But Dr. Marc Siegel, an associate professor of medicine at New York University and author of "False Alarm: The Truth About the Epidemic of Fear," says it's way too early for panic.
He tells The Early Show co-anchor Julie Chen experts simply don't know how likely it is that bird flu will mutate into a form that can be transmitted from human-to-human, rather than the bird-to-human transmission suspected in the 65 human bird flu deaths reported so far around the globe.
"Keep in mind," he points out, "that this virus has been around since 1997, and it has increased in the bird population. But the key is controlling it in the bird population.
"The chances are that some virus will mutate so that it can go human-to-human, but it may not be this one. It only happens about three times per century that a real killer virus occurs, so we may be getting alarmed way too prematurely here. …It's something we should cool down about right now."
Not only that, but, "We already have a vaccine for it. It's being tested now in elderly people and looks very effective.
"But what we need to do is upgrade our ability to create vaccines quickly. Currently, we're using a chicken-egg medium to make vaccines, and we need genetic engineering. We have the ability, but it's expensive. I think, rather than stockpiling vaccines, we ought to focus on our ability to make vaccines quickly."
In addition, "People need to know that they should not worry about this because, again, if millions of birds have it, occasionally a human will get it who has close contact or repeated exposure to birds.
"There's no problem traveling to Asia, or with casual contact. You cannot get it from eating a chicken at all. It's from repeated, repeated exposure to birds that they could get it.
If anything, Siegel stresses, we shouldn't take our attention off the regular flu, which puts more than 100,000 people in hospitals each year.
And, "We should be concerned about knowing that our government is upgrading our vaccine policy, that we're look at potential epidemics that can occur. We need to gear up for potential epidemics, knowing it may not be this one that's gonna be the epidemic."
As for all the media attention bird flu is getting, Siegel calls it both good and bad: "It's a good thing because it puts attention on public health needs. It's a bad thing if it makes people think it will happen to them. Something only affecting birds and in Asia is not a risk to us in the United States right now."
