Is having white spots at the age of four or five a disease?

Patient's question:

I want to know the situation

Doctor's answer:

Hello, the four-year-old child currently has a white discharge. Does the child have any itching or discomfort? It's necessary to clean the child regularly, and the diet should also be light.
Advice: Use tea water to clean, and the clothes of the adults and the child should be washed separately. Apply erythromycin externally and wait and see.
