less than 1‚000 cases of avian influenza‚ or bird flu‚ in the US every year. Even though that number seems to be low‚ that does not mean that it is something we shouldn’t be concerned about. Many people do not know what avian influenza is‚ what the symptoms are‚ or if there is any treatment for the disease. Avian influenza can be defined as a highly contagious viral disease with up to 100 percent mortality in birds‚ and 60 percent mortality in humans. It is caused by influenza A virus subtypes

During the year of 1918 the movement of troops during WWI spread the Influenza disease. Influenza arrived in the United States at a perfect timing when there many new forms of transportation‚ media‚ consumption and warfare had expanded into public places where diseases could spread more easily. The new forms of transportation really impacted the U.S. and why so many people easily contracted the disease. I will analyze two letters written to friends by a doctor and nurse to show some of the conditions

The H1N1 virus (swine influenza) is a novel infection that has not earlier been known in North America. It has recently‚ however‚ infected a number of people in the United States and Mexico. Swine flu is actually a respiratory virus of pigs which was first identified in 1918 and although historic diffusion to human beings has been sporadic‚ the infection rate in humans is intensifying at present (Barnes‚ 2008).

Type A Influenza Virus Essay Influenza: a virus that replicates‚ mutates‚ spreads among species‚ and the cause of the recent H1N1 scare is definitely an apparent danger to humans today. Type A influenza is an RNA virus that ‘reproduces’ through replication. The virus particles are surrounded by hemagglutinin (HA) and neuraminidase (NA) – both are structural glycoproteins attached to the virus’s outside lipid bi-layer. HA serves its function in helping the virus to bind to the sialic acid receptors

Influenza infections are the leading cause of death. In 1918 Spanish flu killed so many people in the united state‚ and spread quickly like wild fire throughout the entire world. Many people died within the first few days after infection and others died of complications soon after. Nearly half of those who died were young‚ healthy adults.

New diseases and pandemics shock government and individuals‚ and are many times difficult to treat. This remained true in the past‚ whether it be the Black Death or the Influenza pandemic of 1918‚ and true today‚ as examined by governments and society trying to adjust to the new threats of Ebola and Zika. The 1918 influenza pandemic and the current response to Zika can be compared by examining how similar they are in terms of showing how government quarantines can be counter productive and how government
