As said and debated, the new flu strain is quite similar to most strains of the famed flu virus that is spread from person to person right after it jumps species from the zero host animal, first we had avian flu then swine, both of which jumped the species barrier which normally prevented cross species jumps. This trait of the new strains alarmed scientists for never in history has such cases occurred in modern times.
The Avian Flu is almost on the treatable stage but with the coming of the new strain, a more general vaccine may be needed to handle all of the flu strains, for the new strain is a combination of H5N1, H1N1 and the human flu virus which has the ability to mutate. Another alarming trait of the virus is that a case of reverse infection has already been found in New Zealand, a case of a human host getting a swine sick with the flu. The cross contamination of the virus is the bad thing. Flu can be weathered out with proper treatment and monitoring but for a strain that can come and go as it pleases, it truly is an alarming development.
