Thank you for your query on Healthcare Magic.
Your child seems to have a Viral fever
with an upper rspiratory tract infection.
Continue to give Tylenol
in prescribed dosage every 8th hourly depending on the presence of fever.
Do tepid sponging with lukewarm water whenever there is a high grade fever.
Give plenty of oral fluids and maintain his hydration.
Provide rest to the child.
If the fever is not coming down within next 24 to 48 hours consult the doctor again for re evaluation and for further treatment.
Hope I have answered your query.
