Based on the description, it can be inferred that the child may have Hand, Foot, and Mouth Disease. The symptoms of Hand, Foot, and Mouth Disease are very similar to those of herpangina, but if blisters appear on the hands, feet, and around the anus, it is mostly Hand, Foot, and Mouth Disease. The illness usually lasts for about 7-10 days, with the specific recovery time depending on the condition. It is recommended to take the child to the hospital for a diagnosis as Hand, Foot, and Mouth Disease can be harmful to children. Under the guidance of a doctor, treatment should be administered. While giving the child some juice to supplement vitamins and prevent diarrhea, it is hoped that the child will recover quickly!
