This is an excellent ESL discussion lesson plan that covers the swine flu.  It contains a pdf, word, and mp3 for the audio.  There are ESL activities that go over the vocabulary such as vaccine, so far, toll, reported, away, could, severe, outbreak, pandemic, and other vocabulary associated with the news event.  It also includes a pre and post task for the reading or listening and discussion questions for students to go over after the activity.  There is even a writing activity for the lesson plan as well.  This is another great lesson plan by Sean Banville from BreakNewsEnglish.com
