It has been the past few weeks at my house. Started with my dd and ds #1 on one day, then 4 days later it hit ds #2. A few days after that I got it. Few days after that dh got it. Then my parents came to visit - within a few days, my dad got it. So far that's been the end of it, but it was a nasty bug. Fortunately it only lasts a day or two at the most.
