Respiratory Syncytial Virus (RSV)

Respiratory Syncytial Virus (RSV), or RSV, is a common virus that causes infection in the lungs and respiratory system, especially the small airways called bronchioles. Therefore, it is the most common cause of bronchiolitis.


It is a condition more common in children around 2 years of age than in adults.


With proper treatment and a strengthened immune system, symptoms are mild, very similar to those of a cold, with a recovery time of one to two weeks. But, it can also be serious, especially in infants, older adults, people with compromised immune systems, people with chronic lung disease, or a congenital heart condition.



What are the symptoms of RSV?

The first signs usually appear 4-6 days after being infected. Some symptoms may be:

  • Runny nose

  • Dry cough

  • Fever

  • Throat pain

  • Sneezing

  • Wheezing


As it spreads, the symptoms become more intense, causing pneumonia or bronchiolitis.


In this table, we show you the difference and similarity between the most common respiratory conditions currently, including Covid-19:




How is RSV spread?

The Respiratory Syncytial Virus (RSV) is spread when an infected person coughs or sneezes, releasing the droplets to another person.

In the case of children, if they are in contact with another person who has the virus or touches an infected surface and then touches their face (eyes, nose and mouth), there may also be contagion.



Is RSV seasonal?

Indeed, RSV is seasonal, as is the influenza virus. It can start from late fall to early spring.



At-risk group

People most at risk of serious infections are:

  • The babies

  • Children with congenital heart or lung disease

  • Children and adults with weakened immune systems

  • Adults with lung problems or heart disease

  • Older adults



How to prevent RSV?

Since there is no vaccine against this virus, some healthy habits can help us stop the spread:

  • Wash your hands frequently and teach your children to wash properly

  • Avoid exposure, do not visit someone infected

  • Cover your mouth and nose when sneezing and coughing

  • Keep your objects clean (door handles, kitchen, bathroom and mobile devices)

  • Don't smoke in front of a baby

  • Wash and disinfect your baby's toys regularly


If your baby is infected, throw away the disposable tissues immediately and call your Pediatrician. Timely care is extremely important.
