What are the signs of a respiratory tract infection?

Infections of your child’s nose, sinuses, throat, airways, or lungs are called respiratory tract infections. Most respiratory tract infections are caused by a virus infection and get better without treatment, but in some cases you might need to seek help.

Upper respiratory tract infections

Infections of the nose, sinuses and throat are called upper respiratory tract infections. Children usually get more of these because they are not yet immune to the viruses that usually cause them. Most of the time they will recover by themselves.

Common symptoms of an upper respiratory tract infection are:

  • a runny nose
  • coughing
  • a high temperature
  • sore throat, earache, or other aches and pains
  • noisy breathing (you may hear a wheeze or a whistle)
  • problems with feeding and drinking because of difficulty breathing
  • increased breathing through the mouth if they have a blocked nose.

If your child has a sore throat from an upper respiratory tract infection, they may not want to eat or drink. It’s a good idea to give them soft foods that will be easier to swallow. Very young children may dribble more if they find swallowing difficult.

Lower respiratory tract infections

Infections that affect your child’s main airways and lungs are called lower respiratory tract infections (chest infections).

As well as symptoms similar to upper respiratory tract infections, your child may have:

  • high temperature
  • coughing and vomiting with coughing
  • breathing difficulties (breathing fast, making a noise when they breathe or struggling to breathe)
  • drowsiness
  • a change in skin colour.

If your child gets recurrent infections

If an infection does not go away or keeps returning, then this could be a sign of an underlying problem. Find out more in our information about going to the doctor.

How many coughs and colds are normal?
