RSV infection is a respiratory illness caused by the Respiratory Syncytial Virus, primarily affecting infants, young children, and older adults.
What Is an RSV Infection?
An RSV infection is caused by the Respiratory Syncytial Virus (RSV), a common RNA virus belonging to the family Pneumoviridae. RSV is one of the leading causes of respiratory tract infections in young children and can also cause serious illness in older adults and immunocompromised individuals. Almost all children will have been infected with RSV at least once by the time they reach two years of age.
Causes and Transmission
RSV spreads primarily through droplet transmission -- when an infected person coughs or sneezes and others inhale the virus-containing particles. It can also spread via direct contact with contaminated surfaces, as the virus can survive on hard surfaces for several hours.
- Close contact with an infected person
- Touching contaminated objects such as toys or door handles
- Shared spaces such as daycare centers or nursing homes
In temperate climates, RSV season typically runs from autumn through spring.
Symptoms
Symptoms vary depending on the age and overall health of the person affected.
Mild Symptoms (common in older children and adults)
- Runny or stuffy nose
- Cough
- Mild fever
- Sore throat
- General feeling of illness
Severe Symptoms (common in infants and high-risk groups)
- Bronchiolitis: inflammation of the small airways causing breathing difficulties
- Wheezing (a whistling sound when breathing)
- Rapid breathing and chest retractions
- Poor feeding and reduced appetite in infants
- Pneumonia in severe cases
- Low blood oxygen levels (cyanosis) in very severe cases
Risk Groups
Certain groups of people are at higher risk of developing severe RSV illness:
- Infants under 6 months of age, especially premature babies
- Children with congenital heart disease or chronic lung conditions
- Immunocompromised individuals
- Adults aged 65 and older
- People with underlying conditions such as COPD or heart failure
Diagnosis
RSV infection is diagnosed based on clinical presentation and confirmed with laboratory testing.
- Rapid antigen test: Detects RSV antigens from a nasal swab; results are available quickly but sensitivity is lower
- PCR test (polymerase chain reaction): Highly sensitive detection of viral RNA; considered the gold standard
- Blood tests and inflammatory markers: Help assess disease severity and rule out secondary bacterial infections
- Chest X-ray: Indicated when pneumonia or severe bronchiolitis is suspected
Treatment
There is currently no broadly available specific antiviral therapy for RSV. Treatment is therefore primarily supportive and symptomatic.
General Measures
- Adequate fluid intake and rest
- Nasal decongestant drops to improve breathing
- Fever-reducing medications such as paracetamol or ibuprofen (age-appropriate dosing)
Hospital Treatment for Severe Cases
- Supplemental oxygen when blood oxygen levels are low
- Intravenous fluids when oral intake is insufficient
- Mechanical ventilatory support in very severe cases
- Palivizumab: A monoclonal antibody used for prophylaxis in high-risk infants such as premature babies or children with heart defects
Prevention and Vaccination
Significant advances have been made in RSV prevention in recent years:
- RSV vaccines for adults aged 60 and over: Since 2023, RSV vaccines (e.g., Abrysvo, mRESVIA) have been approved in Europe and the United States for older adults.
- Nirsevimab (Beyfortus): A long-acting monoclonal antibody recommended as passive immunization for newborns and infants during their first RSV season.
- Maternal vaccination during pregnancy: The Abrysvo vaccine is also approved for use in pregnancy to protect newborns through maternally transferred antibodies.
- General hygiene measures: Regular handwashing and avoiding close contact with infected individuals.
