Here are more additions to The Best Sites For Learning About The Swine Flu Outbreak:
Containment Efforts is a slideshow from The Wall Street Journal.
The BBC has a good and regularly updated map of the outbreak (thanks to The English Blog for the tip).
The CBBC Newsround has added quite a few very accessible materials on the swine flu. You can see a commercial/public service announcement about the flu that is being played in the UK at the same site.
