[|Human|] Hi, may I answer your health queries right now ?  Please type your query here...Hi, My son is 3 years old and has been having fever of 38-39deg. Celsius for the past 3-4 days.  He only has a slightly blocked nose otherwise no other symptoms.  I need to give him paracetamol or nurofen every 5-6 hours to help control his fever.  Should I be worried?
[|AI|]  Every illness even in the mildest form can progress or can take any shape, so answering that nothing to worry is not right, upper respiratory infection is the commonest illness however they can progress to lower respiratory tract or chest over few days, but most of the upper respiratory infections healed by themselves with help of supportive treatment so a check or monitoring on a child has to be done during even simple cough Cory. You can keep watch on his breathing rate, chest in Chat Doctor.  If the symptoms of fever and congestion of nose not improves by day 6 then antibiotics be needed to start, but please ensure to get your child checked if it not resolves, persist or worsen.
