I've seen this kind of behavior in many forums, people saying that this swine flu is like the avian flu, this is nothing like the like of avian flu, let me do some basic explaining, the flu virus is called Influenza virus, this virus has a wide variety of sub-species, some affect humans, some aquatic birds, others horses, the problem is that swines can get infected with lots of sub-species of Influenza, now this is what scientists all over the world were afraid that would happen with avian flu, that a swine would get infected with both the human and the avian flu thus creating a new hybrid that would be able to do a lot of harm as the avian flu and spread between humans by air, and this is what has just happened in some sort of degree.
