The new Swine H1N1 Virus is a mixture of bird, swine and human viruses merged inside the pig's respiratory system creating a strong fatal virus with an almost impossible cure.
The pandemic started showing in Mexico, then reported in US, then in New Zealand, and now in Canada. It's obviously spreading fast before the cure is found killing almost 150 infected in the world (WHO) since 24th of April 2009.
This is not an average Influenza, we were scared to the bones when we heard about the Mad Cow Disease and then about the Bird Flu, well, this is so far the scariest one. Originally Swine Flu only infects pigs, but unfortunately the one that has evolved now is able to pass the infection from pigs and humans and from humans to humans.
