If you been listening to the radio, watched TV, or read any news source recently you have been hearing them rant about the possibility of a pandemic flu (or avian influenza). The idea of a pandemic flu sounds like the plot of a modern movie or book.
To help keep everyone inform the government has created the following web site PandemicFlu.gov to address this subject. This site calls itself the "The official U.S. government Web site for information on pandemic flu and avian influenza".
The site is broken down into several sections: General Information, Health & Safety, Monitoring Outbreaks, Planning & Response Activities, Travel & Transportation, and Research Activities. Then each section is broken down into sub-sections.
This site has a lot of great information, so check it out.
