We were well enough by the 26th to travel to see my family in another state. My dad woke up in the morning of the 28th with the same unpleasant symptoms. We visited the extended family that day. We returned home on the 29th, and as of the 30th, 11 family members were infected. ELEVEN. I think my dad is the only one who had to get intravenous rehydration.
We are pretty amazing disease vectors, if I do say so myself.
Pine-sol, as it turns out, works perfectly for making it so that the house no longer smells like vomit.
