Bronchiolitis is different from bronchitis, which causes a cough with lots of mucus and can affect people of all ages.
The early symptoms of bronchiolitis are similar to a cold, such as sneezing, a runny or blocked nose and a slightly high temperature.
A child with bronchiolitis may then get other symptoms, such as:
- a cough
- breathing more quickly
- finding it difficult to feed or eat
- noisy breathing (wheezing or crackling sounds)
- becoming irritable
Symptoms are usually worst between days 3 and 5, and the cough usually gets better in 3 weeks.
Call 999 if:
- your child is having difficulty breathing – you may notice grunting noises, their tummy sucking under their ribs or they may be breathing quickly
- there are pauses when your child breathes
- your child's skin, tongue or lips are blue or grey – on brown or black skin, this may be easier to see on the palms of the hands, soles of the feet, lips, gums and inside the eyelids
- your child is floppy and will not wake up or stay awake
As a parent, you may know if your child seems seriously unwell and should trust your own judgement.
Ask for an urgent GP appointment or call 111 if:
- your child has had a cold and it's getting worse
- your child is feeding or eating much less than normal
- your child has had a dry nappy for 12 hours or more, or shows other signs of dehydration
- your baby is under 3 months and has a temperature of 38C, or is older than 3 months and has a temperature of 39C or higher
- your baby feels hotter than usual when you touch their back or chest, or feels sweaty
- your child has a very high or low temperature, feels hot or cold to the touch, or is shivering
- your child is very tired, irritable or does not seem themselves
- you're worried about your child
There's no specific treatment for bronchiolitis. It usually gets better on its own and you can look after your child at home.
But it can be serious in some children, who may need to be treated in hospital.
Do
give children's paracetamol to babies and children over 2 months old or ibuprofen to babies and children over 3 months old if they're distressed or uncomfortable – do not give these medicines at the same time
keep your child upright as much as possible when they're awake – this will help them breathe more easily
check on your child regularly, including during the night
encourage your child to drink lots of fluids – try smaller feeds more often in babies, and give older children extra water or diluted fruit juice
Don't
do not smoke around your child
do not try to lower your child's temperature by sponging them with cool water or taking off all their clothes
do not give aspirin to a child under 16
There are some things you can do to lower the chances of your child getting bronchiolitis or spreading the viruses that cause it, such as:
- wash your hands and your child's hands often
- wash or wipe down toys and clean surfaces regularly
- avoid sharing things like cutlery and cups
- use disposable tissues and throw them away as soon as you've used them
- keep newborn babies away from anyone with a cold or the flu – especially if they were born prematurely or have serious health conditions
It's also important not to smoke around your child. Children who breathe in cigarette smoke have a higher risk of getting severe bronchiolitis.
RSV vaccination
The RSV vaccine helps reduce the risk of a common infection called respiratory syncytial virus (RSV) causing problems such as bronchiolitis.
The vaccine is available on the NHS from 28 weeks of pregnancy. This will help protect your baby and reduce the risk of severe RSV for the first 6 months after they're born.
It's also offered to adults aged 75 to 79.
Children at risk of severe bronchiolitis
Some children may have a higher risk of getting seriously ill with bronchiolitis.
This includes children who:
- were born very prematurely
- have a heart or lung condition
- have a weakened immune system
These children may be given an injection of infection-fighting antibodies each winter. This helps reduce the risk of RSV causing severe bronchiolitis.
Bronchiolitis is caused by a viral infection, usually respiratory syncytial virus (RSV).
RSV is very common and spreads easily in coughs and sneezes. Almost all children get it at least once before they're 2 years old.
It's not usually serious, but some babies and children have a higher risk of getting seriously ill, particularly:
- babies under 6 months old
- babies and children who were born prematurely
- babies and children with a weakened immune system, or long-term lung or heart conditions
