Influenza Disease                                                                                                           Common and Scientific Name:                                     This is the Influenza Disease, which is                       also known as “The Flu”. It can be caused by                        the viruses Orthomyxoviridae Influenza Virus                              (A)(B)(C)(D).                                             Classification:The classification for Influenza is Virus, Orthomyxoviridae, Orthomyxovirus Influenza (A)(B)(C)(D)These orthomyxoviruses are usually spherical and are 80-120 nanometers diameter wise. These are usually six to eight segments of single-stranded RNA. Influenza viruses are organized into groups A, B, C, and D according to the variation in nucleoprotein antigen. Types A and B are usually the ones that cause new strains. Type C is antigenically stable.        Symptoms:Initial symptoms include fever (typically >100°F), fatigue, muscle aches, sore throat, headaches, chills, nasal congestion, diarrhea, and sweats.Advanced symptoms include cardiovascular system failure, respiratory system failure, kidney failure, and pneumonia these symptoms are uncommon and occur in the elderly.Mode of Transmission and Geographic Location:Influenza can be contacted due to close contact with infected individuals, influenza actually originated in Spain, but since then it has spread worldwide.Treatment:Some initial treatments are drinking plenty of fluids, rest, pain relievers (optional), antiviral medication such as Tamiflu or Relenza.There aren’t any long term treatments for Influenza specifically, but there are many long term treatments for its complications such as diuretic medication (cardiovascular system failure), getting a tracheostomy (respiratory system failure), or receiving a kidney transplant (kidney failure).Prognosis:It would take a week or two to recover from the flu. Approximately 40,000 people die from Influenza a year out of the 200,000 people who get it. The mortality rate of Influenza is <.1% when patients are treated, however if the patients remain untreated, the mortality rate can rise up to 2.5% (seasonal flu). The life expectancy for those infected with Influenza is still 79-81 just like every other person, but in some cases, Influenza A produces new and unique strains that trigger for pandemics or more fatal illnesses such as the bird flu or avian influenza. In scenarios like this, the mortality rate can rise up to 60%. (Death is more common among the elderly and infants.)Prevention:You could hinder the spread of Influenza by receiving your yearly flu shot, cleaning your hands, shielding your coughs and sneezes, distancing yourself from crowds, and keeping physical contact at a minimum.
