Roseola in infants is an acute febrile and rash disease, caused by human herpesvirus type 6 or 7. The fever usually lasts 3-5 days, with high fever as the main symptom. During this period, infants may also experience other symptoms such as decreased appetite, vomiting, or diarrhea, which can affect the function of the digestive system, leading to indigestion. It is recommended that the diet be light and easy to digest, avoiding spicy, stimulating, and greasy foods, as these are not conducive to digestion nor beneficial for recovery from the illness.
