Swine flu is a virus infection which usually infects pigs and can be transmitted to humans as well. But, the swine flu virus that is of interest to us would be the novel swine flu H1N1 virus which came to be know by all of us as the ‘Pandemic A H1N1’ following the declaration by the WHO that it has reached the pandemic status.
The virus or else the strain of novel H1N1 swine flu virus was first detected in June 2009 in Mexico and by the time the researchers were able to predict or publish their findings, the virus seems to have spread all over the region and in to the rest of the continents as well. Therefore, by the end of 2009, swine flu was named as a pandemic and almost all countries were gearing themselves to take on the mass numbers of swine flu victims.
Although the numbers infected were high, luckily, the fatalities and other life threatening events were not as high as it was expected. But, even then, the influence it had on the day to day activities and the global economies including the tourism and traveling were enormous.
As the disease spread like wild fire, the most important aspect was to identify the ways of transmission and apply measures to hold such transmission from taking place.
When discussing the modes of spread, as with many other viruses, the novel swine flu virus is usually present in the droplets of an infected person and therefore if a healthy person gets in contact with these infected droplets, they can become ill. A virus can enter the body through the mucous membranes and therefore a person touching the eyes, nose and the mouth following having contaminated hands can develop the illness. It should be remembered that, if these droplets lands on the surface of most of the objects in the vicinity, they have the potential to harbor the virus for some time and transfer the virus to a healthy individual who might touch these surfaces.
If not touching, the disease can spread through droplets, which can directly get into the oral or the nasal cavities through inhalation of airborne particles. Thus, if a healthy individual stays close to a infected person and if that person coughs, sneezes or else even talks directly in to your face, there is a possibility of these particles from entering the body and thus to develop the illness.
Apart from these, obviously, a person who involves in direct contact with an infected person such as by kissing and hugging can also acquire this disease.
