What should I do if the baby suddenly has a fever?

Patient's question:

The baby suddenly has a fever of 37.5 degrees now. We have been using physical cooling methods. The baby has been in good spirits today, but has a bit of a runny nose at night. After just falling asleep, the baby coughed twice.

Doctor's answer:

The most common cause of fever in infants is a cold, which is also known as acute upper respiratory tract infection. It is recommended to check the child's complete blood count to determine the cause. If the lymphocyte count is higher in the white blood cell classification, it suggests a viral infection. If the neutrophil count is higher, it indicates a higher likelihood of a bacterial infection.
Here are some suggestions for managing fever in children:
It is recommended to use physical cooling methods for fever. For temperatures below 38.5°C, frequent lukewarm sponge baths can be effective. Using warm towels to wipe the limbs and back can help lower the temperature. Even a warm bath for the child can be helpful, as long as you take care to prevent them from getting cold again.
