During a cold, children may experience a low fever or even persistently high fever. A persistent low fever indicates that the child has not fully recovered from the illness, reflecting the recovery phase, or that the fever-reducing method being used may be inappropriate.

In addition to administering oral cold medications based on the child's symptoms during a cold, oral antiviral medications can also be given to treat the illness jointly. Simultaneously, timely fever reduction measures should be implemented for children. A low fever, typically defined as a body temperature below 38.1°C, does not require oral fever-reducing medications. One can encourage the child to drink more water, frequently feed warm water, or repeatedly wipe the body with warm water, all of which can effectively reduce fever. If the low fever persists, it may be necessary to take the child to the hospital for a blood test to determine the appropriate medication for treatment based on the actual situation.
