I'm concerned about it, yes.
There is no immediate threat like the media is playing it up to be, however it is a very potent strain of the flu. IF it mutates to a form than can transfer airbourne from human to human then we're screwed to put it frankly.
There is a great possibility that this will NOT happen, but if it does, we have no vaccine against it and no way to stop it besides letting it run its course....it's about time to have another pandemic though, the world's got too many people.
