Stomach bug. Apparently one's going around that causes a high-ish fever and tummyaches.
As yet, no yakkin' - but the day is young.
Doc said it's a 24-36 hour thing, so we should be clear by tomorrow afternoon at the latest (hopefully).
Of course, it doesn't help things a bit that I watched a Discover Health Channel show the other night about a horrible salmonella epidimic that made 200,000 people sick a couple years ago and caused some teenagers life-long damage...
