Most of what you need to know about the current swine flu situation can be found on two websites. The Centers for Disease Control manages this site, which has all the latest news, information about the disease's symptoms and prevention, and links to other sources. The Department of Health and Human Services manages this site, also packed full of useful information (including historical information on flu epidemics).
Both sites have RSS feeds linked on their sites, and you can find their Twitter feeds under BirdFluGov (despite the account name, it does include swine flu information) and CDCemergency.
For the latest news stories, another Twitter feed is the San Jose Mercury News, which maintains a feed specifically for swine flu stories. (For a general news feed with plenty of flu updates, I use Breaking News.)
You may be interested in the swine flu outbreak map, a Google Maps mashup. This purports to show every known instance of swine flu around the world (of the current outbreak). The map also provides information on the current state of the ill person.
Even for those who don't live in New York, the New York State Department of Health has a very informative site on swine flu. And finally, you might want to keep an eye on the Indiana Department of Health's website.
