Disease description:

A child in the family contracted influenza B at school. Today, when taking his temperature, it was found to be relatively low, and he also complained of feeling very cold. Could you please explain why this might happen?

Dr. Zhou Xiaofeng
After influenza B, if a child has low body temperature and complains of feeling cold, it may be due to dysfunction of the body's temperature regulation center caused by the viral infection, leading to a drop in body temperature. In such cases, the child may feel cold as a result of hypothermia. Parents are advised to closely monitor the child's temperature, appropriately add clothing to keep the child warm, and promptly consult a doctor to determine whether further treatment is needed, ensuring the child recovers as quickly as possible.
