus belongs to the Orthomyxoviridae family, are enveloped, pleomorphic, and contain the genomes of 8 single-stranded negative-sense segments of RNA. Influenza viruses have three key structural proteins: hemagglutinin (HA), neuraminidase (NA) and Matrix 2 (M2). Both HA and NA are surface glycoproteins diverse enough that their serological recognition gives rise to the traditional classification into different subtypes.
The influence of influenza during 1918 took a huge toll on the people of the world. They struggled as the pandemic affected nearly all parts of the world, though the different societies dealt with the issue differently due to their cultures and beliefs. When looking at a disease an important factor that comes with curing it, comes looking at where the disease begins. As a disease slowly take out the population, science and the people look for the root cause of the disease in order to control and stop it in its tracks. The world commonly sees Asia or specifically East Asia as to where most diseases and pandemics can be linked to. Rather than just blaming a specific area for the disease developing, taking a look as to how their society deals
The 1918 influenza had a catastrophic impact on the world. It washed over the world in waves, killing millions from even the most remote places on every continent. No one was safe from this lethal disease. It also had an odd pattern in victims that nobody had seen before, killing strong and healthy people. It was a ruthless disease that devastated it’s victims and killed them in a macabre way.
The Spanish influenza, also known as La Grippe, Spanish Lady, three day fever, purulent bronchitis, sand-fly fever and Blitz Katarrh (The 1918 Influenza Pandemic) was a global disaster which occurred between March of 1918 and the spring season of 1919 (The 1918 Influenza Pandemic). This virus was more catastrophic even than the First World War which was occurring at the same time the influenza broke out, killing more people than the Great War itself (The 1918 Influenza Pandemic). The virus killed more people in one year than in the four years of the Black Death Bubonic Plague (The 1918 Influenza Pandemic). Many questions about the flu’s origin and its nature remain largely mysterious to epidemiologists and scientists alike. (1918 Influenza:
The influenza virus is “an acute respiratory tract illness, with outbreaks occuring annually that are responsible for large numbers of hospitalization and death worldwide” (Dool et al. 314-319). The influenza virus has a few common symptoms that
Wild aquatic fowl, ducks in particular, serve as a reservoir for the Influenza virus to transmit into poultry and then to humans. Infected birds shed flu viruses in their saliva, nasal secretions, and feces (CDC, 2004). The current virus seen in Asia is denoted as H5N1 and was first seen in terns in South Africa in 1961 (CDC, 2004). The first human seen infection of the avian H5N1 viruses was in 1997 in Hong Kong in a three- year old boy (Ruben, 2005). The outbreak involved 18 cases and killed 6, one third of the confirmed infected population (Rueben, 2005). In three days 1.5 million birds were killed in order to prevent further spread. A new pandemic is now on the horizon with recent outbreaks in poultry in the eight Asian countries of Cambodia, China, Indonesia, Japan, Laos, South Korea, Thailand, and Vietnam since 2004 (CDC, 2005). As of July 5, 2005, there have been 108 reported human cases of the H5N1 virus with 54 deaths (CDC, 2004). In wake of a
What is influenza surveillance? It related to influenza like illness and severe acute respiratory infections. For your information, influenza surveillance has its owned global standards. This have been provided by the WHO’s Global Influenza Programme (GIP). What GIP can do actually? They analyzes and collects the data. The data is about the virological and epidemiological of influenza surveillance. It has been collects and analyzes from around the world. The quality of influenza surveillance need to be share and monitor oftenly.
