The Centers for Disease Control and Prevention (CDC) has created this uniformly excellent site to help the general public learn about the H1N1 flu. The homepage is well-organized, and it contains helpful social networking buttons, along with direct links to email updates, and their RSS feed. Here, visitors can also read the "Situation Update" section, which includes a map of the United States showing the weekly flu activity estimate maps and a number of other charts and tables. The site is chock-full of other helpful resources, including a section dedicated to "General Info" about the flu, information about vaccinations for individuals and public health officials, and a "What's New" area. The site is rounded out by a selection of podcasts and video clips.
