Influenza

Influenza is a highly contagious disease which can spread across the population by the body secretions which contain the active influenza virus (Collignon & Carnie, 2006). It poses serious threats to the society as it promotes fear, anxiety, and discrimination, and consequently causes destruction to the normal function of the society (Selgelid, 2009). Unless people develop immunity against the influenza virus (Collignon & Carnie, 2006), an influenza pandemic will remain a global emergency as extremely

From 1918-1919, the influenza virus swept the world and had disastrous effects. Different factor contributed to the spread of the virus. Many religious groups believed the virus was an evil that had fallen on the land and that only God can save them. Others caught the disease due to the lack of sanitary prevention, such as there being no inspections in the trading ports. Also many people were ignorant and knowledgeable about the pandemic because of the lack of response from health/government officials

favours the spread of the virus. Highest incidence of influenza infection is seen in young population which may be due to lack of exposure to different strains. Children are mainly affected during epidemics (Rao, 2003). The influenza virus triggers pulmonary inflammation resulting in infiltration of inflammatory cells and an immune response. The primary target and the principal host for the virus are Bronchial epithelial cells. Generally influenza viruses are recognized and destroyed by innate immune

Barry’s passage of “The Great Influenza,” where he writes an account about the 1918 flu epidemic that struck the world. In his account, he goes into further explanation about the rigors and fulfillment of being a scientist, and simultaneously, discusses the tedious process of their research. Ultimately, society is educated that the life of a scientist should not be absolute, but it should consist of persistence and courage. In John M. Barry’s “The Great Influenza,” the author employs innovative

A man named Osler suffered from the influenza for about 3 months. His most recent biographer believes he could have lived if he was under the care of Johns Hopkins Hospital. They might have saved him. On September 20, 1919 many of the best scientists gathered up. They had to be prepared. It was epidemic and was rapidly spreading. In just eight weeks in early 1920, there were 11,000 deaths that occurred in New York and Chicago. A man named John Dill Robertson who had been deeply concerned about this

November 17, 2015 MCB4403 Emerging Infectious Diseases: Influenza Influenza, or what most people call the “flu”, is a respiratory infection that is an example of an acute emerging infectious disease. Influenza is caused by the influenza virus, which is a negative sense single stranded RNA virus and is a localized infection affecting the respiratory tract. Influenza virus has eight different RNAs in its genome that encode for viral genes. Influenza is prevalent throughout the United States and the world

Also by touching something with this said influenza virus such as shaking hands with someone who has the flu and then touching or holding your mouth, nose or eyes. Viruses like the influenza can live for 2 hours or even longer on surfaces like tables, handles, and chairs. This Influenza viruses can also be aerosolized, that is transformed into very fine droplets and is transported over more long distances. Thus these droplets usually can only affect direct transmission or the person-to-person transmission

activated to level 2. April 23, 2009: The National Microbiology Laboratory confirms H1N1 influenza in Mexican specimens. The HPEOC is activated to level 3. April 25, 2009: Director General of the World Health Organization declares the outbreak “a public health emergency of international concern”. April 26, 2009: The Agency confirms the first case

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. (1)Physical barriers help keep the hazardous organisms and materials outside the body. Skin is the largest body organ it provides both a physical and a chemical barrier against the outside world. The skin forms a protective layer that completely wraps around the body, shielding blood vessels, nerves, muscles, organs, and

Influenza Virus I think many can testify to being guilty of brushing off symptoms like a stuffy nose, and the feeling of fatigue as the common cold, treatable by over the counter drugs. We tend to ignore these minor signs of what could possibly be a very dangerous and severe viral infection, this respiratory infection being the influenza virus. Flu activity most often appears between the months of February and May, leading many to believe their symptoms might be caused by allergies. Although symptoms
