Official Answer by Drugs.com


Respiratory syncytial virus (RSV) symptoms include runny nose, sore throat, stuffy nose, cough, wheezing, headache, and fever with most people recovering after 1 to 2 weeks. In very young infants, respiratory syncytial virus (RSV) symptoms may be decreased activity, irritability, and breathing difficulties. RSV symptoms can become severe in some infants and older adults and may require hospitalization.

More severe infections may cause inflammation of the small airways (bronchiolitis) and may also cause pneumonia. RSV is the most common cause of pneumonia and bronchiolitis in children under 12 months old.

How to relieve symptoms of respiratory syncytial virus (RSV)

Mild RSV Symptoms

Serious RSV Symptoms

Some people with RSV may need to hospitalized if they are having trouble breathing or if they become dehydrated. In these cases, while in the hospital, they may require oxygen to help them breathe or IV fluids if they are unable to drink enough fluids.

If the RSV symptoms are severe, patients may need to be intubated, which is when a breathing tube is inserted through the mouth and down to the airway with mechanical ventilation which helps the person breathe.

Respiratory syncytial virus vaccines and antibodies

RSV vaccines

Respiratory syncytial virus immunization

Passive immunization with preventive antibody products

RSV antibody products can help prevent severe symptoms of RSV disease in infants and young children.

Beyfortus (Nirsevimab) can be used by infants younger than 8 months of age if they are born during RSV season or entering their first RSV season. Usually, infants that are younger than 8 months old do not need Beyfortus if they were born 14 or more days after their mother has had an RSV vaccine.

Belfortus may also be used for children aged 8 months through 19 months who are entering their second RSV season and have an increased risk of having severe RSV.

Synagis (palivizumab) can be given to children younger than age 24 months old with specific conditions that make them have an increased risk for severe RSV disease. Synagis is given once a month during the RSV season.

Enflonsia (clesrovimab-cfor) for newborns and infants who are born during or entering their first RSV season to prevent RSV complications and hospitalizations. Enflonsia is administered as a single intramuscular injection (into the muscle) for protection through a typical RSV season of 5 months.
