Recently birds began dying of a disease nicknamed "bird flu". A lot of people began to worry that it could turn into a worldwide epidemic, or Pandemic.
However, a lot of things have to take place before that can happen.
First, a new influenza virus subtype has to appear - one for which there is no human immunity. It must also infect humans and cause sickness. And it must spread easily and without interruption among humans.
One Asian and European version of avian flu meets the first two conditions.
But the third condition has not been met so, at this time a pandemic of bird flu does not seem likely in the near future.
