What is Childhood Bronchiolitis?

Bronchiolitis is a chest infection caused by a virus that affects bronchioles, the small breathing tubes in the lungs, causing babies and small children to cough, wheeze and have trouble breathing. It is a common infection in the first year of life, and especially in babies under six months of age. 

The disease is usually caused by a viral infection, and many viruses can cause the illness with the most common being RSV (respiratory syncytial virus). It is infectious and is usually caught from a close contact who has a cold or cough. It can make babies sick for three to seven days, and the cough can last for several weeks.

Some of the symptoms of bronchiolitis are

  • difficulty breathing
  • a runny nose
  • a fever for two to three days
  • coughing and wheezing which may continue from ten days to one month

If your baby is unwell and coughing it will be important to see your doctor for a check to see if it is bronchiolitis or if there is something else causing the cough.
