Can a cold and fever enhance immunity?

Patient's question:

I recently experienced a recurrence of fever. Later, I heard from my friends that having a cold and fever can actually boost the immune system. I'd like to ask, does having a cold and fever really increase immunity?

Doctor's answer:

This statement is not absolute; it depends on each person's body. Everyone has different physical constitutions. If a child has a fever, it is still important to take them to the hospital in a timely manner. Fever is an immune response of the human body. Every time a baby has a fever, their body gains additional combat experience points. Therefore, fever can enhance the human immune system, and this statement is correct! However, every child has individual differences. Some children have strong resistance, while others have weaker resistance.
