Bronchiolitis is caused by the narrowing of the small airways in the lung (bronchioles). This narrowing may be caused by several viruses, particularly the Respiratory Syncytial Virus (RSV). While infants with RSV develop bronchiolitis, older children and adults may just develop cold symptoms. This virus is found in nasal secretions of infected individuals. It is spread by sneezing, coughing, hand-to-nose or hand-to-eye contact.

• ​Wheezing: a high-pitched whistling sound produced when breathing out.
• Rapid breathing with a rate of over 40 breaths per minute.
  
• Laboured or difficult breathing.
  

 
The symptoms may worsen over 3 to 5 days before improving. The wheezing may last for more than 7 days and the cough, more than 14 days.

​Administer the medicine as prescribed by your doctor to your child. Continue the medicine until your child's wheezing is gone for at least 24 hours. In addition, your child can be given paracetamol every 4 to 6 hours if the fever is over 38°C

Children with bronchiolitis usually do not need to be hospitalised unless they are very breathless, need oxygen or are not eating or drinking well.

​What can I do for my child at home?

• Nasal washes for a blocked nose
  

If your child's nose is blocked, he or she may not be able to breastfeed or drink from a milk bottle. Place 3 drops of saline in each nostril. After about 1 minute, use a soft rubber suction bulb to suck out the mucus. You can repeat this several times until your child's breathing through the nose becomes quiet and easy.



• Feeding
  

Encourage your child to drink adequate fluids. Feeding is often tiring so offer your child formula or breast milk in smaller amounts at more frequent intervals. If your child vomits during a coughing spasm, you may feed the child again.



• No Smoking
  

Tobacco smoke aggravates coughing. The incidence of prolonged wheezing increases greatly in children who have an RSV infection and are exposed to passive smoking. Do not let anyone smoke around your child, especially in your home.

Bring your child to the Children's Emergency immediately if:

• Your child's breathing becomes laboured or difficult.
  
• Your child's breathing is faster than 40 breaths per minute when he or she is not crying.
  
• Your child is lethargic, refuses to eat or drink, is irritable or unusually restless
