Causes of Respiratory Syncytial Virus

  • RSV enters through your eyes, nose or mouth.
  • Passed through direct contact, sneezing and coughing.
  • After touching a contaminated object you are susceptible to get the virus.
  • An infected person is most contagious after the first few days but can pass the virus along up to a week after infection.

Individuals at Higher Risk

  • Premature infants.
  • Children under 8 to 10 weeks of life who were born with heart or lung disease.
  • Babies and young children whose immune systems are weakened.

Pathophysiology of Respiratory Syncytial Virus

  • RSV is a nonsegmented, negative-stranded RNA virus.
  • Begins with replication of the virus in the nasopharynx.
  • The virus spreads to the small bronchiolar epithelium.
  • This leads to small airway obstruction.



-Pneumonia or bronchiolitis: Inflammation of the lungs (pneumonia) or the lungs' airways (bronchiolitis).

-Middle ear infection: When microorganisms enter the space behind the eardrum.

-Asthma: May result later in life due to RSV.
