Although I’ve only written a bit about the recent outbreak of influenza A H1N1 (swine flu), I’d encourage you to take a look at this post by Kent Newsome that discusses where to find reliable information on this topic. This post is particularly nice, because it gives concrete examples of some of the useful things this blogger has learned from these various sources. Granted, most of the sources he discusses are affiliated with ScienceBlogs, but that shouldn’t really be surprising, given that there has been so much quality blogging here recently on the topic of swine flu (particularly by Effect Measure and Aetiology).
On a mostly unrelated note, I’d also encourage you to check out the ScienceBlogs homepage right now for another example of things that ScienceBloggers do well: taking on pseudoscience. In this case, it’s the outrageous ongoing explosion of quackery at The Huffington Post.
Update: Reader Sofia has also pointed me toward Virology Blog, which appears to have a large amount of scientifically-oriented information on the topic as well.
