Following Sunday’s spike in conversations surrounding the swine flu outbreak, web chatter doubled on Monday, April 27. Nearly four percent of blogs, micro-blogs such as Twitter, web news and forums were related to “swine flu.” Already, by start of business on Tuesday in the U.S., the number had swelled to nearly six percent.

When looking just at blogs via BlogPulse, compared with any recent health crisis or pop culture meme, the swine flu blog conversations are now more than 10 times those surrounding the salmonella scare earlier this year, and nearly five times the buzz generated by singer Susan Boyle.
