Doctor's answer:

Based on the condition, it could be considered as rotavirus infection in children, which is a type of autumnal gastroenteritis. It is important to promptly receive intravenous fluid and nutrition in the hospital to prevent dehydration, and to monitor for any signs of electrolyte imbalances. If treatment is delayed, the consequences can be severe, potentially leading to life-threatening complications.
I recommend searching for "rotavirus" for more information, as this website has resources available for. My 19-month-old daughter recently had a rotavirus infection and was experiencing vomiting and diarrhea for four days before finally improving. It is crucial to adhere to treatment and maintain fluid intake promptly. Otherwise, dehydration may progress to severe dehydration, which will be very difficult to treat and pose significant risks!
However, this illness has a typical duration, usually requiring about seven days to recover. Since it has only been three days so far, please continue with treatment—it will be effective. Additionally, in terms of diet, it should be light, easy to digest, and avoid raw, cold, greasy, or high-protein foods. Let the child eat according to their appetite without forcing them.
After receiving injections and medication, try to ensure the child gets plenty of rest and follows their wishes as much as possible. By the fourth or fifth day, the condition should begin to improve.
