having only general knowledge, there is in reality, only so much you can do to protect yourself from the flu, or any variety of disease. Unless you are willing to live in a hermetically sealed bubble, away from all civilization, you are at risk for whatever appears on the horizon. And that is no guarantee you won't develop some life-threatening condition, even in the bubble. Sure we buy survival items and tell ourselves we are prepared for disaster, but very little is in our actual control. If you spend your life in worry about this epidemic and that pandemic, this war and that terror attack, this tornado or that hurricane, you might just have a heart attack from the fear of it all. Every man and every woman has a date with death at some point, no one has cheated it yet. I can't quote any stats, but many many thousands die each year in car crashes, far more than 9/11 too. From my understanding, there is no vaccine yet for bird flu, and it has not yet been transmitted to humans. Scientists are working on it and may find an answer, but worry won't make it happen any faster. Each day has enough trouble without worry about the next.
