There are many common respiratory viruses seen in children, which most will have had by the time they turn 2.

However, in children under 2, the more serious consequences can lead to bronchiolitis, infection of the lower airways, that can make the airways inflamed and mucusy making it harder to breath.
The early symptoms of bronchiolitis are similar to those of a common cold, such as a runny nose and a cough.
Further symptoms can develop over the next few days, and may include:


Most cases of bronchiolitis are not serious, but you should contact your GP or call NHS 111 if:

Dial 999 for an ambulance if:

Good respiratory and hand hygiene can reduce the spread of these infections. Parents are advised to carry tissues and use them to catch coughs or sneezes, bin the used tissues as soon as possible and wash your hands with soap and warm water to kill the germs.

Children with flu or bronchiolitis symptoms should stay home and reduce contacts where possible.

Most cases are not serious and clear up within 2 to 3 weeks, but the symptoms can be very worrying for parents. For some infants and babies, such as those born prematurely or with a heart condition, bronchiolitis can be more severe. NHS 111 or your GP can offer advice if any parent has concerns.

It is perfectly okay for parents to ask people with colds to keep away from newborn babies, particularly in the first two months, and for babies born prematurely.
