I believe this is rotavirus which is a common cause of fatal diarrhea in children. I think "wheel-like shape" is technically a buzz word for rotavirus, but I didn't know that. Yes, there is a vaccine, but it requires 2-3 shots giving within a month starting after 6 weeks of age so maybe this child isn't completely immune yet. Once you get to rotavirus you just need to know the rest and I linked the video below on how I remember all the viruses.
