The swine flu virus has become one of the most used terms over the past few months. It is a new strain of virus that was detected in Mexico around springtime in 2009. Since then, it has spread throughout the world in small pockets, because of the number of international travellers that left Mexico around the same time. The scientific name of the virus is H1N1 virus and it is simply yet another form of the influenza virus that we all know as the common cold. Dubbed ‘swine flu’ because it originated from pigs, the swine flu virus has spread rapidly but is not quite as deadly as people are claiming it to be.
First of all, one must understand where swine flu comes from. It is a mutation of the virus that causes common cold. It started through pigs like the bird virus started from infected poultry. However, in this case swine flu will not spread through pigs. The outbreak of swine flu all over the globe has mostly been because of infected carriers seated aboard many international flights. Due to lack of proper screening procedures and adequate vaccinations against swine flu in the earlier stages of its detection, many of these carriers were able to pass it on to others. Thus, H1N1 became elevated to the stage of a pandemic, as declared by the United Nations and caused the subsequent panic. Since then, procedures for screening have been made far more stringent and its been found that effective treatment for swine flu.
As mentioned before, the origin of H1N1 is believed to be Mexico. However, genetic profiling on the virus has revealed similarities to almost all the viruses that have been commonly seen in parts of South America, Asia, Europe and varied islands in the Pacific Ocean. It has also been linked to the Spanish Flu but no concrete evidence has been found till now supporting this fact. As of now, all we know is that it is not fatal unless undetected for a very long time, much like the influenza virus.
Irrespective of where the swine flu came from, it has now been declared as a pandemic. It spreads much like the normal flu, through contact with the carrier. Coughing and sneezing can spread the virus if other people inhale the respiratory droplets. Any other form of physical mouth and nose contact with a carrier can transfer the virus to another. There have been many cases of death reported in different countries, bringing the over all toll up to 9,000. Even with the development of a cure, it continues to spread but has been slowed down to a considerable extent. With the help of the Tamiflu tablets and other forms of personal care, the spread of this virus can be slowed down.
