Are there fears that bird flu might mutate?

For sure: This is an ongoing, legitimate concern. All that is required for a major pandemic is for an existing influenza strain to mutate to something our immune systems can't respond to. If this occurs, the public health outcome could be devastating. We now recommend influenza vaccination for all people. Wash your hands, listen to the news, and make sure you have a medical home if you become ill.

Yes: Influenza is always changing its genetic material which is why you need a new flu vaccine every year. There are two types of change 1) drift which is a small change from year to year and 2) shift whichis a completely new change. Shift can lead to pandemics because there is a lack of immunity to the new virus in the community.

Yes: But not a problem yet let us not to worry too much.
