INFLUENZA Essay -- essays research papers fc

In influenzaenza, also known as the flu, is a virus that infects the respiratory tract. Although grippe is not as severe as many viral infections its almost the worst for viral infections of the respiratory tract. Typically, when someone is infected with flu they experience fever ( usually 100 to 103F in adults, but all the same higher in children) and causes a cough, sore throat, runny or snug nose, and also headaches, muscle aches, and usually extreme tiredness. in that respect are sometimes other symptoms such as nausea, vomiting and diarrhea but usually only in rare cases with young children. One other shade The term Stomach flu isnt really caused by the flu virus.The average recoery time from the flu is ab proscribed 1-2 weeks, although some patients do develop more than severe complications such as pneumonia, which are assailable of being life threatening. On average, influenza is associated with more than 20,000 deaths nationwide and more than 100,000 hospitalization s. These are usually from patients who develop complications and they are usually children or the elderly, although complications pot develop at any age.There are three references of influenza viruses, Groups A, B, and C. Only Groups A and B are responsible for causing the epidemics of flu that occur almost every category. flu C is different in several ways because it causes mild to no symptoms and doesnt cause the annually epidemics. Scientists put out most of their effort to harbor influenza A and B because of their huge impact on the nation and the world. influenza type A viruses have two proteins that determine their specific type. Take Influenza A(H1N1) the H stands for hemagglutinin and the N stands for neuraminidase. The current types of Influenza A are A(H1N1) and A(H3N2). Influenza A(H1N1), A(H3N2), and Influenza B strains are included in each years vaccinums.Influenza A viruses are very hard to control because they undergo mixtures, making it harder for humans immu ne systems to detect them. There are two types of heightens. The first is a series of mutations that occur over time and cause a gradual change in the virus. This is called antigenic drift. This process allows the virus to make a more stable change yet still evade the immune system. The second type of change is an abrupt change in the hemagglutinin and/or the neuraminidase proteins. This is called antigenic "shift. It isnt as s... ...uenza vaccines, since the vaccine is prepared from influenza grown in eggs. The most cat valium side effect is mild soreness at the injection site. weighty side effects such as such as spartan allergic reactions or Guilain-Barre syndrome are rare (fewer than 1to 2 cases per million vaccine recipients).Although the virus will continue to change and we will continue to chasten to defeat it, we never will. Just in the past three eld two new strains have been discovered but were isolated and wiped out quickly. Maybe next time we wont be so lucky but maybe we will. After all, its only the flu and humans didnt get this far by worrying more or less it.Works Cited (I did it in MLA Format so be happy)PReferencesInfluenza A(H5N1). Who.gov. Online.
