Question
A 4-year-old child has been experiencing persistent diarrhea for two months, and the parents are worried and seeking medical advice.
Answer
For a child with persistent diarrhea, a stool test should be conducted first to determine whether it is a bacterial or viral infection. If the result shows a bacterial infection, antibiotic treatment is required. If it is a viral infection, antibiotics are not needed; instead, oral probiotics should be taken, and symptomatic treatment should be provided for accompanying symptoms such as fever. In daily meals, avoid cold and irritating foods, ensure that all food is warm, do not eat leftover rice or cold dishes, and even in winter, avoid sitting on cold benches.
