Respiratory illnesses are common among children, particularly when viruses circulate through schools, nurseries and other places where children spend time together. One virus parents may hear more about is respiratory syncytial virus, commonly known as RSV.
RSV can cause mild cold-like symptoms in many children, but it can sometimes lead to more significant breathing problems, particularly in babies and young children.
Dubai Health Authority issued an awareness circular in September 2026 highlighting the importance of prevention and vaccination against RSV.
Understanding the symptoms, risk factors and warning signs can help parents know when to monitor a child at home and when to seek medical advice.
What is RSV?
RSV stands for respiratory syncytial virus. It is a common respiratory virus that can affect people of all ages.
In children, RSV may initially look like an ordinary cold. Symptoms can include a runny nose, cough, reduced appetite and fever.
In some children, particularly infants and young children, the infection can affect the lower respiratory tract and cause conditions such as bronchiolitis or pneumonia.
The severity of an RSV infection can vary from child to child.
What are the symptoms of RSV in children?
Common RSV symptoms may include:
- Runny or blocked nose
- Cough
- Sneezing
- Fever
- Reduced appetite
- Tiredness
- Irritability
- Wheezing or noisy breathing
In babies, symptoms may sometimes be less obvious.
A young infant may feed less than usual, become unusually tired or show changes in breathing.
Parents should monitor their child’s overall condition rather than focusing on one symptom alone.
What does RSV look like in babies?
RSV can be particularly concerning in very young babies because they may not always develop the typical symptoms parents expect from a respiratory infection.
Parents may notice:
- Difficulty feeding
- Reduced interest in feeding
- Increased tiredness
- Irritability
- Cough
- Congestion
- Changes in breathing
If a baby appears unusually unwell or is having difficulty breathing or feeding, medical assessment is important.
Regular well-baby care can also help parents discuss respiratory symptoms, feeding concerns and other health questions with a paediatrician.
How does RSV spread?
RSV can spread through respiratory droplets and close contact with an infected person.
Children may be exposed through:
- Family members
- Nurseries
- Schools
- Playgroups
- Crowded indoor environments
- Shared surfaces and frequently touched objects
Good hygiene and reducing close contact with people who are unwell can help reduce the risk of transmission.
How can parents help prevent RSV?
There is no single measure that prevents every respiratory infection.
Parents can reduce the risk by encouraging healthy habits such as:
- Washing hands regularly
- Avoiding close contact with people who are sick
- Keeping sick children at home when appropriate
- Cleaning frequently touched surfaces
- Avoiding sharing cups, utensils and personal items
- Teaching children to cover coughs and sneezes
- Following recommended vaccination or preventive guidance where applicable
Dubai Health Authority’s September 2026 communication specifically highlighted prevention and vaccination against RSV. Parents should discuss eligibility and the most appropriate preventive options with a qualified healthcare professional.
Is there an RSV vaccine for children?
RSV prevention is not the same for every child.
Depending on age, health status and other factors, preventive options may be available for certain infants, children or pregnant women.
Parents should not assume that the same RSV prevention strategy applies to every child.
A paediatrician can review the child’s age, medical history and risk factors and advise whether a preventive option is appropriate.

Who is at higher risk of severe RSV illness?
Some children may have a higher risk of developing severe respiratory illness.
Risk may be influenced by factors such as:
- Young age, particularly infancy
- Premature birth
- Certain heart conditions
- Chronic lung conditions
- A weakened immune system
- Other underlying medical conditions
If your child has a chronic health condition, ask their paediatrician about respiratory infection prevention.

How is RSV treated in children?
Most RSV infections are managed with supportive care.
Treatment depends on the child’s symptoms and overall condition.
A doctor may recommend measures such as:
- Adequate fluids
- Rest
- Monitoring temperature
- Keeping the nose clear when congestion affects feeding or sleep
- Medical review when symptoms worsen
Antibiotics do not treat viral infections such as RSV unless a doctor identifies a separate bacterial infection.
Parents should avoid giving children medication without checking whether it is appropriate for their child’s age, weight and medical condition.
When should I take my child to a doctor for RSV?
Contact a paediatrician if your child has respiratory symptoms that are worsening, persistent or causing difficulty with feeding, sleeping or normal activities.
Medical assessment is particularly important if your child is very young or has an underlying medical condition.
A paediatrician can examine the child and determine whether further assessment or treatment is needed.
What are the emergency warning signs?
Seek urgent medical attention if your child develops signs of serious breathing difficulty or becomes significantly unwell.
Warning signs can include:
- Severe difficulty breathing
- Very rapid or laboured breathing
- Significant chest retractions
- Blue or grey colouring around the lips or face
- Severe weakness or unusual difficulty waking
- Significant difficulty feeding
- Signs of dehydration
- A sudden deterioration in condition
Do not wait for a routine appointment if your child appears seriously unwell.
RSV or a common cold: how can parents tell the difference?
RSV can initially resemble a common cold.
Symptoms such as a runny nose, cough and fever can occur with many respiratory viruses, so parents may not be able to identify RSV based on symptoms alone.
The more important consideration is how the child is breathing, feeding, drinking and behaving.
If symptoms are worsening or you are concerned about your child’s condition, a paediatrician can assess the child and determine the appropriate next steps.
Can children return to school or nursery after RSV?
The timing depends on the child’s symptoms, recovery and the policies of the school or nursery.
A child who is still significantly unwell, has difficulty participating normally or has a fever should generally be assessed before returning to normal activities.
Parents should follow medical advice and the relevant school or nursery requirements.
