What is Respiratory Syncytial Virus (RSV)?

Respiratory Syncytial Virus (RSV) is a common respiratory virus that leads to mild, cold-like symptoms in most individuals. However, it can cause severe illness, particularly in infants and elderly people. RSV is noteworthy for being the most frequent cause of bronchiolitis (inflammation of the small airways in the lung) and pneumonia in children under one year of age in the United States.

Epidemiology: Who is Most at Risk?

RSV can affect individuals of any age, but certain groups are at a higher risk for severe illness:

  • Infants and Young Children: Especially those under two years old, with the highest risk in the first few months of life.
  • Elderly Adults: Older adults, particularly those aged 65 years and older, are at risk for severe RSV infection.
  • People with Chronic Health Conditions: Individuals with chronic heart or lung diseases, or those with weakened immune systems, are more susceptible to serious complications from RSV.
  • Premature Infants: Babies born prematurely have less mature lungs and immune systems, making them more vulnerable to RSV infections.
Common Symptoms and Complications of RSV

Symptoms of RSV typically include:

  • Runny nose
  • Decrease in appetite
  • Coughing
  • Sneezing
  • Fever
  • Wheezing

In severe cases, RSV can lead to more serious complications, such as:

  • Bronchiolitis: A severe lung infection that inflames the bronchioles.
  • Pneumonia: An infection of the lungs that can be particularly dangerous in infants and elderly people.
  • Respiratory Failure: A critical condition that occurs when severely restricted airflow leads to dangerously low levels of oxygen in the blood.
  • Hospitalization: Particularly in severe cases or when patients have underlying health conditions that exacerbate the virus’s effects.

However, understanding the risk factors and recognizing the symptoms of RSV can help in managing and preventing severe outcomes, particularly among the most vulnerable groups.

Diagnosing Respiratory Syncytial Virus (RSV)
