What is bronchiolitis?

Bronchiolitis is when the smallest air passages in your baby’s lungs become swollen. This can make it harder for your baby to breathe.

Bronchiolitis is usually caused by a virus called respiratory syncytial virus (known as RSV). Almost all children will have had an infection caused by RSV by the time they are two years old. 

RSV is more common in the winter months. Most children will only have mild ‘cold-like’ symptoms and will get better on their own. Some babies can find it hard to breathe or feed and may need to go to hospital.

The virus that causes bronchiolitis in babies also causes coughs and colds in older children and adults, so it is very hard to prevent your child getting it.

What are the symptoms?
  • Bronchiolitis starts like a simple cold. Your baby may have a runny nose and sometimes a fever (high temperature) and a cough
  • After a few days your baby’s cough may become worse. Your baby’s breathing may be faster than normal, and it may become noisy. Your baby may need to make more effort to breathe
  • In very young babies' bronchiolitis can sometimes cause them to have brief pauses in their breathing (we call these apnoeas)
  • If your baby is working harder to breathe it can make it harder for your baby to feed. They may take less milk than normal from the breast or bottle. Your baby may have fewer wet nappies than usual.

 

How can I help my baby?
  • If your baby is finding it hard to feed, try breastfeeding more often or giving smaller bottle feeds more often
  • If your baby has a fever, you can give them paracetamol (such as Calpol). Follow the instructions that come with the paracetamol carefully.
  • Your local pharmacist can help you know when to give your baby paracetamol and how much paracetamol to give. Do not give paracetamol to babies under 3 months of age unless your doctor or a health professional has told you to
  • Too much paracetamol can be harmful. If you think your baby has had too much paracetamol call NHS 111
  • You should carry on giving any medicines or inhalers that your baby usually takes. If you find it hard to get your baby to take them, ask your doctor for advice
  • Bronchiolitis is caused by a virus. Antibiotics will not help a viral infection. Most children with bronchiolitis do not need antibiotics.
  • Occasionally children with bronchiolitis can become unwell with another illness. Get medical advice if your child was getting better but has a new fever or is getting worse
  • Call your GP or NHS 111 to get medical advice

Make sure your baby is not exposed to tobacco smoke. Passive smoking can seriously damage your baby’s health. It makes breathing problems like bronchiolitis worse.

If you would like help to give up smoking you can get information / advice from your local pharmacist, GP surgery or by calling the Quit Your Way Scotland helpline on 0800 84 84 84 Mon-Fri 0800-2200 and Sat-Sun 0900-1700.

How long does bronchiolitis last?
  • Most children with bronchiolitis will seem to get worse during the first 1-3 days of the illness. They often begin to improve over the next two weeks. The cough may go on for a few more weeks.
  • Your child can go back to nursery or day care as soon as he or she is well enough (feeding as normal and with no difficulty in breathing)
  • If you are worried your child is unwell or is not getting better see your doctor
