What is the reason for the child's frequent fever?

Patient's question:

No

Doctor's answer:

Children with weaker constitutions frequently experience repeated respiratory infections such as colds, fever, cough, runny nose, sore throat, and swollen tonsils over a long period of time. This is mainly related to their low immune function, malnutrition or unreasonable diet, and inhalation of smoke, dust, or mites.
