2 of my 3 have had lab-confirmed cases. One was hospitalized for a week (note, though, that he is special needs with a very long list of underlying medical issues that complicated things) It was 8 days of non-stop vomiting and diarrhea, with the most foul smell I have ever smelled. It was pretty awful, I'm not going to lie. I just laid them on towels and kept a spray bottle of water because the diaper rash was horrible by the end of the first day alone. Besides, the diarrhea was so frequent, we would have spent a fortune in disposable diapers.
So yes, my kids got it, I expect my 3rd to get it at some point. It meant sick kid, no sleep, and lots of laundry, but it was no different than any other virus that causes vomiting/diarrhea (except that smell! And the length was longer than any other bug we've had)
Interestingly, when my second son got it (and was hospitalized), my first son, who had had it pretty badly two years before, also got sick. For a much shorter time (one day of vomiting, two days of diarrhea) but he definitely did get sick. It kind of surprised me, I thought that one exposure conferred immunity. My husband was feeling a little under the weather too, so it appeared to have effected him a bit.
