Go directly to "Swine Flu and travel to Europe" link that is now on the Home Page. There are links to lots of good articles. I think this should be the first place anyone goes on this site for info about swine flu.
You should also check out www.cdc.gov and click on the H1N1 information. CDC is the official source for all US related flu information.
The term is now "H1N1 Influenza" as opposed to "Swine Flu". Some groups find the term "Swine" to be offensive due to their cultural beliefs.
Just thought I'd mention that since we are all savvy travellers and don't want to offend anyone while abroad.
