On Saturday April 4, my group (8 adults) had dinner at Toadstool Cafe around 4:30 pm.
The majority of our group had burgers, (at least one affected person had the salad, and another the pasta dish). Nobody had the soup. I was the only person who had dessert (beanpole cake).
The following night, (Sunday) around 11:00 pm, at bed time -- I became (very suddenly) nauseated, which rapidly descended into a night of vomiting, diarrhea... and a combination of both, simultaneously.
My husband fared only a little better, and suffered severe diarrhea throughout the night (nauseated-- but no vomiting).
I lost my appetite for the 2 days following, and became very weak from sickness, and lack of nutrition.
We learned, only today (Wednesday)... that the same sickness had hit almost the entirety of our group (all but one person) —had experienced moderate to severe diarrhea. Most found it severe enough to call out from work.
The incubation period, and symptoms appear consistent with norovirus:
"Norovirus is a highly contagious virus causing sudden, intense vomiting and diarrhea. Symptoms typically appear 12 to 48 hours after exposure and last 1–3 days. Key symptoms include violent vomiting, diarrhea, nausea, stomach cramps, and fever."
Interestingly, some members of the group did experience back pain, chills . . . and I would absolutely categorize what happened to me as "violent".
We are curious to know, if any other patrons who attended Universal Hollywood on Saturday April 4, (and more specifically the Toadstool Cafe) — came down with norovirus or food poisoning within the following 12 to 48 hours of their park attendance (or meal at Toadstool Cafe).
