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).
The H1N1 virus, just like seasonal influenza, is simply spread by the minute drops in a sneeze or cough. The person infected may cough into an empty space but it will leave microorganisms (germs) on the place that can easily be picked by the other person by touching that place.
The major symptoms of swine influenza are reported to include chills, dyspnea, headache, vomiting, diarrhea, myalgia, and fatigue. The chances of having Conjunctivitis is uncommon, but has been reported in some cases. Other symptoms include mild illness of respiratory track like nasal blocking and rhino rhea without temperature. In very rare cases sporadic severe diseases like pneumonia and respiratory failure also has been reported. Approximately thirty to fifty percent of the severe and deadly swine flu infections have been among young and middle-aged people who were previously in good physical shape (Barnes, 2008).
History of Swine flu
The Influenza outbreak of 1918, also remembered as the “Spanish” flu strain, and graded as an epidemic, is believed to have infected more than thirty percent of the total population of the world and became the source of as many as fifty million fatalities (Barnes, 2008). The death figure, according to the United States Center for Disease Control, could have been almost twice that since a number of people departed their life in that era were not actually diagnosed, nor were any samples of blood taken for testing and identification of the infection in the laboratory.
The rising rate of the swine flu infection rate has forced WHO to...
