I have to say that recently at a hotel pool I saw a sign reading “Dont swim if sick with diarrhea.
I had to ask myself, do people actually do that??? UGH I guess so.
Yes, they do and they let children who are not yet potty trained into the pool as well.
HI Express pool has sign which specifies having had chronic symptoms within the last 2 weeks. So if you had it last week even if you feel fine now, they want you to stay out of the pool.
