Swine Influenza or the H1N1 is loosely called as a respiratory debility that is stimulated by viruses and to be precise it is the influenza virus that causes it. The swine influenza was first diagnosed in the year 1930 in the United States that infected the respiratory tract of the pigs resulting in nasal secretions and a cough that sounded like a bark while the affected pig looses appetite. Due to close association of humans with pigs, the flu got its way into human body and was originally seen in Mexico in 2009. The flu comes into picture because the flu only infects humans and features two prime facet antigens the H1 which is hemagglutinin type 1 and N1 which is neuraminidase type1. Present day study has uncovered that the 8 RNA strands from the novel H1N1 have strands derived from flu, 2 from the avian or bird and 5 from the swine flu strands
But why is the H1N1 infecting humans?
Researchers are taking and considering two prime series of consequences to be the reasons why the H1N1 is becoming the main motive of influenza in human beings.
The first consideration is that the influenza toxins which are type A, B and C are enclosed RNA contagion with a genome. This means that the viral RNA ancestral cipher is not a solo filament of RNA rather it lives as 8 variations of RNA wedges in influenza virus. Human flu can taint a pig like the swine flu.
The second consideration is that pigs can disport a capacity in being the channel to host other new kinds of flu’s because the pig’s respiratory tract can be tainted straight with influenza from birds, mamals and humans. Pigs can get these viruses from the habitat and pass them to the mammalian population.Movie Rings (2017)
What are symptoms of H1N1?
Just like any other influenza the swine flu posses the same signs and symptoms. The infected person will experience
• Fever with body temperature reaching above 100F
• The person will have a nasal secretion and coughing
• Fatigue and headache are other signs
• The victim will end up in vomiting, diarrhea and feel nauseated
• After infection and like it was witnessed in Mexico the victim can develop pneumonia and develop severe respiratory problems.
Diagnosing H1N1 cases
The main diagnosing method is by monitoring the history of the victim with people suspected to have the flu and are also diagnosed and proven to have it. Usual a suspect will start feeling the above signs and symptom and to certify that, a simple quick nasopharyngeal swab is done to distinguish if the patient is having influenza virus A or B. The test can turn out negative meaning the person has no influenza viruses or positive for type A and B. If the test is positive for type B, the infection is not likely to be swine flu but if the test is positive for A the victim might be infected with H1N1 or a conventional flu strain.
Treatment for H1N1
The best treatment so far is by use of vaccination and recently many laboratories have come up with swine flu vaccines. The first vaccine which is a nasal spray vaccine was only approved to be used for healthy people and under the ages of 2-49 years.
There is also another vaccine made from killed H1N1 and can be administered to people of ages from 6 months to elderly including the expectant mothers. The vaccines are safe and effective.
