We've got a BAD bug - the ER doc said it's most certainly noro. It's lasting about a week from first sickness to 100% better. My four year old has been the worst, he's been v* on and off since Saturday night, so five full days now, and he's still puny on the couch. It's been really rough, on Sunday before we went to the ER he had v* 30 or more times that day. The adults who have picked it up have had a very mild go of it - nausea, stomach cramping, and d*, but no v*.
