I think it was going around the Grand Canyon last summer - not sure if that was your trip: https://www.npr.org/2022/09/24/1124...to-a-stomach-bug-outbreak-at-the-grand-canyonUgh, I'm sorry. We took a raft trip last year and the guides were obsessed with hand washing - you basically weren't allowed to touch any food until you'd washed your hands. My hands were a chapped mess by the end of the trip, but we were mainly grateful that they were very, very serious about no one getting norovirus. I'm not sure I've ever had the pukes as badly as some of the experiences in this thread.
Hope you recover quickly, @Amie H !!
