Anyone’s baby have a stomach bug?

How long does the diarrhea last? It’s been 8 days for my little one. She stopped vomiting after the first three days. The diarrhea just won’t go away though. Kind of wondering if it could be related to the tap water I’ve been using for the last few days since I ran out of purified water. I have her back on purified water so I’m hoping this improves it. Thankfully she’s acting totally normal. No signs of dehydration.
