Swine flu is one of those emerging infections that are constantly hunting a majority of human beings. It is basically H1N1 Flu or Swine Flu. Swine flu is the disease of pigs that does not normally affect human beings however there is no compulsion. Nowadays, people are diagnosed with swine flu that is caused by a virus. The symptoms of swine flu are not different from common flu, but it may include body aches, fatigue, chills, cough and headaches.
The Risk Factors of Swine Flu
The swine flu is contagious and can transfer from the affected person to his or her acquaintance. There is no vaccine discovered yet however it is possible to avoid the spread of swine flu from person to person. To treat or to prevent swine flu antiviral medicines are available but the best way is self-precaution. The germs and virus that thrust you to respirator illness, that is influenza, must be prevented. Following ways will be helpful in avoiding the risk:
- One must cover his or her nose and mouth while coughing or sneezing. A tissue paper or handkerchief can be used for the purpose. One must dispose of the tissue paper or cloth right after usage.
- Washing and cleaning hands after sneezing and coughing can contribute a lot in saving others from getting the infection. It is suggested that alcohol based hand cleaners must be used to wash.
- If one goes on touching or rubbing one’s face especially mouth, nose or eyes, the germs will transfer to hands and thereby move to other people. It is best to keep your hands away from your mouth.
- If someone in your family, friends or acquaintance is suffering form the swine flu avoid to come in contact. In case you come in contact with the patient wash the suspected area thoroughly.
- In case one has swine flu the best way to limit the infection is to avoid school or office as much as possible.
There are three types of influenza A virus subtypes (H1N1, H3N2 and H1N2) that are circulating worldwide. Before 1998, swine population of United States was widely diagnosed with H1N1. However, the H3N2 subtypes are isolated from the pigs after August 1998.
Swine flu is among one of the great problem human beings are facing since recent decades. Inconsistent response is offered by the evolution of virus to the conventional vaccines. The standard swine flu vaccines that are commercially available are only effective in limiting the virus infection when the strain of virus is similar to important cross protection, where custom vaccines that make use of certain isolated viruses are used only in complicated cases.
To control the SIV and the prevention of swine influenza in farms the present vaccine strategies involve the use of a number of bivalent SIV vaccines that are provided on commercial level in United States.
Treatment of Swine Flue
For the prevention of swine flu and its treatment CDC recommends the usage of Relenza (zanamivir) or Tamiflu (oseltamivir). For a person who is sick, the use of antiviral drugs will help him feeling relieved by milding the illness. The antiviral can also help in avoiding serious complications. Treatment can be more effective if the vaccine is provided soon after the diagnosis of symptoms that is within 2 days of symptoms.
Swine Flu Outbreaks in Humans
As a zoonosis in human beings the swine flu is at numerous times reported in the history of mankind. In 1918, flu pandemic in human beings was attributed to the H1N1 that reflected only two probabilities: either zoonosis moved from swine to the humans or from humans to the swine. The available evidence of that time are not sufficient to propose healthy answer to the question.
The United States an army recruit at Fort Dix started to feel tired and sick, in 1976. The soldier dies the very next day where four of his colleagues were hospitalized. After the 2 weeks of his deaths, doctors pronounce swine flu to be the cause of his death and associated the strain of flu to the 1918 flu pandemic.
The latest strains of swine flu 2009 involve the re-assortment of few strains of influenza A subtype of virus H1N1. The prime genetic characteristics of these swine flu virus was also detected in the United States pigs in 1999. The source of this swine outbreak is unknown and there are a number of theories pointing out one factor or another. Some people believe that Asian and European strains migrated to the Mexico by the virtue of people or birds and combined with the strains of North America in the pig factory farms of Mexico before moving to the farm workers.
Efforts are made to curb the influenza but currently it seems impossible to deal with an issue of unknown roots. The best way to avoid death by swine flu is proper care and vaccine before getting the infection. Research is going on in the field of vaccines and the solution will be hopefully available in the early years of next decade.
