Respiratory syncytial virus (RSV) is a common respiratory virus that affects the nose, throat and lungs. In most children, RSV causes symptoms similar to a common cold and improves with supportive care. However, in infants and young children, particularly those with certain risk factors, the infection can sometimes progress to more serious respiratory illnesses such as bronchiolitis or pneumonia.
Understanding the symptoms of RSV and knowing when your child needs medical attention can help parents respond promptly.
What is Respiratory Syncytial Virus?
RSV is a highly contagious virus that spreads through respiratory droplets and close contact with an infected person or contaminated surfaces. Almost all children experience an RSV infection at least once by the age of two, and reinfections can occur throughout life.
For many children, RSV causes a mild respiratory infection. However, in babies and younger children, the smaller airways can become inflamed and filled with mucus. This may lead to bronchiolitis, making breathing more difficult.
What Are the Symptoms of RSV in Children?
RSV symptoms may initially look like those of a common cold and often develop gradually. Common symptoms include:
- Runny or blocked nose
- Sneezing
- Cough
- Fever
- Reduced appetite
- Irritability or tiredness
- Wheezing or noisy breathing
In infants, particularly very young babies, symptoms may be less obvious. A baby may simply become unusually irritable, less active, feed poorly or develop breathing difficulties. Some young infants may face breathlessness or their breathing may appear paused. Fever may of may not be present.
As the infection progresses, some children may develop rapid breathing, wheezing or increased effort while breathing.
Which Children Are at Higher Risk?
Although any child can develop RSV, severe illness is more likely in:
- Young infants, especially those below six months
- Babies born prematurely
- Children with chronic lung disease
- Children with congenital heart disease
- Children with weakened immune systems
- Children with certain neuromuscular conditions
The younger the child, the greater the risk of severe RSV infection.
How Can Parents Tell If RSV Is Becoming Serious?
Parents should pay particular attention to their child's breathing and fluid intake.
Seek medical attention promptly if your child:
- Is breathing very fast or struggling to breathe
- Has visible pulling in of the ribs or chest while breathing
- Develops persistent wheezing or noisy breathing
- Is unable to drink or breastfeed adequately
- Has significantly fewer wet diapers
- Becomes unusually sleepy, weak or difficult to wake
- If the child’s breathing appears to pause in between
- Develops bluish or greyish lips or face
Breathing difficulty, poor fluid intake or worsening symptoms should not be ignored, particularly in infants.
How Is RSV Diagnosed?
RSV can resemble several other respiratory infections, including the common cold, influenza and other viral illnesses. A pediatrician or pediatric pulmonologist can assess the child's symptoms, breathing pattern and oxygen levels and examine the chest.
In some situations, an RSV test may be recommended. However, not every child with a cold-like illness needs testing. The need for testing depends on the child's age, symptoms, severity of illness and clinical assessment.
How Is RSV Treated?
There is no routine specific antiviral treatment required for most children with RSV. Treatment is mainly supportive, helping the child breathe comfortably and stay hydrated while the body fights the infection. Most uncomplicated infections improve within one to two weeks.
Depending on the severity of illness, treatment may include:
- Adequate fluids and feeding
- Nasal saline and gentle suctioning to clear secretions
- Fever management as advised by the pediatrician
- Oxygen support if oxygen levels are low
- Hospital care when breathing or hydration becomes a concern
Parents should avoid giving cough and cold medicines to young children unless specifically advised by their doctor. Moreover, good hydration should be maintained at all times.
Can RSV Be Prevented?
Good hygiene can reduce the spread of RSV. Parents can help protect children by:
- Washing hands frequently with soap and water
- Avoiding close contact with people who are unwell
- Keeping sick children at home when appropriate
- Cleaning frequently touched surfaces
- Teaching older children to cover coughs and sneezes
- Avoiding exposure of young infants to crowded settings or people with respiratory infections when possible
There are also RSV prevention options for infants, including maternal RSV vaccination during pregnancy and long-acting monoclonal antibodies for babies. Recommendations and availability can vary as per the child's individual risk factors, so parents should discuss the appropriate option with their obstetrician or pediatrician. However, since it is not a routine universal vaccination precautions are crucial for prevention of infections.
When Should You See a Pediatric Pulmonologist?
Most children recover from RSV without complications. However, specialist evaluation may be useful when a child develops significant wheezing or breathing difficulty, has recurrent respiratory symptoms, has an underlying lung condition, or experiences complications such as severe bronchiolitis or pneumonia.
Early medical assessment is particularly important for young infants and children who are at higher risk of severe disease.
