Doctor's answer:

Personal Preventive Measures
1. After meals, before and after using the toilet, and after going outdoors, children should wash their faces with soap or hand sanitizer. Do not let children drink untreated water or eat raw, cold food, and avoid contact with sick children.
2. Caregivers should wash their hands before touching children, after feeding infants, and after handling feces, and properly dispose of waste.
3. Bottles and nipples used by infants and young children should be thoroughly cleaned before and after use.
4. During outbreaks of this disease, it is advisable not to take children to crowded or poorly ventilated public places. Pay attention to maintaining a clean home environment, ensuring rooms are frequently ventilated, and frequently air out bedding.
5. If children show symptoms again, they should seek medical follow-up promptly.
