When swine flu epidemic broke in 2009 the controversy around this disease was amazingly high. Actually this was the second swine flu epidemic that managed to cause a real threat among people from all around the world. The first swine flu epidemic dates back to 1918. Well, when swine flu epidemic broke for the second time, many countries developed health programs to quicker overcome the disease. In April 2009, American researchers still did not know how contagious and serious the virus really was.
The proportions that swine flu epidemic had were determined by the fact that this is a highly contagious disease, easily transmitted from one person to another. While an impressive number of people were hospitalized due to swine flu, many others died due to this condition. Travelers were checked and medically tested before entering the borders of a new country, to reduce the risks of swine flu epidemic to become very serious and the potential spread of the condition to be decreased as much as possible. Although swine flu epidemic started as the condition easily spread from infected individuals to healthy ones, you should know that is not the only way you can contact the disease. Direct transmission of swine flu from pigs to humans also is possible, although this is not a very common thing.
The swine flu epidemic was over only in 2010, when the World Health Organization announced that no more cases of the disease have been diagnosed worldwide. Many vaccines were created for the swine flu prevention and more than 65 million people in over 16 counties were vaccinated. The vaccine was considered to be very efficient and quite safe in protecting individuals against swine flu. However, many people all around the world refused the vaccine, due to the potential side effects that could have been experienced after its administration. One death was confirmed in Canada, for instance, after the administration of the swine flu vaccine. Many other cases of bad reactions to the composite of the vaccine, made people avoid it. Luckily, the swine flu epidemic was overcame after all, although the risks of occurring once again have not been completely eliminated.
