It does look like we have a pandemic on our hands, in that it has spread to Texas, Kansas, New York (possibly) and New Zealand. An epidemic only means that there are significantly more cases than predicted, and pandemic means that it is an epidemic on a global scale. The best evidence shows that there isn't a high mortality associated with this flu with good medical care, so I won't be losing sleep over this. In fact, the terms epidemic and pandemic are often misused, sometimes intentionally, because of the emotional response and call to action that they trigger. For example, we no longer have an AIDS epidemic, as the rate of infection has become stable. It is still a major public health concern, but is now in an endemic phase.
