If this mutates, the world would not be prepared. There is not enough hospitals and medication for this. Especially since this is a NEW strain.
I'm speaking to a good friend in Mexico and he told me that it's a lot worse than the media is giving off. Hundreds are dead and thousands have been infected.
This will fizzle, though as the flu season is practically over, but it COULD come back and hit harder during the fall and winter like other deadly viruses have. Or it could continue to spread. Spain, France, New Zealand, Canada, and South America have cases, so time will tell.
