The bird flu is kind of a tricky situation, that they're blowing some parts out of proportion on.
First, the virus is carried by birds, and cannot be transferred to huans readily. Secondly, and most importantly, it can not transfer human to human right now.
Now, there is a chance that it could mutate to a human to human virus, which would be horrible....BUT if this happens, you also need it to mutate into a virus that can be spread airbourne from human to human in order for any panic.
Okay, so assuming it mutates into a form that is transfered via air - from human to human - you will have a catastrophe on your hands, and potentially millions upon millions dead.
It is nothing like the Katrina predictions, the estimates are low if anything. Plagues have occurred in the world before, and they will again. A plague becomes a plague when the people are not able to properly treat the disease fast enough to stop the spread....which is exactly what will happen if the virus mutates to the point noted above.
This is the part that the media is blowing out of porportion: tamiflu (and other related treatments). Tamiflu *slightly* treats the strain of bird flu that is currently in animals. There is no evidence to suggest that it will have any effect on a strain that would affect humans...and there is no way to predict how the strain will mutate - thus NO way to create a vaccination. The media spends a lot of time telling us there's not enough vaccines for everyone...but they fail to include the part - the reason scientists and doctors predict massive death rates - that the vaccines we do have are most likely completely ineffective against a virus that would cause worry.
So esentially don't worry much. If the virus does mutate enough...there's probably a 1 in 10-20 or so chance that you'll die, and there's absolutely nothing you can do about it, now - or later.
