I have blogged about this in the past, but a great way to keep current is to set up a Google News Alert–I came across a reminder of this on http://mashable.com/2009/04/25/track-swine-flu/ which had a great page on tracking Swine Flu:
One of the best ways to keep up-to-date on recent changes or
breaking news is to use Google News and Google Alerts to have breaking
news emailed to you or sent to your RSS reader. Set up a Google News Alert with the keywords “swine flu” to be sure you catch any major mention of the issue.
